How to provide proper care for alocasia at home

Alocasia is an exotic ornamental foliage plant. A bright representative of the aroid family. Many varieties of this species differ from each other in color, shape, leaf size and dimensions. This plant appeared in indoor floriculture relatively recently - no more than 10 years ago, and some varieties are considered young and rare; flower growers dream of getting them into their collection. The plant has a bright appearance and is considered relatively unpretentious. it is often used for interior landscaping.

About the plant

Alocasia is a large, evergreen, herbaceous plant. As a rule, it has a developed aboveground stem, covered with scars - leaf traces of dead leaves. Young plants have a shortened stem. At the top of the stem there are several very large oval-arrow-shaped leaves.

Its leaves are thick, dense and almost leathery. Leaf blade with thick veins protruding on both sides; leaf petioles are long, succulent, with a long sheath. With good care, the plant develops 6-7 leaves, and the size of the leaf blades can reach 50-80 cm in length.

On a note !!!

The leaves have aqueous stomata-hydathodes, through which droplets of water are released in wet weather or when overwatered.

Sometimes it blooms in summer. The flowers are very small, collected in a spadix, equipped with a large light cover.


Alocasia flower

Alocasia is a fairly unpretentious plant that requires regular but simple care. It grows well in warm and humid microclimates. If you provide your tropical beauty with conditions close to natural, then she will delight you with her exotic beauty.

On a note !!!

If the leaves on an alocasia periodically turn yellow and disappear (one at a time, and not all at once), this is a normal process - a new one is already growing in place of the missing one.

How to properly care

Alocasia is suitable for indoor conditions. The plant can be placed on a windowsill, but the leaves must be protected from direct sunlight.

Landing

Immediately after purchasing the alocasia, you can plant it in a larger pot and add fertile soil. The best time for planting is spring. True, a plant purchased in winter can also be planted in a new pot. Adaptation will just be more painful.

Soil requirements

Alocasia needs slightly acidic and fertile soil that will allow moisture to flow well into the pan and dry quickly. The base is leaf or turf soil. Peat, sand, vermiculite, pieces of bark, chopped moss and a little humus are mixed into it.

Selection and arrangement of a pot

In alocasia, the roots grow not in breadth, but in length. The plant needs a deep but narrow pot. It would be better if it were ceramic. There should be a drainage hole at the bottom. A little expanded clay is poured into the pot for drainage, then the roots of the plant are sprinkled with the prepared soil mixture.

How to plant

The transshipment method is not suitable in this case

The plant, along with the earthen lump, is carefully removed from the pot, and then the roots are cleared of soil. This procedure is carried out to thoroughly examine the roots to see if there is any rot on them.

Before planting, the plant can be placed in water with a growth stimulator for 30 minutes. Then the alocasia is placed in a pot and covered with soil. The root collar should be above the soil surface.

Bloom

Alocasia blooms very rarely. An adult and fully formed plant produces an ear in spring or summer. Flowering lasts only 5-12 days. During this time, the plant manages to shed almost all its leaves. After flowering, alocasia regains its strength for a long time. If you cut off the flower stalk at the very beginning, the plant will not lose leaves.

Temperature and light

In the room where the alocasia is located, the air temperature should be 20-25 degrees Celsius. In winter, the thermometer can drop to 16 degrees above zero. At lower temperatures, the plant will begin to shed its leaves. A short stay in the cold can completely destroy this heat-loving crop. In summer, the plant gets enough sunlight. In autumn or spring in the evening it can be illuminated with a fluorescent lamp.

Air humidity

This tropical plant with large leaves loves a moist environment. Air humidity should be 70 percent.

Spraying

In hot weather, alocasia leaves should be sprayed 2-3 times a day. The water is sprayed in the form of a mist rather than droplets. In winter, this procedure can be performed less frequently.

Watering mode

Alocasia is watered abundantly, but so that the water does not stagnate in the pot for a long time, otherwise the roots will begin to rot. Watering is carried out every other day. The soil should always be moist, but not swampy.

Feeding and fertilizer

In the spring, when the period of active growth begins, the plant begins to be fed with nitrogen, phosphorus and potassium substances. A small amount of universal fertilizer is added to the water for irrigation twice a month until the fall.

Transfer

Once every 2-3 years, alocasia is transplanted into a larger pot. Drainage pebbles are placed at the bottom, and the rest of the container is filled with slightly acidic soil. Alocasia, along with a lump of earth, is removed from the old pot and transplanted into a new one.

