Why yucca leaves turn yellow and dry: reasons, recommendations

Yucca is a very beautiful plant that looks like a lush palm tree. Yucca grows extremely slowly, but can eventually reach almost 4 meters in height, so it requires quite a lot of space.

If the leaves of this plant suddenly turn yellow and dry, this indicates errors in care, which in the future can even lead to the death of the plant.

Let's take a closer look at the questions : why do yucca leaves turn yellow and what to do if the leaves dry out and lose their healthy appearance.

Yucca: leaves turn yellow and dry, what to do

You can save your home yucca in 8 cases out of 10.
The main thing is to pay attention to the yellow signs of the palm tree in time, and then find the true cause, do the care correctly and carry out urgent rehabilitation

Diseases

Geranium diseases, geranium leaves turn yellow and dry - what to do?

Yucca is rarely attacked by disease. Often the cause of illnesses is frequent watering or overwatering of the flower. Diseases that can be identified by changes in foliage:

• brown spotting. The lower leaves are first covered with light spots, starting from the edges, then the entire leaf blade turns yellow, and then dark brown;
• leaf necrosis. This disease can be detected by small spots on the edges of leaf blades. The spots may be wet or dry.

Fungicides are used as treatment.

Important! The plant should be treated after the yellowed areas of greenery have been completely removed. Disease necrosis on yucca leaves

Pests

Insects parasitize on damaged flowers, the care of which is not adequate. On diseased yucca you can find:

• ticks;
• scale insect;
• aphids;
• caterpillars;
• thrips.

Pest damage over a long period of time is accompanied by yellowing and dying of foliage. Parasites can be controlled using insecticides.

Note! Regular inspections and preventive treatment will protect the palm tree from pests

Soil moisture

In relation to soil moisture, yucca is similar to succulents. This plant accumulates moisture in its trunk, and the dense leaves practically do not evaporate moisture from the greenery.

Important! Overwatering and frequent watering are detrimental to yucca. Yellowing of the lower leaves is one of the signals of an incorrect watering regime

Soon the leaves will begin to dry out, and this is a serious signal. Timely replanting of a flower will save its root system

Yellowing of the lower leaves is one of the signals of an incorrect watering regime. Soon the leaves will begin to dry out, and this is a serious signal. Timely replanting of a flower will save its root system.

Watering should be rare and only after the soil has completely dried. In winter, watering is reduced to once every 3-4 weeks. There should not be a lot of water, and excess should be immediately removed from the pan.

The thicker the trunk of the elephant yucca, the more moisture it contains.

Air temperature

Yes, yucca is a resident of the hot USA and Mexico. But its comfortable temperature of existence is 20-25 °C in summer. In winter, the flower sleeps, and it is better if during this period the temperature is reduced to 15 ° C.

Why do yucca leaves turn yellow in winter? Everything is simple here, if the pot is near the radiator, then the palm tree is hot, and the air is dry.

If the plant cannot survive in winter, another question arises for gardeners: why do the tips of the yucca leaves dry out? This is due to dry air. Infrequent spraying from a spray bottle is necessary.

Note! It is important to ensure that water does not accumulate at the base of the leaf.

Root rotting

Root rotting is accompanied by sharp yellowing and loss of leaves. The leaves begin to turn yellow and fall off, starting from the lower ones. This process can occur due to several gaps in care.

• Regular overflow of the flower. If a lot of excess water flows from the pot into the tray, the soil at the bottom of the pot is constantly moist. These excess moisture provoke rot of young roots.
• Frequent watering. If the soil does not dry out completely between waterings, the roots suffer from excess moisture. Watering is especially often disrupted in winter, when the temperature drops and watering is not reduced.
• Excessive watering also causes rot, even if not too much water flows into the pan. With abundant watering, rot can immediately spread to the trunk when water collects at its base.
• Lack of drainage. The holes at the bottom of the pot should be large so that air can also flow there. The drainage layer is made of light expanded clay or broken shards. The minimum drainage layer is 5 cm, it will protect against moisture accumulation.

If the yucca has stopped its growth and suddenly began to shed yellowed leaves, it urgently needs to be saved. As long as the rot has not risen up the trunk, the entire plant can be saved. An urgent transplant into new soil and restoration of the required maintenance conditions is what the indoor palm tree needs.

Important! If the soil used for replanting is wet (as from a purchased package), the plant is not watered for 2 weeks after replanting. Healthy root system of indoor palm tree

Other Possible Problems

Hamedorea flower - leaves dry, what to do

What other reasons could there be and what should you do if the leaves of the yucca palm turn yellow and dry? These problems can be of different nature.

Natural leaf shedding

From time to time, the lower leaves of the palm tree turn yellow and dry out. This is a sign of maturation and growth. The palm tree does not know how to shed dry leaves on its own. In order not to spoil its appearance, you need to pull the dry leaf down and carefully remove it from the trunk.

Lack of light

Yucca can grow in shade, but loves when there is enough light. In late autumn, when daylight hours are shortened, the exotic beauty suffers. It is necessary to organize artificial lighting for the plant so that its daylight hours are at least 10 hours.

Stress

After purchasing the plant, yellowing and drying of the greenery may occur. This is a reaction to a sharp change in conditions of detention, furnishings, and lighting. There is no need to rush to replant the palm tree in new soil. 10-14 days of adaptation will help the plant come to its senses.

