Healthy alokaziya at home has a well-groomed appearance, its foliage is well developed, there is no trace of sheets and petioles in the home without a trace, well-groomed appearance, its foliage is well developed, there is no trace of sheets and petioles in the home without a trace, well-groomed appearance, its foliage is well developed;yellow, brown or black.
Plants adapted to life in a tropical or subtropical climate and when grown as a room culture require the creation of similar conditions.
The native land of plants belonging to the vast Alokazy genus is the tropical rainforests of southeast Asia, the island states of the Pacific region and northeast Australia.
Here the plants develop:
- with small fluctuations in average daily and seasonal temperatures;
- at high humidity;
- in partial shade, hidden by a tropical forest canopy;
- without experiencing a lack of power and moisture.
It is not surprising that in such practically “heavenly” conditions, the Alokazians actively grow, giving new bright, lush foliage, multiply and bloom.
Requirements for alokaziya home care
But to create a semblance of the natural atmosphere and maintain quality care at home for alokazii not very simple. In summer, in spring and autumn, plants need a temperature in the range of 21 to 26 ° C.In winter, when alokaziya enters a period of relative rest, a slight cooling of the air is acceptable, but not lower than 15–17 ° C.
Most often flower growers make mistakes:
- over-or under-watering plants;
- exposing pots with alokazii on the direct, burning rays of the sun or unnecessarily pushing plants into the shade;
- not taking into account the requirements of the plant to the composition and structure of the soil;
- supercooling pets;
- allowing drafts in the room where alokaziya is contained at home.
It is not easy to maintain in the apartment and the humidity of the air required by the inhabitants of the tropics within 60–85%.
In response to irregularities in the care, Alokazia becomes ill, resulting in a change in the color and tone of the foliage. Sometimes this is limited to spots of yellow or almost black, necrosis of the tips of the leaves, but in some cases alokazii lose foliage and even die. How to deal with the spots appearing on the leaves of alokaziya? And what are the reasons for these unpleasant symptoms?
The main requirements of alokaziya are the sufficiency of light and water. This is where the most frequent mistakes and miscalculations lie.
Alokaziya leaves dry due to illiterate watering
Summer watering, when the flower of alokaziya grows quickly and can bloom, should be abundant and frequent. Plants several times a day irrigate with warm distilled water, while ensuring that the sun's rays do not fall on the wet leaves. If this happens, the drops act as lenses, resulting in burns on the leaf plate and the appearance of yellow spots on the leaves of alokaziya. The fabric under the damaged surface gradually dries out, and with a large area of damage and the entire leaf may die.
For alokazii, not only the quantity but also the quality of moisture is important. If the plant receives cold tap water that is not previously defended, it will certainly respond by rotting the root system, changing the color of the foliage and its wilting.
With the formation of yellow spots on the leaves of alokaziya, flower growers also face situations when the plant suffers from water deficiency or, on the contrary, suffers from its excess. True, in the latter case, the drying leaves of alokaziya is a consequence of the rot that appeared on the roots, which prevents the feeding of the aerial parts and destroys the fabric.
Watering alokaziya at home should, when the top layer of soil begins to dry, and in the depth of the soil still retains moisture. When watering the plant, it is important to completely soak the entire volume of the pot, but be sure to remove excess water from the pan. On summer days, watering becomes more frequent, but when the air temperature drops, you should immediately reduce the frequency and volume of watering.
If this is not done, do not avoid not only the formation of spots on the leaves of alokaziya, disfiguring the plant and weakening it, but also the development of fungal and bacterial diseases. In addition, weak specimens are often affected by insects.
Stains on the leaves of alokaziya due to improper lighting
Ideal lighting for home-grown alokazii is bright but diffused light, without touching the foliage of direct sunlight. The sun falling on the plants, leads to wilting of foliage and yellowish-brown burns on it.
The lack of light is expressed by the extention of the petioles, the shredding of the leaf plates and their pallor.
Composition of the soil and the need for transplanting alokaziya
The unpleasant consequences of planting alokaziya in dense moisture-rich soil, where the roots suffer from stagnant water, and lack of oxygen. This necessarily affects the state of the leaf plates and the whole plant. Experienced growers are advised to add sphagnum moss, chopped boiled bark from coniferous trees, peat, coconut fiber and perlite to aerate the soil.
In order to reduce the risk of diseases that are possible when taking care of alocosis at home, the soil mixture is pre-disinfected, and a tropical crop is planted a day later.
With good care, alokaziya is growing rapidly, so young specimens are transplanted every spring, and adults a little less.
