Latin name of the genus was named after the Neapolitan prince von sansevieriya he assisted in the development of natural sciences.In the XVIII century sansevieriya grown in Europe as an ornamental plant.It is unpretentious, quite hardy plant suitable for cultivation in the room conditions.
Lighting. sansevera plants prefer bright diffused light, easy to carry and easy, and full shade.However, we should not forget that bright intense light needed for plant variegation characteristic: in the shadow of the leaves lose their variegated coloring.Variegated types can tolerate a small amount of direct sunlight, but it should be pritenit them from the most intense midday rays.
temperature. Sansevera - plants that grow well on windows east and west directions.On the south side is required pritenenie during the hot summer hours.When grown on the northern windows, leaves become dark green, variegated lose color, but because of the lack of light the plant does not bloom.If there is insufficient l
watering. Sansevera prefers moderate watering from spring to autumn: the soil should dry out between waterings.In winter, watering is necessary to limit and standardize it, depending on the air temperature.When watering in any case, do not expose the liquid in the center of the socket, it will cause rotting leaves.Dangerous excessive watering, and when lack of moisture leaves lose turgor.Humidity does not play a significant role.Sansevieriya normally transports the dry air of apartments.Do not forget to periodically spray it, and wipe the leaves with a damp cloth dust.
feeding. sansevieriya should be fed once a month during the growing season (spring-summer) with the help of mineral fertilizers at half the concentration.For this purpose fertilizer intended for cacti or for indoor crops.Remember that excess nitrogen stimulates root rot, so it is recommended that the ratio of trace elements: N (nitrogen) - 9, P (phosphorus) - 18, K (potassium) - 24. Some growers do not recommend to feed sansevieriya since excess fertilizer can leadto the loss of ornamental leaves.When poor feeding leaves become more stringent.When physical injuries leaf tips may wither sansevieriya.In this case, you need to carefully cut the ends of the leaves are dry, leaving little dry zone in the form of thin strips.Otherwise, the sheet will continue to dry.
transplant. repot the plant sansevera recommended only when the pot close to them would be: every 2 years for the young and every 3 years for adult plants.A sign that the plant needs transplanting, the roots are protruding from the pot.Roots have sansevieriya tend to grow wide, then the pot should choose shallow, but wide.Powerful sansevieriya roots can break close capacity.On the other hand you get abundant flowering only when the roots opletut earthen room.Therefore, the new capacity should not be very large.At the bottom of the pot to do the drainage of fine gravel, broken shards, pieces of charcoal, expanded clay.Sansevieriya undemanding to the composition of the soil.It is recommended to use a mixture of leaf and turf ground with sand in a ratio of 2: 4: 1. It is added to peat or humus soil.A good combination is considered to turf and ground sheet, humus and sand in the ratio 2: 1: 1: 1.Sometimes mixtures of geraniums and 30% coarse sand for good drainage.Sansevera well cultivated hydroponically.
reproduction. multiply these indoor plants vegetatively: side shoots, dividing rhizomes, leaf or division.Variegated forms are preferably propagated by dividing the rhizomes to keep specific characters.
precautions. sansevieriya three-way refers to poisonous plants, it contains saponins, which in case of poisoning causes nausea and vomiting.Make sure that children do not chew leaves.Contact sap on the skin does not cause irritation.
- If the leaves turn yellow and become soft at the bottom, and then die, then there is a soil moisture and watering is carried out incorrectly (in a cool or in the center of the socket).In this case the plant requires immediate transplantation and removal of infected leaves.
- If the roots have the same bend, then take root healthy parts of the plant, for example, part of the leaf.
- If the leaves wither and rot, and there is no waterlogging, the reason for the cold sansevieriya content.Move it to a warm place and remove any damaged leaves.In the case of stem rot, take root healthy parts (top of the page or socket).
- If the leaves appear dark brown spots, then the ground is very wet and the plant is contained in a dark room for him.
- If the leaves appear hollow red-brown spots with yellow rims, then sansevieriya infected with fungus.
Pests: spider mites, thrips.