Stress response causes yellowing of leaves other than just below

Rearrangement

Yucca is a homebody, and frequently moving it from place to place can also affect its decorative value. The leaf may wither, turn yellow and dry out. During such periods, flowers are especially weak to pests and diseases.

Note! The plant can easily tolerate rearrangement due to the change of season. In winter, this is a cooler room. In summer, yucca feels great in the open air of balconies and verandas.

No rest period

Most often, yucca begins to turn yellow precisely because of improper wintering. Conditions that spoil the appearance of a palm tree:

• heat;
• dry air;
• lack of light.

The ideal dormant period for yucca is:

• air temperature 15 °C;
• moderate air humidity;
• rare watering;
• sufficient lighting;
• daylight hours more than 10 hours.

Properly organized wintering ensures the preservation of decorative properties. And already in the spring, after awakening, the palm tree actively begins to grow green.

Rough soil change

The exotic root system is not very developed and very delicate. If you vigorously shake out old soil, the roots are easily damaged. After the transplantation procedure, the palm tree grows and restores roots for a long time, so it stops growing and can even shed the lower rows of leaves.

A regular palm tree transplant looks like transshipment. It is this procedure that will save the root system. And after the transplant, she will quickly restore her growth. Yellowing of a pair of leaves after transplantation is considered normal.

Important! If the roots of the flower are damaged during transshipment, they should be treated with crushed coal.

Yucca is a wonderful representative of the Agave family. This is a worthy decoration for any home, office or hall. The plant is not capricious, and its care requirements are easy to recreate in an ordinary apartment.

What to do if the leaves of cucumber seedlings on the balcony turn yellow

In general, the causes of yellowing leaves of cucumber seedlings are the same as those of mature plants, but there are several other possible factors that cause this problem.

1. Containers are too tight. If young plants begin to turn yellow, it is possible that the seedlings are simply cramped in the pots, and the root system cannot develop normally. The simplest solution is to transplant the seedlings into larger containers.

2. High humidity. To prevent fungal diseases from developing, regulate the air humidity by ventilating the balcony.

3. Improper watering. Leaves begin to turn yellow when over- or under-watered.

4. Lack of batteries. To prevent a deficiency of elements necessary for the good development of seedlings (and, consequently, yellowing of the leaves), feed the seedlings in the phase of 2-4 true leaves with complex nitrogen fertilizer (according to the instructions). Remember - you cannot feed cucumbers with organic matter before planting them in the ground.

You can make a mixture for feeding cucumbers yourself. To do this, dilute 10 g of ammonium nitrate, 10 g of superphosphate, 10 g of potassium sulfate in 10 liters of water. This solution is only suitable for root feeding - if it gets on the green parts of the plant, it can cause a burn.

Growing Yucca from Seeds

The most commonly used method is seed propagation of yucca.

• Seeds must be scarified: carefully break the dense shell of the seed with a needle or rub with sandpaper.
• Fill the box with a mixture of leaf, turf soil and sand in equal proportions. Plant the seeds to a depth of 2-3 cm.
• The distance between the seeds is 3-5 cm, but it is better to plant them immediately separately in cassette or peat cups.
• Cover the crops with glass or film. Sprout at an air temperature of 25-30 °C and bright, diffused lighting.

• Ventilate the shelter daily to remove condensation.
• In the first 10 days, maintain constant soil moisture, then moisten moderately.
• Shoots will appear in about a month.
• When 2 true leaves appear, plant them in separate containers with light nutrient soil.
• After 2 weeks, feed (1 g of nitrophoska per 1 liter of water).
• When 4-5 leaves appear, transplant into a pot and care for it as if it were an adult plant.

Why do yucca leaves fall off?

This is a very rare occurrence, because the decorative false palm tree is an evergreen plant and changes in nature do not affect its appearance. If the yucca is happy with its environment, it stays green all year round. If an indoor palm tree sheds its leaves, you need to understand the reason and, if necessary, take action.

The reasons for sudden exposure of the stem are:

1. Stress when changing location. A newly purchased yucca simply needs to be given time to adapt to its new environment. In this case, it will not hurt to replant the plant in fresh soil. A pot is chosen that is 2-3 cm larger, drainage made of expanded clay is placed on the bottom, and soil for palm trees or cacti is sprinkled on top.
2. Rough transplantation with damage to the root system. Yucca will adapt and throw out young shoots. Any root growth stimulator that is used in accordance with the instructions will help to ease the adjustment period.
3. Frequent watering. Rotting of the roots entails wilting of the yucca - death of the stem and shedding of leaves. In this case, you cannot do without a transplant. The rotten parts are removed, the cut of the intact lignified top is treated with crushed coal, placed for rooting in damp sand or vermiculite, and watered with epin according to the instructions.
4. High air temperature in winter with insufficient lighting. How to save yucca from baldness in this case? Provide the plant with cool air (+15 ⁰С) and additional lighting.

Botanical description - external qualities

Yucca belongs to evergreen plants from the Agave family. Outwardly, it looks like a medium-height tree with long and dense leaves with pointed ends. Among the existing species, of which there are approximately 50, some are used for growing in warm regions and countries, outdoors and at home.

Yucca is not only valued for its beautiful leaves, it has a rather attractive flowering period. At this time, large buds of white and cream tones appear on a long peduncle.

The homeland of yucca is South America; due to its external similarity and growing conditions, this plant is often confused with an ordinary palm tree.

The plant has a tree-like trunk, on which there is at least one growing point. They grow long leaves that can droop or erect. Properly carried out pruning of the trunk can give it an interesting shape and increase branching.

