Corinocarpus - care and cultivation
Temperature: this plant prefers moderate temperatures - during the period of active growth (in spring and summer) about 20-24 ° С during the day and 16-18 ° С, in winter when lighting is reduced, it is advisable to rearrange it in a cool room, at 14-15 ° С (permissible minimum + 8 ° С) or set additional lighting.
Lighting: Carinocarpus is photophilous, prefers bright diffused light, but protection from direct sunlight is needed from March to August. The best place in the immediate vicinity of the southwest, southeast window is behind a tulle curtain. In winter, you need a lot of light, the shading will have to be removed before March.
Watering: moderate from spring to autumn, after good drying of the top layer of the earth, in the heat, abundant watering, provided that the soil is very porous. In winter it is strictly temperate, especially when kept cool, watering is necessary only when you are sure that the ground is completely dry. During the growing season in spring - summer, fertilizing watering is carried out once every two weeks, using liquid fertilizer for indoor plants.
Air humidity: Corinocarpus requires very high air humidity, this should be taken into account if the room has central heating. Spray it twice a day - morning and evening. Better yet, place the pot of corinocarpus on a tray of water. If the air is too dry, the plant may shed its leaves.
Transfer: soil - 3 parts of turf, 2 parts of peat land, 1 part of fine gravel, 1 part of coconut substrate. Transplanting young plants annually, adults in 2-3 years. Do not forget about the drainage at the bottom of the pot (about 2 cm high), it can be made from clay shards.
Reproduction: apical cuttings in spring and summer, seeds. Cuttings take root for a rather long time, the best way to root a sprig of corinocarpus (10-12 cm long) is in vermiculite, in a mini-greenhouse, with high air humidity, moderate substrate humidity. Phytohormones can be used for better rooting.
Corinocarpus from seeds reproduces quite easily. Sow seeds in pots in a mixture of compost, garden soil, and sand (or peat mixed with vermiculite). Place in a warm place (22-24 ° C), keep the substrate moderately moist. Germination takes about 1 month. As soon as seedlings emerge, move the pots to bright, diffused light and water regularly to keep the soil slightly damp. When the seedlings grow up, transplant into pots with a diameter of 8 cm.
