In nature, the kutrovy family consists of more than 5,000 species of various plants. But among kutrovy indoor plants, there are about twenty species. This is an extensive family of dicotyledons in the form of trees, shrubs and shrubs, lianas, perennial grasses and even succulents, common in tropical and subtropical regions around the globe.

The kutrov family includes five subfamilies:

  • Apocynoideae
  • Gully Asclepiadoideae
  • Ornate Periplocoideae
  • Rauwolfian Rauvolfioideae
  • Secamont Secamonoideae

Distinctive features can be characterized as follows: Kutrovye have, as a rule, leaves of a simple form, oppositely located on the stems. Plants contain milky sap and poisonous alkaloids. Therefore, the ingestion of juice from the stems, leaves and flowers of plants in the mouth can cause not only a burn of the mucous membrane, but also poisoning.

Flowers are single or collected in inflorescences, bisexual. The bend of the rim is five-membered, turning into a narrow tube. Most kutrovy propagates by stem cuttings in spring and seeds.

By the way, the Grimaceae are now assigned to the Kutrov family as a subfamily - these are the well-known hoyi, stephanotis, stocks, etc.

Care for kutrovye

  • Keeping in the summer at normal room temperature, in winter in the cool about 12-14 ° C.
  • A place for kutrovy is chosen, as a rule, in bright diffused light with some direct sunlight in the morning or evening. For some kutrovye shading is not required at all. But after a cloudy winter, any plants are gradually taught to the spring sun. In the summer, after the threat of strong nighttime cold snaps has passed, the plants can be taken out into the garden.
  • Watering is required plentiful in summer, much more moderate in winter, depending on the temperature in the room, avoiding only overdrying the earthy coma. Most kutrovye do not tolerate waterlogging, their roots rot easily.
  • During the period of growth and flowering, shrubs must be fertilized. For this, complex mineral fertilizers are used for decorative flowering or decorative deciduous plants. For some large tree-like plants, such as oleander, you can alternate fertilizing with mineral and organic fertilizers. At the same time, succulent plants, like the pachypodium, are fed only with mineral fertilizers and no more than 1 time per month.
  • Young plants are transplanted annually, old ones after 2 - 3 years. A soil mixture of 3-4 parts of turf and 2 parts of leafy land, 2 parts of humus or greenhouse soil with the addition of 1 part of sand. It is better to drain in a pot or tub. During transplanting, you can carry out partial root pruning of large tub plants.