Interesting! Flowering and fruiting are observed only in natural conditions, thanks to pollination by a specific species of butterfly. Hybrid varieties can bloom, but this is extremely rare.

Flowering is possible only if growing conditions are created that are as close to natural as possible, and this can only be done in greenhouses. If everything is done correctly, the first buds will appear 7 years after planting in the summer.

Experienced gardeners have managed to stimulate flowering by creating coolness in winter. They create conditions in which the thermometer readings stay within 14 degrees Celsius during this period.

Ornamental yuccas differ from other plants in several common characteristics:

• yucca grows as a shrub or tree;
• it has dense and hard leaves of a single emerald color, but there are also patterns in the form of white veins;
• its leaf plates can be 100 cm long, they are collected into rosettes;
• paniculate inflorescences form inside leaf rosettes and emerge from the center.

Interesting! Flowering ends with the formation of fruits in the form of berries, which over time become capsules with seeds.

In home floriculture you can find only two varieties:

1. Yucca elephant or false palm looks like a shrub with pointed, elongated leaf blades. This name was obtained due to the trunk, which with age takes on the shape of an elephant’s leg. This is an unpretentious crop that grows in arid regions and is not attacked by various pests.
2. Yucca aloe vera is called that way because its leaves are shaped like aloe vera. Growing this variety requires effort and proper care. In an adult plant, the crown has a spherical shape, which is formed on a cylindrical volumetric trunk.

All varieties of yucca respond well to fresh air, so in the summer it is better to place it outside or on the veranda. The lighting should be intense, but diffuse.

Painful conditions

The tips of the leaves dry out

Florists have noted that the most common causes of yellowing and drying of leaf tips are:

1. lack of lighting in winter;
2. ear air.

Reduced daylight hours from October to the end of February, as well as cloudy weather, are factors that adversely affect the appearance of the palm tree. Yucca leaves lose color, stretch out, and turn yellow. Drying of the tips can be observed, sometimes accompanied by loss of leaf turgor. Phytolamps (any other artificial lighting) will help correct the situation.

Dry air during the heating season is the second common cause of drying out of the ends of the sheet plate. In winter, yucca should absolutely not be kept near a radiator or other heating devices.

It is important to take care of regularly humidifying the air in the room. Periodically wiping the leaves with a wet sponge will also help maintain the health of the palm tree.

Yellowing and drying of the entire plate

Yucca has a pronounced dormant period. In winter, the palm tree must rest so that in the spring it can begin to increase its vegetative mass with renewed vigor. Keeping the plant in a warm room, fluctuations in air temperature during ventilation, drafts, abundant and frequent watering do not allow the yucca to fully rest, and its immunity weakens. As a result, not only the lower leaves, but also the young rosette begin to turn yellow, lose turgor and dry out.

Correct conditions for keeping the plant in winter:

• consistently humid air;
• cool (10-15 degrees) without drafts;
• lighting about 10-12 hours;
• watering once every 2-4 weeks.

If the palm leaves are covered with dry yellow spots in the summer, the culprit is direct sunlight. Yucca received burns. The solution is to remove the plant to an area with diffused light or partial shade.

Leaves turn yellow at the stem

A situation often occurs when the leaf begins to turn yellow (or brown) from the base, gradually covering the entire plate. In this case, no drying is observed. The plant droops and withers.

This yucca has been in consistently wet soil for a long time and needs emergency replanting.

Common causes of the disease:

• spraying palm trees with a spray gun;
• keeping in a draft;
• waterlogging of the soil.

Frequent watering of the soil, especially during the dormant period, causes root rot, cracking of the stem and yellowing of the foliage. How to save the plant in this case? Remove the palm tree from the pot, remove rotten roots, and treat healthy ones with charcoal. Replant the yucca into new soil. Soil mixture for replanting: 1 part sand and turf soil, 2 parts universal substrate.

This measure will not help if the trunk has lost its elasticity and has become hollow inside. Then you will have to cut the yucca into cuttings and try to root at least one of the healthy areas.

Lack of microelements

Consequences of excessive watering and catastrophic lack of light

If the home conditions for growing yucca are close to ideal, but the plant still turns yellow, you should pay attention to the quality of the soil in the flower pot. The palm tree is clearly experiencing a lack of nutrients. What to do to return the yucca to its blooming appearance?

What to do to return the yucca to its blooming appearance?

First, it is necessary to establish what substance the plant needs. Secondly, choose one of the proposed options:

1. the palm tree can be transplanted into new enriched soil (during the period of awakening and active growth);
2. greens can be sprayed with a suitable composition according to the instructions (for example, iron chelate).

Table - diagnosis of plant condition

The whole plate dries out

Yucca has a characteristic dormant period. So, in winter the palm tree needs rest, because in the spring it will begin to intensively increase its vegetative mass. If you keep the plant in a too warm room, allow temperature fluctuations, drafts and abundant watering, the cause of yellowing of the leaf blades will not be a reason for the puzzle. All of the above negative aspects should be prevented.

During the winter season, caring for yucca at home involves:

• stably humidified air;
• lighting about 10–12 hours;
• cool (about 12–15 degrees) without draft;
• watering no more than once every 2–4 weeks.

If the leaf plates are covered with yellow spots in the summer season, ultraviolet radiation will have to be blamed. The plant turns yellow and dries out due to sunburn. The conclusion is that the palm tree should be removed to a place with diffused light or hidden in partial shade.

