Proper care of alocasia

Alokazia requires special attention so that it retains its aesthetic characteristics for a long time. Given that the plant is native to the tropics, care must be taken to create a suitable microclimate for it..

Lighting

Good diffused illumination is preferable for alocasia. She is afraid of direct sunlight, as they often cause leaf burns, manifested by spots. This must be taken care of when planting – if the culture is planted in open ground, it will need partial shade at midday, and it is better to locate household residents in the back of a room with windows facing east or west. Additional lighting is required in winter.

Temperature

Alocasia is thermophilic enough. The optimal mode fluctuates in the range of + 22 … + 27C in the warm season. In winter, do not lower the temperature too much, the culture will feel comfortable at + 15 … + 18C, which is not at all difficult to provide at home.

Humidity

The plant is very fond of a microclimate with high humidity up to 80%. For garden specimens, in addition to regular watering, it is necessary to spray. In a closed room, it is more difficult to maintain this level – you can install flowerpots over containers with wet expanded clay so that the flowerpot does not come into contact with moisture, otherwise the root system will rot. In the heating season, a container with water is installed next to the alocasia. As well as garden, indoor plants require systematic spraying, and the leaves can be additionally wiped with a damp sponge..

Watering

In the spring-summer warm period of alocasia, frequent abundant watering is required, which decrease by autumn. In hot weather, the plant must be watered as the top cover of the soil dries up, and in winter, once a week is enough. You can alternate watering with irrigation. It is very important not to overdo it with drinking, as waterlogged soil can cause great damage to the roots. To avoid such unpleasant consequences, even at the planting stage, it is necessary to lay a thick layer of drainage material (for example, expanded clay).

Fertilizers and feeding

To maintain the decorativeness of the culture, it is necessary to fertilize it. Room dwellers are given complex fertilizing twice a month, containing a high level of potassium. After transplanting, the first feeding is carried out in a month. You also need to fertilize alocasia during the growing season and at the end of the flowering period..

Diseases and pests

Quite often, improper care becomes the cause of alocasia disease. For example, insufficiently humid air in the room contributes to the drying of the edges of the sheet and the appearance of brown spots. In almost the same way, sunburn on the leaves appears when the plant is in direct sunlight for a long time. Waterlogged soil can lead to root or stem rot. In such cases, it is necessary to immediately establish proper care..

Also, the danger is represented by diseases such as:

– Fusarium, the signs of which are putrefactive spots first on the petioles, and then on the leaves, as a result of which they die off. In this case, it is necessary to cut off all damaged parts, including the root system, wrap the trunk with wet moss and cover the plant with foil. When new roots appear, it is transplanted into new soil;

– Anthracnose, characterized by the appearance of brown spots with a yellowish edging, which expand over time. Here you can not do without fungicide treatment;

– Powdery mildew is defined by the presence of white-yellow or black spots on the foliage. In case of infection, it is necessary to remove damaged leaves, treat with fungicide and take care of.

Alocasia can also suffer from insects that enter through the soil or from neighboring plants. The most dangerous are scale insects, nematodes, aphids and spider mites. You can recover from them by treating the plant and soil with insecticides..

How to transplant alocasia

The transplant is carried out in the spring. The capacity should be high, as the roots of the flower stretch inward. River sand, bark or coconut flakes must be added to the soil mixture to make it looser. Drainage must be laid at the bottom of the pot, the layer of which can be a third of the height. Alocasia should be placed in a pot, sprinkled with soil, lightly tamped and watered abundantly. This is followed by the usual care.

Reproduction at home

There are a fairly large number of ways how to propagate alocasia: by planting seeds, dividing, leaves, cuttings or root children. The choice largely depends on the type of a particular plant. Regardless of how exactly this will happen, there are a number of rules concerning any of the processes, namely:

– The bottom of the planting pot must be covered with drainage, including crushed coal, broken brick;

– The soil for plant development should be light, with a low acidity content;

– The soil for planting must be disinfected;

– Saplings need to regularly moisten the soil;

– Any planting material, with the exception of seeds, needs to be cut with charcoal;

– To accelerate the formation of roots, children, cuttings and leaves must first be soaked in a solution-stimulating root formation.

The best time to start the reproduction process is considered to be spring, when any plant is gaining the greatest biological activity, but if necessary, you can start in summer or autumn..

Reproduction of alocasia by seeds

This method is used much less often and is explained by the fact that the seeds must be sown only when they are in the berries – moist shells. But, given that in the conditions of apartments and houses, alocasia blooms quite rarely, it is difficult to get material.

If, nevertheless, there are seeds, they must be placed on the surface of the prepared soil and, without immersing deeply, slightly compacted. Then the bed is moistened using a spray bottle and covered with plastic or glass. The sowing is ventilated and moistened daily.

In two to three weeks, the first shoots will appear. Transplantation to a permanent residence is carried out with the appearance of a pair of full leaves.

Reproduction of alocasia by leaves and cuttings

Using the deciduous method, cut off a young leaf, dry it a little, and then, after making another small cut, place it in a pot with soil. At this stage, it is necessary to create greenhouse conditions where humidity and temperature will remain, therefore, the planting is covered with a glass jar or a plastic bottle..

Every day, the cover must be raised to ventilate the greenhouse and moisten the soil. With the eruption of the second leaf, the cover is removed, and the young plant is provided with the usual care.

The process of grafting is carried out in absolutely the same way..

Reproduction of alocasia by dividing the rhizome

In the spring, you can propagate alocasia by dividing the root. To do this, the flower must be carefully removed from the pot, rinse the rhizome, freeing it from excess soil. The incision is made with a sharpened knife so that at least one sprout remains on all segments. Places of cuts are sprinkled with coal. The prepared material is planted in separate pots..

Basal tubers are recognized as the best material. They are carefully removed during plant transplantation, placed in a narrow but deep container (it is convenient to use a plastic cup through the walls of which you can observe the development of the rhizome) with a drainage hole. Rooting occurs in 2.5-3 months, then full-fledged leaves will appear, the bush can be transplanted into a deep container.