This plant does not need any pruning. You can only trim off yellowed and dried leaves. True, they should turn yellow one at a time, and not all at once. A healthy plant sheds old leaves gradually, so it renews itself.

Alocasia: lighting

Alocasia is a light-loving plant, but it needs to be shaded from direct sunlight. The best location for the flower will be windows facing east. The flower will feel comfortable on the western side, but in the south its leaves will wither. In this case, as mentioned above, shading will be required.

But even if protected from bright sunlight, alocasia should not be severely oppressed. In this case, dark spots may appear on the leaves and there is a risk of the plant wilting. The color of the foliage may also change.

Some types of alocasia, in particular copper-red and Amazonian, require additional lighting in winter.

Varieties

Dragon Scale is the common name of the species. However, depending on the shade of the leaves, two varieties are distinguished.

Alocasia Silver Dragon

It is distinguished by silvery leaves and dark veins.

Alocasia Pink Dragon

A rare variety with dark leaves, light veins and pink stems.

It is interesting that the cost of these varieties in different stores and garden centers can vary dramatically, but the “pink dragon” always costs more.

Alocasia: watering and air humidity

Abundant in summer, the soil should never dry out. Water frequently with soft, settled water so that the soil in the pot is constantly moist (it is advisable to immediately drain the water from the pan). In winter, watering alocasia is moderate and very careful. For most species, overwatering leads to root rot.


Watering Alocasia

Alocasia loves high humidity. In hot summer weather it needs spraying. To create additional air humidity, you can place the pot with the plant on a tray with wet expanded clay or pebbles.

Alocasia: soil

Alocasia loves nutritious, loose and breathable soil with a slightly acidic alkaline environment (pH about 5.5). Mixtures of the following composition are well suited for planting:

  • humus, leaf, turf soil, peat and sand in a ratio of 2:2:2:1;
  • leafy, coniferous soil, peat, sand in the ratio 1:1:1:0.5;
  • leaf, peat soil, crushed sphagnum, sand (2:1:0.5:1).

You can plant alocasia in a ready-made store-bought mixture intended for indoor plants.

In a good soil mixture, the plant exhibits all its decorative qualities. It grows and blooms well.

Alocasia: feeding

Fertilizer. In spring and summer, alocasia requires feeding every 2-3 weeks. It is best to use complex mineral fertilizer for indoor plants. Organic matter should be added carefully, as it contains a large amount of nitrogen, which can cause rotting of the flower, leaves and stem.


Fertilizers for alocasia

It is best to alternate feedings. For example, foliar feeding is applied first. Here liquid fertilizer is used for decorative deciduous plants. It is distributed over the leaves. After 14 days, the plant is watered with a solution containing mineral fertilizers. Mineral fertilizers can not be diluted in water, but used in dry form. Several granules, about 7-8 pieces, are placed on the ground after watering the plant. They gradually begin to melt and with each watering, along with water, they fertilize the soil.

Important!!!

Fertilizing should be used only in the recommended proportions, because an excess of fertilizers is no less dangerous for the plant than a deficiency.

When foliar feeding, not only ready-made liquid fertilizers are used, but also the HB-101 preparation, biological additives, and chelates.

Medicinal properties

Despite the fact that shamrock is poisonous, its medicinal properties are widely used in Chinese folk medicine. You just need to strictly follow the dosage so as not to harm the body.

Leaves treat pneumonia and tuberculosis. The stems help relieve stomach and toothache. The juice relieves pain and invigorates the body. Alocasia can suppress cancer cells.

It is not advisable to treat yourself in this way, so as not to get poisoned, but you are quite capable of placing a flowerpot near the patient’s bed when he has a cough or fever. Only it should be a large-rooted alocasia. This species has healing properties.

Be sure to have this amazing plant with unusually beautiful leaves at home. If you try a little, the weatherman will feel at home in your apartment, just like in wildlife.

Alocasia: transplant

The soil for alocasia must be nutritious. For good growth, you need a substrate that is well permeable to moisture and air and has a slightly acidic reaction (pH about 5.5).


Alocasia transplant

Replanted annually, usually in early spring, mature plants after two years, soil:

  • 1 part leaf soil;
  • 1 part coniferous;
  • 1 part peat;
  • 0.5 parts sand.