Symptomatic help if the ends begin to turn yellow and dry

A common cause of yellowing is improper maintenance conditions. Yucca is photophilous, but direct sunlight causes burns. Helping the plant is changing its permanent location. The plants also get stressed after transplantation. Rough replanting with damage to the root system leads to the dropping of the lower leaves. Yucca needs peace; 4 days in a dark place will help it cope with stress.

At this time, you need to maintain moderate watering, the root system does not absorb excess moisture. A good drainage system and light soil will help survive the stress of replanting.

Yellowed and wilted yucca leaves

Often a new place is not suitable for yucca. Slow growth and yellowness indicate an incorrectly chosen location for the plant. Rearrange and observe whether the appearance and speed of new leaves improves.

In the autumn-winter period, you need to remain calm: reduce watering, put it in a cooler place, but no less lit. In this case, the yucca will gain new strength and will actively grow in the spring.

Lack or excess of moisture, lighting, pests are the main factors affecting the growth and appearance of the plant.

Also, do not forget about natural shedding - this is a self-rejuvenation mechanism inherent in nature. The leaves live for two years and then die.

Yucca drops all its leaves after 2 years

Waterlogging of the soil

Yucca has a well-developed ground part, but the roots are less developed. Abundant, frequent watering leads to rotting of the root system and trunk of the plant. Watering is carried out with settled water at room temperature.

Leaves that are light at the base indicate waterlogging of the substrate; water the yucca less. Yellowed leaves on which brown spots appear are also a symptom of waterlogging of the soil.

It is necessary to dry the soil and loosen the top layer of soil. If this is not enough, replanting the plant will help.

During transplantation, the roots are treated with a fungicide solution. Disinfection will help cope with the fungus.

Brown spots on the leaves are definitely a fungal infection. Yellowed ones must be removed or cut back to healthy tissue. If the yucca's shoots have darkened, the plant cannot be saved; the root system and trunk have completely rotted.

Rotten Yucca trunk

Transplantation is carried out in a pot with a thick layer of drainage and large drainage holes. Rotten roots are cut off with a disinfected knife. The sections are treated with root growth stimulants. In case of severe damage, the plant is placed in water until roots form and then planted in the ground.

Low air humidity

Hot, dry air, especially in winter, when streams of hot air rise from the radiators and the air is dry, forces the yucca to fold its leaves into a tube and the tips dry out.

In its natural environment, yucca grows in Mexico, Central America and the southern parts of the United States in arid and warm climates. Low humidity is not a strong irritant, but in winter dry air is harmful, which is why additional humidification with a spray or steam humidifier is required.

Lack of lighting at home

Yucca in insufficient lighting conditions Light leaves, almost white at the base, the plant stretching upward is a clear lack of lighting.
If this happens in the autumn-winter period, the yucca needs to be additionally illuminated with fluorescent lamps. On a north window, an adult yucca suffers from a lack of light, this will lead to loss of appearance.

Small specimens feel good on all window sills. Yucca will feel good on a south or east window, but direct sunlight should be avoided. If the plant is mature, you can place the pot on the floor or on a special stand, then it will receive diffused lighting without the risk of foliage burns.

Soil drying out

Withered leaves that have lost their elasticity indicate a lack of moisture. After watering, the leaves become elastic again and do not turn yellow. A systematic lack of water leads to shedding of leaves and drying out of the root system. It is necessary to increase watering, the top layer of soil should dry out between waterings.

Low light

Often in winter the plant experiences a lack of lighting. During the rest period, this cannot harm him much. But if yucca is kept at room temperature even in winter, then during this period it continues to grow. If it doesn’t have enough light, it stretches out, its shoots become thinner, and its leaves turn yellow and droop. To prevent the yucca from losing its decorative effect and weakening in winter, you need to move it to the most illuminated southern window. Moving the yucca to a south window is not enough, and to increase daylight hours, you need to provide the yucca with additional electric lighting.

What to do for fungal leaf diseases

Overmoistening of the root system or general hypothermia leads to fungal infections. Dark spots on the leaves are a fungal disease caused by high humidity and excessive watering.

Another fungus that attacks the trunk causes stem rot. In the first stages, the fungus may not be noticed; in advanced cases, rot is detected too late, when the stem is affected, and inside it is filled with rot.

Fungus on yucca leaves

If the rot has not yet spread to the entire trunk, then the plant is cut back to healthy tissue and rooted. In advanced cases, it is disposed of along with the pot so that healthy people do not become infected.

Prevention lies in the correct selection of soil. Fine expanded clay, sand and coconut shavings should become faithful companions of the new soil; the soil will become softer and airier. Watering is moderate; between waterings the top layer of mail should dry completely.

Yucca is and remains a plant that does not require constant control. The right location is the key to active and healthy growth. Care and maintenance, periodic spraying, moderate soil moisture and fertilization will have a positive effect on the appearance.

View the full image Yucca belongs to the Agave family, although this plant is very similar to a palm tree. This family includes over 45 species, but no more than 7 species are cultivated as indoor decorative plants, and several more can be found in gardens and parks. Yucca is popular among gardeners due to its graceful trunk, the top of which is decorated with a mop of beautiful long leaves of emerald color. These evergreen plants come from North American countries. In its homeland, yucca is cultivated not only as ornamental plants. Yucca provides fiber that is used to make clothing, bags, ropes and baskets. And from the roots of the culture, local residents have adapted to extract natural red dyes, and parts of the plant are often used by traditional healers. Yucca leaves contain starch, so they are often used in cooking.

