Poliscias belongs to the Araliaceae family. The genus consists of 80 species and originates from Southeast Asia, the islands of the Pacific and Indian oceans.
Poliscias is an evergreen tree or shrub, highly branched and with shoots growing vertically. The leaves of different species are lobed, cirrus, simple, of different sizes. They may be uniformly green, and may have marble stains, white spots or fringing.
White flowers are collected in umbrella branched inflorescences, unremarkable.
Types of poliscias
- Poliscias Guilfoyle - branched shrub with large cirrus leaves. Leaf segments in the form of an elongated oval are serrated along the edge and have a white or yellow border.
- Poliscias Shrubbery - a fern-like bush with double and triple-feathered vaginal leaves. Leaf segments can be rounded or lanceolate, with serrated edges.
- Poliscias Fern - is a shrub with leaves similar to ferns 30-50 cm long.
- Poliscias Paniculata - low bushes with cirrus leaves up to 15-20 cm long.
- Policias balfour is an evergreen shrub. It has straight shoots of light green color and round lobed leaves with white bordering and spots. The leaves are located on the petioles and reach 7 cm in diameter. It has several highly decorative varieties.
- Poliscias Tupolistny - This is a shrub with complex leaves, in which the segments are three-lobed and look like oak leaves.
- Poliscias Helmetous - an interesting form of shrub - his central trunk is curved, like a bonsai, the side shoots are thin and straight. Young plants have round leaves, adults - three-lobed with a white edge.
This plant is difficult to care for, in a room culture it grows to 1.5-2.0 m and annually gives an increase of 30-50 cm.
Temperature and lighting
The plant needs bright light with shading from the midday rays of the sun, bushes with monophonic leaves can grow in partial shade. In winter, you need a backlight, since the light mode in winter and summer should be the same.
In summer, the temperature should not exceed 24 degrees, in winter - fall below 18. Warm air from heating devices and cold from window glass can be detrimental to the plant. It is best to place it away from the window on a hill and highlight it with a phytolamp.
The room where polysias is kept needs regular ventilation, but the plant must be protected from drafts. In summer, it can be taken out onto the street or balcony.
Humidity and watering
The soil between waterings should dry on the phalanx of the index finger, in the winter they water a little less. Spray daily and increase humidity in other possible ways. And watering and spraying is carried out with soft, settled water with a temperature slightly higher than the air temperature in the room.
From time to time it is useful to put polyscias under a warm shower - it will not only wash off the dust, but also nourish the bark and leaves with moisture.
Fertilizer and fertilizing
During the growing season 1-2 times a month with fertilizers intended for deciduous plants.
Soil and transplant
The plant is undemanding to the soil, the main thing is that it be light, loose and have a neutral or slightly acid reaction. You can take a ready-made universal substrate or intended for citrus fruits, add perlite, brick chips or sphagnum moss to it. Vermiculite should not be added, since it decomposes after six months under the influence of moisture, and the soil becomes unsuitable for growing plants. You need a pot of ordinary shape with holes and a good drainage layer.
It is necessary to transplant poliscias every few years by the method of transshipment, when the previous pot becomes clearly small for him.
Plant height directly depends on the volume of the pot. The larger the capacity, the higher it will grow. You can’t immediately plant a young plant in a spacious pot - the soil will become acidic and polysacias may die.
Flowering and pruning
At home, the plant does not bloom. With the help of shaping and trimming, you can grow a standard tree or bonsai. In the spring, sanitary pruning is done and weak or “extra” twigs are cut. Throughout the season, pinch the shoots to give the bush a more dense decorative shape.
Poliscias is a plant that is very sensitive to changing living conditions, for example, when turning relative to a light source, it can drop leaves. To grow a beautiful bush that will be less capricious, it is better to root the cuttings yourself or buy a young plant up to 30 cm tall.
To create a bonsai, it is best to use the Poliscias Helmet-shaped - it initially has a fancifully curved thick trunk and will require less labor and time.
You can propagate the plant by air layers or by separation when transplanting root shoots. Other methods are a rather complicated procedure.
Propagation by cuttings
Cuttings with three internodes are cut in the spring, treated with phytohormone and planted in moist peat, perlite or a peat-sand mixture. Contain under glass or a transparent film at a temperature of about 25 degrees and high humidity. Cuttings root badly.
In the spring, seeds of poliscias are sown in a container with light soil, slightly sprinkled with soil. Cover with a transparent film or glass and keep in a dark place at a temperature of 19-25 degrees. When the seedlings appear, the glass is removed, and the seedlings are gradually accustomed to light.
Propagation by pieces of rhizome
The rhizome of the old plant is cut into pieces about 3 cm and vertically inserted into a container of wet sand so that the tip is at the level of the substrate. Landing does not need to be covered.
Pests, diseases and possible difficulties
- Poliscias is affected by thrips, a spider mite and a scab. Treat the plant with an insecticide.
- Leaves fall for the following reasons: dry air, overflow or overdry of soil, drafts, rotation relative to a light source, moving to another place.
- Light spots on the leaves may appear due to excess light.
- Loss of variegation can be caused by insufficient lighting.
- Slow growth causes malnutrition.