An earth mixture made up of sand, garden soil and greenhouse soil in equal parts is suitable.

On a note !!!

For large specimens, replanting can be replaced by transferring it to a pot of larger diameter. It is better to take tall pots. Good drainage is necessary.

Alocasia: reproduction

Alocasia can be propagated in different ways: by seeds, dividing the rhizome, suckers or daughter tubers, and stem cuttings.

Alocasia from seeds

Alocasia with variegated leaves cannot be propagated by seeds - variegated leaf characteristics are not expressed. Sow the seeds immediately after collection, shallowly in a light substrate (leaf or peat soil and sand). To ensure high humidity, cover the top with glass or film. Temperature 22-24°C and regular spraying. The seedlings are picked and then transplanted into small pots. Large leaves appear after a year.

Alocasia offspring and daughter individuals

It is much easier to propagate alocasia by offspring or daughter tubers. When dividing the rhizome and preparing stem cuttings, do not forget to sprinkle the cut areas with charcoal. For rooting, the substrate is the same as for sowing seeds. You can cover the planted cuttings with film.


Reproduction of alocasia

Reproduction by cuttings

To do this, a bud is cut out from the stem of a large specimen along with the pulp adjacent to it. The surface of the cuts is sprinkled with crushed charcoal and placed in sand or a mixture of peat soil and sand, leaving the bud above the surface of the substrate.

Alocasia: pests

The most common pests of alocasia are aphids and spider mites. In addition, it is affected by mealybugs and scale insects. Dry air and high temperatures promote the appearance of pests. If pests are detected, if the infestation has not gone far, carefully wipe the leaves and stems with a soapy sponge. In case of severe damage, you can use Actellik solution (1-2 ml per liter of water) or another similar remedy.

Attention!!!

All organs of alocasia contain toxic substances, so you should be careful when caring for the plant, and wash your hands thoroughly after work. It is not suitable for landscaping children's institutions.

Alocasia, distinguished by its splendor and exotic beauty, is deservedly recognized as one of the most outstanding foliage and ornamental plants. Powerful specimens, reaching several meters in height, are a rich decoration of the interiors of public spaces: bright halls, foyers, rest rooms. Widely used in the creation of winter gardens and the design of artificial ponds and fountains. Only small young plants are suitable for keeping in rooms.

Prevention of various problems

Over time, the leaves inevitably turn yellow, but if green veins remain on them, and then they gradually dry out, this is a natural aging process. You just need to cut off such leaves. But if only the upper leaves turn yellow and dry out, this means that the air is too dry for the plant; you need to spray the alocasia with warm water more often.

If young leaves practically do not appear or grow small, this indicates that the plant requires feeding.

Alocasia Dragon is a beautiful indoor plant that will fit perfectly into any interior. The main thing is to follow all the rules for caring for it.

Possible difficulties

When growing alocasia, you should pay attention to the following difficulties that gardeners usually encounter when growing this plant:

  • Alocasia has stopped growing. This situation arises for two reasons: either the plant needs replanting or is experiencing a deficiency of minerals. The solution here is very simple; the flower needs to be transplanted into a larger pot or, if the container is normal for the plant, fed.


    Alocasia diseases

  • Alocasia leaves wither. This problem occurs when the soil is excessively waterlogged. It can also occur when the earthen lump is very dry. In this case, it is enough to adjust the watering. If, even after normal watering, the leaves continue to wither, it means that the soil in the pot is too dense. In this case, you should change the soil to a looser and more breathable one.
  • Alocasia leaves have turned pale or changed color. This situation occurs with aging and dying leaves. In place of the old fallen leaves, after a certain period of time, new leaves grow. The drawing on the sheet may fade due to lack of light.
  • The tips of the leaves dry out and turn black. The reason is lack of watering, low light, low air humidity.
  • Dark spots have appeared on the leaves of Alocasia. There may be several reasons: drafts, hypothermia, too dry or vice versa, damp soil, overdose of fertilizers. Dark spots sometimes appear due to mechanical damage, waterlogging of the soil and excessive application of nitrogen fertilizers. This situation often leads to the occurrence of fungal and bacterial rot. In this case, the rotten place is treated with fungicides or the plant is transplanted into new soil.
  • Rotting of the rhizome. This problem occurs when the room temperature is low, there are drafts, and the plant is flooded so that the soil does not have time to dry.