Spots on strawberries

Strawberries can have various spots, which can also lead to drying of the foliage and death of the bush. They are of fungal origin and arise due to improper care and the transfer of spores by insects.

Brown spot

Red-brown spots of uncertain shape appear on the leaves, as well as dark brown pads with spores on the reverse side, which gradually spread to flowers and fruits.

Strawberries are able to cope with pathology a little on their own, replacing dried leaves with young greens, but of a smaller size.

The peculiarity of fungal infection is that it is characterized by the presence of a dormant stage. Therefore, it is capable of manifesting itself several times per season.

It is useless to use folk remedies for such a lesion, so you will have to buy store-bought drugs. To prevent the development of brown spot, foliage and buds are treated with 1% Bordeaux mixture. In severe cases, Oxychom, Kuprozan, and Ridomil-Gold are used.

If brown spot occurs, it is necessary to reduce the amount of watering and refrain from fertilizing with nitrogen.

White spot

Spots appear on the leaves, which are initially dark red in color and round or oval in shape. But as it grows, a white point forms in the center of the formations.

When the disease is neglected, the spots begin to merge, and instead of light dots, holes form in the middle. The leaves turn red almost completely.

For preventive purposes, strawberries during budding and a month after picking the berries are treated with 1% Bordeaux mixture or Zineb, Falcon products. If the defeat is massive, use “Chorus”, “Strobe”.

The fungus spreads faster through the bushes with high humidity.

rust spot

The leaves are covered with small spots of yellow color, which quickly darken and acquire an orange-red color. Fungal spores accumulate on their reverse side, forming orange-colored pads.

All affected parts of the strawberries are cut off and then burned away from the garden plot. Then the bushes are sprayed with 1% Bordeaux mixture or the preparations “Titan”, “Agrolekar”.

Rust spot spreads quickly, so action must be taken immediately.

Brown spot

On the leaves of garden strawberries, round spots of red-brown color appear, distinguished by the darkest center. The formations are localized mainly at the main vein of the leaf. Sick plants quickly wither and then die.

Due to brown spotting, the gardener runs the risk of not getting a good harvest next year, since the bushes will not have time to gain the necessary strength.

Sick and drying bushes are pulled out and destroyed, and the soil in the beds is disinfected with Barrier strictly according to the instructions. The procedure is repeated after a couple of weeks.

Brown spotting is characterized by the fact that the spots stretch out over time, forming a triangle shape.

Black spot (anthracnose)

The defeat manifests itself in the form of dark ulcers on the petioles. The leaves begin to brown and small spots form on them. As they grow, they turn black. The disease gradually spreads to flowers and fruits that dry out. Then the blackening plant dies completely.

For anthracnose, such remedies as “Skor” and “Fundazol” help. To prevent the development of the disease, spray with “Fitosporin” and “Gamair” at least 3 times per season.

If the bushes have turned black, it is recommended to add some kind of biostimulant to the solution, for example, “Zircon”.

Bushes that suffer from a deficiency of useful components or have any damage are especially susceptible to the disease.

How to revive yucca

Reviving an indoor flower can be difficult, but in the initial stages the simplest measures are sufficient.

What to do in order to save the yucca:

1. Try to determine the exact cause of the yellowing.
2. Create a favorable microclimate corresponding to the growing season.
3. If the leaves droop due to a clear lack of moisture, add a small amount of warm water and repeat the operation after a couple of hours.
4. If necessary or when it is not clear what caused the problem, transplant the bush into a new substrate.
5. Carefully inspect the root system and remove rotten roots. If pests or rot are found, wash with an appropriate preparation. Treatment with Epin or Zircon will help restore roots in a shorter time.
6. Feed only in case of obvious lack of nutrition, but after transplantation, postpone the procedure for a couple of months.
7. Fungal infections are treated with fungicides; insecticides help get rid of pests.

What to do to save thuja from drying out

Take a pruner and ruthlessly clear the plant of dry, reddened needles. It will not fall off on its own, and the tree will never be cleansed. Pruning with confidence. Sometimes the “final” tree looks terrible, having lost half of its needles.

1. Cut off the growing point (shorten the crown of the plant by 10-15 cm).
2. Buy acidic peat (with a pH of 3-4) and spread it in a thick layer under the plant. Mix the peat moss into the top layer of soil.
3. Apply “Buyskoe coniferous” fertilizer together with peat - the norm is 20 g per plant.
4. In the spring, spray the needles with diluted Epin, ten days later - with Zircon, after another ten days - with mullein (dilute 1/2 cup in 5 liters of water).
5. Admire the result - a partial recovery will occur by the end of summer. The needles will turn green and grow vigorously.

To prevent the thuja from drying out and to look great, it is necessary to spray it with a solution of “Zircon” or “Epin” for prevention. Spray generously so that the needles drip.

You need to know the enemy by sight

In addition to diseases, some insects are enemies of yucca. Pests rarely attack a plant with strong immunity, but diseased, depleted specimens often become their target. Let's consider who can live with your pet.

Mealybug

Most often it affects a palm tree in the off-season, when the plant experiences stress from changes in temperature. Externally, mealybugs look like small cotton balls; if you crush the fluffy ball, bloody discharge appears. Its harm is enormous, since it sucks juice from leaves and branches and multiplies very quickly.

