Begonia Rex Care Methods
We usually uses division, leaf cutting and sowing propagation to plant Begonia Rex
. Begonia Rex propagation
by division should be carried out in spring. The rhizome should be divided into two or more segments, so that each segment has at least new buds and 2 ~ 3 leaves. After the wound is slightly dried, plant it into the basin respectively. The depth is better if the upper part of the rhizome is flush with the soil surface or 1 cm below the soil surface. Leaf cutting can be carried out in the whole growing season, preferably in March ~ June or August ~ October in the family. At present, most of the cultivated begonia rex
are excellent varieties, which are clones selected through hybridization. In general, most of the Begonia Rex
seedlings tend to be wild species. Sowing is only used to breed new varieties.
Begonia Rex is produced in warm and humid tropical forests, often in rock crevices and other places where the soil layer is shallow but contains more humus. Special attention should be paid to shading during culture. For cultivation in greenhouse, the shading should be about 70% in summer, 50% in spring and autumn and 30% in winter
. It is necessary to maintain high air humidity in all seasons. We can spray water around Begonia rex
several times a day, and a small amount of water can also be sprayed on the leaves in dry spring. If the air humidity is too low or the sun is too strong, the leaves will roll back, and dead patches will appear on the edge or leaf surface.Begonia Rex potting soil is made of rotten leaf soil or peat soil
, 1 / 3 of river sand and some rotten cow dung and chicken dung as base fertilizer. Potting should not be too deep. It is better to have the rhizome flush with the surface of the basin soil. Begonia rex can change pots every spring to remove the old soil and rotten roots and replant them with new soil.
Begonia Rex is not cold resistant. In winter, the room temperature should be above 12 ℃, and the appropriate temperature is 18 ~ 25 ℃. The high temperature and dry environment is very unfavorable to the growth of Begonia rex, which often makes the leaves small and thick. In serious cases, the edge of the leaves is dry, and the young leaves cannot expand until they die. High temperature and humidity are also easy to cause plant decay. In rainy and high-temperature dog days, we should move Begonia rex to a rain sheltered, ventilated and cool place.
