There are several garden forms of this plant, which differ in the size and shape of leaves and flowers.

Caring for Allamandra

Tropical Liana Allamand

This is a very demanding plant: good lighting, regular feeding, annual transplanting and pruning. Here's what you should be prepared for if you decide to grow Allamand.

Both in summer and in winter the plant needs a light or slightly semi-dented place: it is best to place it on the western or eastern window. The shoots of Allamand must be directed along a wire stretched as a support, so that the buds and flowers receive sunlight without restriction. An obligatory procedure is pruning, even in slow-growing forms, more bushy plants are obtained by pruning long shoots. The formation of a large number of flowering shoots contributes to pruning and shortening the vine after the end of growth - approximately in the month of November. It should be remembered that the milky juice, released in slices, is poisonous.

During the period of intensive growth (namely, from April to September), abundant watering and frequent spraying are necessary; in winter, Allamanda is watered sparingly and not sprayed. The dormant period of the plant lasts from November to the end of February. To maintain a good growth rate and long flowering, Allamandu is fed weekly from the beginning of April until the end of August with a solution of full fertilizer, in the winter it is enough to do it once a month. A sign of a lack of nutrients is yellowing of the leaves. It is possible to replant the liana if necessary, it is best to do this before the start of growth - from February to March.

Allamand should be grown in a substrate consisting of leafy soil and peat. It is advisable to add sod land, humus and sand.

The temperature regime should be maintained at 16–20 ° C, in summer - closer to the upper boundary, in winter - to the lower. It is necessary to avoid drafts and bright sun, since both of them create a prerequisite for defeating the plant with mealybugs, aphids, spider mites, and scutes. With improper or poor care (especially if the room is very dry air), Allamand can get a black leg.

Propagating plants is best in March-April: for this purpose, stem cuttings are taken. They are rooted in water or sand, using phytohormones and underheating.

Possible problems and their causes

  1. If the plant is drooping, the cause may be too dry soil, or - in winter - excessive watering at low temperatures.
  2. If the plant has stopped to bloom, the cause is most likely a lack of light and / or nutrients.
  3. If the vine is too stretched out and loses a neat, attractive appearance, firstly, pruning is required, and secondly, the plant may not have enough light.
  4. If the leaves turn brown and curl in winter, the plant is too cold.
  5. If the leaves turn black and the stems begin to rot, it is necessary to treat the plant with a fungicide and transfer it to a warmer place.