If you notice a mealybug infestation, thoroughly wipe the yucca leaves with a sponge dipped in warm, soapy water, removing all visible traces of the pest. After this, treat the plant with an insecticide (Aktara, Calypso, Fitoverm, etc.). The procedure must be repeated 3-4 times with an interval of 7-10 days.

Shchitovka

Another dangerous enemy of yucca is the scale insect. A tiny insect, similar to a small turtle, is generally mistaken by some for a growth on the leaves, since it is motionless. Having firmly attached itself to a leaf blade or cuttings, the scale insect sucks out the juices of the plant. The first sign of a dangerous neighborhood is a sticky, shiny discharge.

Not only the scale insect itself harms the flower, but also the sticky substance. It clogs the pores of living tissue, creating favorable conditions for fungal infections.

The “shell” of the scale insect is so dense that it is difficult to kill it even with chemicals. First you need to remove adult individuals mechanically - with a swab moistened with a concentrated soap solution or vodka, clean the leaves and stems of brown “growths”. Remove the top layer of soil.

After this, treat the plant with an insecticide. As with mealybugs, repeat the procedure at least 3 times.

Spider mite

Spider mites can settle on weakened plants. First, light “grains” appear on the back of the sheet, and then a thin web appears.

To combat the pest, you will need an insecticide with an acaricidal effect - Fitoverm, Vertimek.

In addition to diseases and pests, there may be other reasons why yucca leaves turn yellow - we have a detailed article about this.

To increase the plant’s resistance to stress, do not neglect feeding in the summer - a balanced diet will help build strong immunity. In winter, give the yucca a rest and gain strength for the new season. Proper care is the best disease prevention.

A video about caring for yucca will help you avoid many problems.

Diseases and pests of yucca

Yucca reacts painfully to many factors:

1. Watering with cold water.
2. Drafts.
3. Excessive watering.
4. Soil hypothermia.
5. Root damage.

Excessive soil moisture combined with low temperatures can lead to rotting of the roots, and this, in turn, to the death of the plant. First, the leaves wither and fall off. If the cause is discovered in time, you need to remove the plant from the ground, remove damaged areas, and treat them with a disinfectant. When the cutting area dries out, plant the plant in the ground. But it is better to choose a more suitable area for this.

Root rotting is often combined with the appearance of yucca pests:

• Mealybug
• Spider mite
• Shchitovka

You need to fight pests by treating yucca with one of the insecticides (Aktara, Karbofos). Iskra BIO will help you get rid of spider mites. But first, before purchasing an insecticide, you need to treat the affected areas with a solution of laundry soap.

What does the poor appearance of the plant indicate:

• The ends of the leaves turn brown from too dry air or drafts. This may also indicate that the plant needs watering. Light, dry spots indicate sunburn. Curled leaves indicate that the yucca is cold. You need to determine the cause and eliminate it.
• Anthracnose is a fungal disease. Brown spots with a yellow border appear on the leaves. The edge of the spot is convex. As the disease progresses, they merge into large ones. High humidity promotes the appearance of anthracnose. Prevention in the apartment: do not spray the leaves, reduce the air humidity in the room. Treat with antifungal drugs (“Folli”). In the garden, they are treated with Saprol antifungal drugs, weeds are removed, and the vegetation around is thinned out so that air can pass freely between the leaves. Spill the soil around the plant with a solution of Fundazol. If the measures taken do not help, then it is better to remove the plant.
• Sometimes a white coating forms on yucca leaves. Young leaves are especially susceptible to the disease. This occurs due to damage to the plant. This is a fungal disease, so the methods of dealing with it are the same as with anthracnose. You can spray the plant with “Skor” and “” preparations at intervals of a week.

The result of the fight against the disease can be judged by the further development of the plant. If the growth that appears some time after treatment is healthy and beautiful, the treatment was effective. If it is also affected by powdery mildew, it will have to be pruned. Most often this helps to get rid of the disease. In severe cases of fungal infection, the plant stem may soften. In the initial stage, you need to remove the diseased areas and treat the cut areas.

Indoor yuccas can develop fungal diseases:

1. Gray rot, which affects leaves and stems.
2. Cercospora - brown spots on the leaves, merging into one, with a light center and a dark edge.
3. Yellow mottle is a viral infection of leaves that appears as small yellow spots. They are located closer to the end of the sheet. The appearance of the disease is facilitated by aphids that carry the virus. Affected plants are dug up and burned.

Do not cut off wilted leaves from a healthy garden yucca plant. This may result in the plant not blooming. Purchased indoor yucca may shed its leaves. This is due to stress after moving. After a couple of weeks, the leaves will begin to grow. Yellowing of the lower leaves is a natural process. 2 years after formation, the leaf turns yellow and falls off.

Very often, when growing yucca, gardeners are faced with yellowing and falling of the leaves of this plant. Its leaves dry out at the tips, and then the leaf blades die off completely.

But if it is rapidly losing leaf mass, it is necessary to look for the reason in improper care of this palm tree.

Yucca can lose leaves due to poor or abundant watering, too dry air and insufficient lighting. Also, the leaves may dry out and turn yellow if the plant is damaged by pests.

Common Yucca Diseases

Most diseases of yucca are associated with improper maintenance - waterlogging of the soil, depletion of the soil mixture, and, consequently, weakening of the plant's immunity. But it happens that the infection enters from the outside, for example, with the substrate or other indoor flowers. What problems most often arise with palm trees?