The easiest way is to load an earthen room into a new larger pot, and fill up empty spaces with a fresh substrate.
Without a transplant, the leaves growing in a close pot of alokaziya dry. And in some cases, the plant is able to lose all foliage. The same effect is produced by the lack of supplements, which are necessary in spring and summer. With the active formation of foliage, the plants are fed with complex compositions for ornamental deciduous crops, slightly lowering the recommended concentration. In winter, fertilizers are not needed.
Disruption of temperature and low humidity of air
Reducing the temperature or drafts in the room where the plant is located, leads to the fact that the leaves of alokaziya blacken and dry. Temperatures below 12–13 ° C are detrimental to the inhabitants of tropical forests, and even short-term stay in such conditions kills healthy foliage just yesterday.
What to do if all the leaves have dried on alokazii? Is it possible to bring the green pet back to life, and how can it be made to form foliage again?
If alokaziya is in dry air for a long time or its pot is located close to heating devices, it can be observed that the leaves turn yellow first and then, starting from the tips and edges of the sheet plate, dry.
If you do not take urgent measures, alokaziya discards foliage, and increased watering will only aggravate the situation and lead to decay of the root system and tuber.
What to do when alokaziya dropped all leaves?
First, in this case, do not rush to part with the plant. Often, by getting rid of the foliage, alokaziya reacts to flowering, which requires serious costs and effort from the plant. If alokaziya has faded, the peduncle is removed from it, cleaned of the remnants of dry foliage and arrange the wintering of the plant. With rare watering in a cool, bright room, the tuber will rest and by the spring will begin to form new leafy plates. At this time, it needs to be transplanted into a fresh substrate and feed.
But what if all the leaves on alokaziya dried out after over-wetting the soil or as a result of another florist's mistake? In this case, as an urgent measure, check the status of the root system.
The corm in a healthy plant is dense, resilient, without mechanical damage and no signs of bacterial or other damage.
If there is rot or pests on the rhizome, the damaged areas are cut, and the cuts are treated with coal chips. When the root dries, alokaziya planted in a moist sterile soil. Then the pot with alokazii covered with a film and left in the penumbra at a temperature of 22-24 ° C.
Alokazia diseases and their treatment
Root rot is considered the most common disease of alokaziya in the home. The onset of the disease can provoke both excessive watering against the background of a previous long dryness of the soil, and the presence of the plant in an unnecessarily cold room, on a window sill or in a draft.
As in the situation when all the leaves dry in Alokazia, one cannot do without a thorough examination of the roots and the removal of all the affected tissues. At the same time pruned and damaged leaves. And healthy parts are treated with fungicide and transplanted into high-quality sterile soil.
If the rot is accompanied by softening of the tissues of the stem and stalks, and the pathological process becomes rampant, it is better to part with the plant.
However, in this case, it is necessary to check the soil for the presence of daughter nodules, by planting which, it is easy to get young healthy alokazii favorite variety.
Treatment of diseases of alokazii should be carried out comprehensively and repeated, if the signs of the disease do not disappear. In addition to the use of fungicides, they necessarily set up the care and provide the plant with all the conditions necessary for development.
Pests on alokaziya at home
An important measure to prevent diseases of alokaziya at home is care based on the needs of the plant, and also taking into account the need to protect it from insects.
The most dangerous of them are thrips, aphids, scale insects, mealybugs, nematodes and spider mites that feed on sap. In order to detect insects, they inspect not only the front side of the foliage, but also its rear part, petioles, stems and sinuses.
- It is under dried scales at the base of the stem and in the leaf axils that mealybugs like to hide.
- Aphids are often detected on the petioles and at the base of the leaf plate.
- Thrips are dangerous because they can live on plants and in the soil at different phases of development.
- Nematodes are also found in the soil.
- Spider mites are recognized by a thin web on the green alokazii.
The result of the vital activity of all these pests is the appearance of grayish-yellow or brown spots on the leaves of alokaziya. Growing up, such damage leads to the death of foliage, and possibly the entire home plant.
Treatment for pests consists in irrigating the aerial part of the plant with infusion of marigolds or with prepared insecticides. The foliage can be washed with a solution of green soap and wood ash.
When carrying out such work, it is better to cover the soil with foil to protect it from waterlogging.
If alokaziya is infected with a soil nematode, which can be easily determined by the characteristic nodules on the rhizomes, the plant will have to be destroyed. After all, this quarantine pest is extremely difficult to destroy, and its cysts are also found in the tissues of alokazii.
