Zantedesia - a beautiful but demanding room calla


The majestic inflorescences of calla-zantedescia have long become classics. Large leaves, reminiscent of silk shields, emphasize their beauty. Blooming zantedesci appear to be luxurious, lively potted bouquets. But their dense and bright bedspreads around the cobs of inflorescences are easily misleading. After all, such a "strong" zantedesk only seems. Being one of the most capricious indoor plants, Zantedeskia does not like any deviations from the ideal environment. And it presents many requirements even to the simplest watering.

Plant description

Heat-loving and hygrophilous, Zantedesia is not an ordinary representative of the Aroids. This is one of the most famous indoor flowering tuberous species. Until now, the name Zantedesky causes a lot of confusion. The plant used to be so often transferred from genus to genus that the former names - calla lilies, callas and even aronica - are still popular.

Indoor zantedescias reach a height of 40 to 80 cm. The basal leaves are very beautiful. Large, up to 45 cm in length with half the width, surprisingly numerous for a tuber plant, ideal heart-shaped or arrow-shaped, with large waves and solid edges. Leaves bloom on elegant petioles up to 40 cm long. The color of greens is always saturated, intense, it seems very bright. During the dormant period, the leaves of zantedesia lose.

Blooming Zantedesky has become symbolic for good reason. Strong, up to 80 cm tall, straight, thick, usually green peduncles end with a yellow cob of inflorescence. Around him, as if wrapping a funnel, a covering sheet-bedspread is an elegant heart-shaped "sail" with an absolutely impeccable shape and a drawn-twisted tip.

Zantedeski is almost always characterized by a very long flowering, although the timing always varies depending on conditions and care. In an ideal environment, zantedeskia can bloom from January to May.

Plants are poisonous, they should be grown with caution in a house where there are small children and pets. But only contact of the juice with the mucous membranes and its ingestion is dangerous.

Types and varieties of indoor zantedesky

Zantedesia Ethiopian (Zantedeschia aethiopica) - the most famous type of Zantedes. A beautiful plant without massive tubers, with wavy-heart-shaped leaves and large snow-white bedspreads.

Zantedesia Elliott (Zantedeschia elliottiana) is a view with narrower, wider open bedspreads and only yellow colors.

Zantedesia Remanni (Zantedeschia rehmannii) is one of the most "colorful" Zantedes species, a compact plant with wavy narrowed bedspreads curled down almost into a tube. Inflorescences are painted in a pink-purple palette.

In many varieties, the leaves also have an original color, on which small strokes and specks of white or yellow often sparkle. For example, elegant touches characteristic of a hybrid variety Green goddess.

Growing Conditions for Zantedes

Warm and light-loving, indoor callas require a special approach to wintering. They can be dug for a period of rest and stored outside the soil. And you can leave it in pots, providing a dry rest period with a simple correction of care. But the conditions are better to choose carefully.

Lighting and placement

For zantedesky outside the flowering period, any fairly bright place is suitable. She feels good in sunny areas, in diffuse lighting and even partial shade, but she cannot stand strong shading.

During the growth of peduncles, the formation of buds and the opening of flowers, calla lilies require good, bright lighting without direct sunlight. This plant prefers 12-hour daylight. In autumn, winter, and cloudy weather in spring, the Zantedeskians are better off installing backlighting.

Important! Direct sun for the Zantedes is "contraindicated" even in winter.

Temperature and ventilation

Zantedeskia for the rest period (usually from October to the end of December) is transferred to rooms with a temperature of about 10-12 degrees, completely stopping watering. But many modern hybrid varieties are able to "rest" at a temperature of about 16 degrees. After transplanting, it is better to keep the plants in intermediate conditions, with a temperature of about 15-16 degrees, after the start of growth, returning them to room heat.

In spring and summer, callas will prefer non-hot places, a stable temperature of 20 to 22 degrees. Zantedesia Eliot requires a cold dormant period of 2 months, which is better to organize in the summer without violating the natural cycle of plants.

Zantedesky should be protected from any temperature changes and sudden changes, lowering the temperature gradually. The plant does not tolerate drafts.

Room Call Care

It is no coincidence that Zantedeskis are considered difficult to grow plants. They are very demanding on humidity, top dressing during the period of active growth and need constant attention.

Watering and humidity

The fall or excess of the usual substrate moisture for Zantedes is unacceptable. The soil should be constantly moist with drying only the top of the substrate. In the period after flowering, watering is reduced to a minimum moisture content (1 watering in 7-10 days). At rest, watering is stopped completely.

To switch to the active stage of growth, indoor callas are first watered with a minimum amount of water approximately 1 time per week. They focus on the beginning of the growth of new leaves and shoots, as a signal to increase watering to abundant.

It is necessary to water zantedeski gently, without soaking the tuber. For the plant, you can use the lower watering and all methods of autowatering. It is watered with zandesdesky warm soft water.

Zantedeski bloom more beautifully, the higher the humidity. For them, it is better to install humidifiers (devices or containers with water and pebbles), in summer the leaves of the plant can be regularly sprayed with warm water.

Fertilizing and fertilizer composition

Fertilizers for the plant are applied only in liquid form. In the dormant period, zantedesci are not fed. During the period of growth and flowering, they need enhanced dressing, which allows huge leaves and inflorescences to develop normally.

For Zantedesky, weekly top dressing with a twice lower concentration of fertilizers or standard procedures once every 2 weeks is preferable. Fertilizers for Aroid or flowering plants are suitable for them. But it is possible to introduce complex fertilizers at the beginning of growth, and potash-phosphorus fertilizers from the moment of development of peduncles.

Pruning and shaping

Dry, damaged, and during the period of active growth and flowering, yellowing leaves in callas need to be carefully trimmed.

Indoor callas are often pruned offspring for more abundant flowering of the main plant.

Transplant, containers and substrate

Zantedesky transplantation can be carried out both after flowering and after the end of the dormant period. Callas are grown in a slightly acidic, peat-containing, nutrient substrate. Special substrates for Aroid or peat-compost earth mixtures are preferred.

It is important for the Zantedean to choose stable containers, because when growing large leaves and shoots often outweigh the container. If the varieties are high, you can additionally install a support for inflorescences.

Zantedeski are transplanted neatly, taking out from the substrate, inspecting and cleaning old and dried roots. At the bottom of the tanks lay a high layer of drainage. When planting, the Zantedean is important to ensure that the growth points remain on the surface and the tubers are not too deeply buried.

Diseases, pests and growing problems

Zantedeskis almost do not suffer from indoor pests (with the exception of spider mites in dry air), but are extremely susceptible to rot. Damp soil, lack of drainage, sloppy watering, during which water falls on the tuber or leaves, are the main risk factors. The fight should include pruning, transplanting, and fungicide treatment.

Zantedean breeding

It is easy to get new healthy callas with the help of daughter plants, which an adult plant forms quite actively. Children are separated during transplantation, carefully planted in small, shallow containers with good drainage according to the same rules as the mother plant.

If zantedeskia does not let out children, the tuber is cut into pieces with several points of growth. Calla is rarely propagated by seed. This makes sense only for industrial purposes.