Fungal infections affecting the crown

Several groups of fungi manifest themselves by infecting yucca leaves. All sorts of spots, yellowing, and sores appear on them. If you don’t catch it in time, the spots increase, merge, and eventually the leaves dry out and the plant itself droops. We’ll tell you how to revive it at home using the example of several diseases.

Cercospora is an infection caused by a fungal pathogen (Cercospora)

A favorable environment for this fungus is high humidity. It occurs due to constant overflows, as well as when the grower gets carried away with spraying plants. Round spots of light brown color with a dark border appear on the leaves, which gradually grow, affecting new areas.

Having noticed the disease, first of all remove the affected leaves as much as possible.

Then treat with a systemic fungicide, first a “light” one (Fundazol, Topaz). The number of sprayings is 2–3 times with an interval of 10 days.

And, of course, it is necessary to eliminate the factors that led to the yucca disease - dry the earthen ball, reduce watering, stop spraying the crown.

Brown spot

The causes of the lesion are similar to the previous disease, but are caused by a fungus of a different group. It primarily affects the lower (old) leaves. First, discolored areas appear, then they turn yellow, and after 3–4 months they become brown. At this time, you can notice fungal spores located in the center of the spots.

Control measures are the same as for cercospora. If the disease has progressed, you can use a stronger fungicide, for example, Ridomil Gold.

Why might pumpkin leaves turn yellow?

Yellow leaves on a pumpkin do not always indicate that a disease has appeared on the crop. In some cases, this indicates that the plant is not being properly cared for or is lacking nutrients.

The leaves begin to turn yellow if the heat gives way to a sharp cold snap. For plants, such a sharp temperature change is stressful. Prolonged heat or prolonged cold weather also causes foliage to dry out. At low temperatures, the leaves freeze and turn yellow. During drought, the foliage on the pumpkin begins to dry out from burns caused by bright sunlight. Bushes get burned due to improper watering.

When the foliage turns yellow, it indicates that the pumpkin is lacking micronutrients. Primarily nitrogen, magnesium, potassium or other substances. You can minimize the damage if you take the time to care for the pumpkin.

Impact of temperature

An alarming signal when growing a false palm at home is if the leaves of the yucca curl .

Low temperatures have a detrimental effect on the life of the plant, because it comes from the subtropics and absolutely cannot stand the cold.

When exposed to low temperatures, the leaves become brownish at the edges and gradually curl up. There are times when the temperature drops at night and the sensitive yucca freezes overnight. In winter, it is better to remove it from the windowsill in the evening until the morning, until it gets warmer.

With severe hypothermia, foliage can fall off en masse. The false palm tree does not tolerate drafts well. It is better to take care in advance that the flower is warm and cozy, especially in winter. Read how to insulate yucca for the winter here.

Why do cucumber leaves turn yellow?

In most cases, yellowing of leaves occurs due to violations of agricultural cultivation techniques, the development of diseases, a lack of microelements in the soil and damage by insect pests.

Other mistakes when caring for yucca

The practice of cultivating indoor yucca has shown that the palm loses its attractiveness on northern windows. The plant turns pale, stretches, withers, and gets sick.

Brown dry tips appear in the event of a SYSTEMATIC lack of moisture in the yucca during the hot summer period. Here we must learn to “pour in moderation.”

Dry air is the cause of spider mites. White fluff from the bottom of the leaf, yellow spots are evidence of the work of an insect pest. It is necessary to wash the plant under water and treat it with insecticides.

In winter, the brown edges of the leaves signal that there are drafts moving around the apartment.

In conclusion, I would like to note that, despite possible problems, indoor yucca is considered an unpretentious and easy-to-care plant. As a rule, palm trees do not cause trouble for owners.

Improper care

Improper care is one of the reasons why grape leaves turn yellow, dry out, curl, crumble, or do not grow at all.

Firstly, this can happen due to excess or deficiency of nutrients. For full growth and development, grapes simply need fertilizing, but their amount must be balanced, otherwise many problems may arise. So, if there is a lack of essential microelements, the plant will slow down in growth, drop flowers and ovaries. Its foliage will be deformed, the plate itself will be covered with small spots, which will begin to increase in size over time. If we talk about specific minerals, their deficiency manifests itself as follows:

• with potassium deficiency, the grape leaf begins to bend outward;
• lack of phosphorus leads to darkening of green veins;
• if there is a lack of nitrogen, the foliage dies;
• if the plant lacks sulfur, magnesium or zinc, this leads to yellowing of the foliage.

To correct the situation, it is enough to simply feed the plant: for example, to compensate for the lack of nitrogen, grapes can be sprayed with potassium sulfate during flowering.

Secondly, problems can arise due to improper watering, because water is also important for the normal development of grapes. The plant may simply not have enough water or, on the contrary, there may be an excess of it.

To correct this problem, it is important to monitor the condition of the plant, and also take into account weather conditions: for example, at high temperatures, it is recommended to water once every 7 days. To prevent water from stagnating, the soil needs to be loosened, and to prevent its active evaporation, it is recommended to mulch

Thirdly, frosts can also cause problems, from which the plant must be saved. Otherwise, the foliage of the plant will deteriorate and its color will become more faded. To get rid of problems, it is imperative to protect the plant from frost and also mulch the soil.

Fourthly, yellowness can also be caused by excessive planting density. This usually interferes with the circulation of air masses. A large number of shoots prevents the penetration of sunlight, which ultimately leads to disruption of the photosynthesis process. Subsequently, the color of the grape leaves begins to become distorted. Fixing this problem is not difficult: you need to regularly trim off excess branches.

