The name of the genus arose as a result of the fusion of two Greek words "polys" - which means a lot and "skias" - in translation the shadow. This name is ambiguous. The first value indicates the presence of a dense crown, which gives a large number of shadows. The second is that the poliscia grows in a damp shady area. Both interpretations reflect the characteristics of the plant. Poliscias is an evergreen tree or shrub that has smooth branches with lobate, twice or thrice pinnate leaves. The flowers are small, umbrella-shaped or collected in the head, the inflorescence is paniculate.
Polisias fern-leaf is a good material for the manufacture of medicines. With the help of which a person can adapt more easily in adverse environmental conditions, resistance to radiation, infectious diseases, emotional stress increases.
This plant looks good in a beautiful ceramic pot in a single specimen, but large species are too expensive. In general, the poliscian is very fond of. For good growth, it requires normal illumination, the soil moisture should be uniform at the roots, and in winter there should be heat. The main problem with cultivation is the humidity of the air: the polysia does not tolerate dry air.
Kinds.
P. Guilfoyle . Strongly branching shrub up to 3 m in height. With large, unpaired-pinnate leaves. The leaves are oval-lanceolate, edged, green, with a yellow or white border.
P. shrub. The native land of the plant is considered to be East and South-East Asia, Polynesia. Shrub to 2 and a half meters in height. Young shoots have convex lenticules. Leaves are twice, three times pinnate. The base of the petiole can be widened into the vagina. Leaves on petioles, various forms (they are rounded, lanceolate, sharp, at the edge of serrate-dentate). Inflorescences apical. Flowers are white, small, unsightly.
The garden form of multifida is a plant that has a large number of linear or linear-lanceolate segments of leaves ending in light bristles.
P. fern-leafed. Homeland plants consider Oceania. It is an evergreen plant, a shrub up to 2 and a half meters in height. With long, pinnately-dissected, green leaves; with pinnate lobes, densely located segments. There are several varieties of decorative appearance.
P. Tupolevistic. A plant with complex leaves, which have rounded trilobate leaf plates, reminiscent of oak leaves. Plants of this species grow well in any room conditions.
P. helmet-shaped . This decorative form has a very unusual structure. This plant with a very thick, curved, bonsai-like trunk, and thin erect lateral branches. With a large number of leaves, whole, rounded in plants younger, and consisting of 3 leaves of older plants. The leaves are shiny green with a white border. Marginata varieties have small-toothed edges, a wider margin.
Care rules.
Poliscia - indoor flowers, which are very whimsical, they are difficult to grow in culture.
Polisatsu likes shady light, without hitting the sun. The most suitable place for cultivation are the windows of the eastern or western sides. When placed on windows on the south side, the lighting should be diffused. To do this, use transparent fabrics (gauze, tulle) or paper (tracing paper). Cultivation of green leaf forms is performed on windows with a western orientation, and additional illumination is required for growing variegated plant forms. Lighting in winter should also be sufficient.
In spring and summer, the cultivation of the polysia requires t ° approximately 20 ° C, and at t ° above 24 ° C, a high humidity is necessary.
In autumn and winter, t ° should be between 17 and 20 ° C. Heating plants and appliances must be removed away from the plant, because the presence of too dry and warm air can damage the poliscia. The room in which the polysystem grows should be regularly ventilated, avoiding drafts.
Polisias are flowers that require moderate watering. In the winter, you can water it one to two days after the top layer dries. Water for irrigation should be room t °, in winter - two or three ° higher. Inadmissible excessive moistening and drying of the substrate, the land should always remain moistened.
Polisatsu likes the high humidity in the room. It needs to be sprayed throughout the year once or twice a day. Water for spraying must be defended and filtered. The plant is placed in a place where the air is maximally moisturized. In order to increase the humidity, the plant is placed on a pallet in which wet moss, expanded clay or pebbles are placed. Do not let the bottom of the pot touch the water.
Sometimes poliscies washed with a shower. This allows you to save the plant from dust, fill its leaves with additional moisture. During this procedure, the bowl is covered with a packet so as not to wet the ground. Wet greenhouses are an ideal place for a poliscia.
In the period from May to August, once every two weeks, these room flowers should be fed with complex fertilizers. In autumn and winter you can not feed.
Plants younger must be transplanted once a year in the spring, and more adults are transplanted into pots larger once every 2 years. Specialists recommend such earth mixtures: 1) a mixture of sod-humus earth and sand (5: 2, 2: 1: 0): 2) a mixture of equal proportions of peat-sheet-sod-humus and sand. Be sure to use good drainage at the bottom of the pot. Polisias can grow and with the help of the method of growing without soil (this method is called hydroponics).
The plant room polisiasis is multiplied by placing the cuttings in the crates, ct ° of the earth mixture from 25 to 26 ° C. After the cuttings take root, they must be planted in 7 cm bowls. Substrate composition: 2 parts of turf, 1 part humus, 0.5 part sand. Then the plant should be placed in a place with sufficient moisture and with t ° above 20 ° C. A moderate watering is required.
Difficulties that may arise.
- If the room is low in air humidity, then the leaves can burn around the edges and fall off.
- The plant is very sensitive, both to a lack, and to an overabundance of moisture.
- When placing in a room, one should take into account the fact that the polysystem does not like drafts.
- Not enough moisture of the air leads to damage to the scabbard and aphids.