Prevention measures

Creating a favorable microclimate and proper care will protect the yucca from yellowing and other signs of ill health. It is necessary to ensure suitable humidity, temperature and light conditions, and avoid excessive watering. An indoor flower can be placed on any windowsill, but should be slightly shaded when exposed to direct sunlight.

When it gets warmer, it is advisable to take the plant out into the fresh air, gradually increasing the time spent on the street or balcony. In this case, it should be protected from precipitation.

It is important to periodically inspect the leaf blades for signs of pest infestation. In summer, wipe the leaves with a damp soft cloth

Transplantation is carried out once a year in the spring. Feed once a month with complex formulations.

Growing yucca at home rarely brings any inconvenience, since the crop is unpretentious, requires minimal care, and is decorative all year round. When exposed to unfavorable factors, the tips of the leaves dry out, the leaf blade turns yellow, becomes stained, and curls. To protect the bush, it is necessary to establish the cause in time and take action.

Yucca is a very beautiful plant that looks like a lush palm tree. Yucca grows extremely slowly, but can eventually reach almost 4 meters in height, so it requires quite a lot of space.

If the leaves of this plant suddenly turn yellow and dry, this indicates errors in care, which in the future can even lead to the death of the plant.

Let's take a closer look at the questions: why do yucca leaves turn yellow and what to do if the leaves dry out and lose their healthy appearance.

Causes of yellow leaves

Yucca is an evergreen plant, so the leaf cover does not change every year. However, the leaves gradually age, die and are replaced by new ones. So don’t be surprised or alarmed if some of them begin to turn yellow and dry out in the lower part of the plant. This is a natural and completely normal process.

However, intense leaf fall throughout the tree indicates some problems with its health or living conditions. Let's look at them in detail.

Lack of light

In nature, yucca receives a lot of sunlight. In the Russian climate in winter it is not enough for the plant. As a result, the leaves turn pale, become limp and yellow. The solution to the problem is to increase the duration of daylight hours to 10-12 hours using artificial lighting.

You can purchase special phyto-lamps or install regular ones. But there is an important nuance - they should not get very hot. This is dangerous due to leaf burns and drying of the air in the room.

The air is too dry

Monstera is a resident of arid areas, so it does not need high humidity. But the Russian climate, combined with the heating season, can make the indoor air too dry even for her. In this case, the leaves begin to turn yellow and dry out.

• Remove the pot away from the radiator or other heat sources.
• Raise the humidity level.

Installing a special electronic humidifier, containers with water, periodically wiping the leaves with a damp sponge or spraying the tree with a spray bottle will help.

Please note: you should spray not so much the plant itself, but the space around it. If there is too much water on the yucca, it will begin to accumulate in the axils of the leaves and lead to their rotting.

No rest period

In winter, yucca “rests” and gains strength before the new growing season. During this period, it is undesirable to expose the plant to any stress or changes in conditions. Otherwise, her immunity weakens, her strength decreases, and not only the old leaves, but also the young rosette begin to turn yellow and wither.

If, out of ignorance, you have violated the dormant period, try to create a comfortable and stable regime of watering, temperature and humidity for the plant as quickly as possible, and eliminate drafts. Unless absolutely necessary, do not move the pot or replant the yucca.

Excessive humidity

This reason can be diagnosed by the fact that yucca leaves turn yellow and wither, but do not dry out. Waterlogged soil or too much water spraying can harm the plant. If the plant is in a draft, the situation will worsen even more.

Whether the yucca can be saved will depend on its condition. If most of the root system and trunk with leaves have rotted, it is easier to throw out the plant. If only a few leaves are affected, they need to be cut off and watering or irrigation of the yucca should be reduced accordingly.

Nutrient deficiency

With yellow leaves, yucca often signals another problem - soil depletion. No matter how nutritious it may initially be, the plant gradually draws out everything valuable from there.

To compensate for the deficiency of microelements in a pot with yucca, you can completely change the soil, for example, during the next replanting. The second option is to add complex fertilizers containing iron, magnesium and nitrogen to the soil.

Tip: For indoor plants, fertilizers are best used in the form of weak solutions. This will help avoid burns to their root system.

Rough transplant

Changing the yucca pot should be done carefully, trying not to damage either the roots or the above-ground part of the tree. Otherwise, the plant will experience severe stress, which will be demonstrated by yellowing and dropping leaves. Usually, after some time, the yucca will adapt and throw out new healthy leaves.

But to speed up the process, you can feed it with a root growth stimulator. This will provoke their restoration and activation of green mass growth

Watering against yellowing

Both garden and indoor yucca do not tolerate very infrequent watering. But in the same way it does not tolerate excess moisture. This houseplant is considered a succulent that creates a water reserve in the stem. This helps the palm tree to get through the dry period without loss. At home, succulents need abundant, but still infrequent watering.

If you water your yucca incorrectly:

• water rarely - the plant withers and dries out, the leaves quickly turn yellow and die;
• If you water excessively, the roots of the plant will turn sour, as moisture stagnates in the soil.

Roots damaged by excessive watering cannot cope with their functions; they are unable to provide the yucca with moisture and valuable microelements, so the shoots turn yellow, the leaves wither, and stretch down.

In summer, watering should follow after the top layer of soil in the flowerpot has dried. In winter, the earthen ball must dry completely between waterings, since the plant is in a state of rest (or, as gardeners say, “hibernation”). A sign of excess water is darkened tips of the leaves, as well as a limp trunk.
