The four seasons of autumn begonia in the growth period every 10-15 days Shi 1 times rotted and fermented 20% soybean cake water, rapeseed cake water, chicken, pigeon dung water or human urine liquid fertilizer can be. Fertilizer, to master the "thin fertilizer" principle. If the fertilizer is too thick or applied to the raw fertilizer is not fully fermented, it will cause fertilizer damage, light leaf scorching, heavy plant death. Fertilizer should be sprayed on the plant with a spray bottle to prevent the fertilizer from sticking to the leaves and causing yellow leaves. Slow-growing summer and winter, less or stop fertilizer, can avoid rotting disease due to stem and leaf tenderness and weakening resistance to heat and cold. Another feature of four-season begonia care is centering. It is the same as jasmine, moon season and other flowers, when the flowers are gone, must be timely pruning residual flowers, centering, in order to promote more branches, more flowers. If you ignore the centering pruning work, the plant is easy to grow long and thin, plant shape is not very beautiful, flowering is also less. After the Qingming Festival, potted plants can be moved to outdoor shade maintenance. East China April-October should be maintained in full shade conditions, but in the morning and evening it is best to see a little sunshine; if you find that the leaves are curled and scorched spots, this is a symptom of sunburn. After the frost, it should be moved indoors to prevent freezing and keep warm, otherwise it will freeze to death if it suffers from frost; the indoor arrangement should be placed in a sunny place. If the room temperature continues to be above 15 ℃, apply fertilizer, it can still continue to bloom. Cultivation and management Light, water, temperature and centering are the keys to planting begonias well. After planting the four seasons of begonia, in early spring can be direct sunlight, with the enhancement of sunshine, must be appropriate shade. At the same time, attention should be paid to the management of water, too much water is prone to rotting roots, rotting buds, rotting branches; high temperature and high humidity are prone to various diseases, such as stem rot Bo? After planting seedlings, every 10 days to apply liquid fertilizer. Timely pruning of long branches, old branches and promote the development of new lateral branches, strengthen pruning is conducive to the beauty of the plant shape. Cultivation of soil conditions, the requirements of humus-rich, well-drained neutral or slightly acidic soil, both afraid of drought, but also afraid of waterlogging. Seed reproduction is the main, cuttings as a supplement. Seeds are small, can be first scattered in the tray, germination and then moved into the hole tray, or with powdered seeds live in the hole tray. Fertility is strong, and it is not easy to survive the high temperatures of summer, but the rest of the year is good. It can be divided into green-leaved and copper-leaved varieties, and the green-leaved varieties are excellent in leaf color under sufficient light. Propagation by cuttings takes place from August to December, and cuttings taken in August can be rooted in about 20 days. Transplant once and set out in about 40 days. Generally apply a thin liquid fertilizer every 10 days and water well to keep the soil moist. If you want to make the clump larger and bloom luxuriantly, you should pick the heart several times, usually leave two nodes, remove the new shoots, to promote branching and bloom more. Potted plants in late June should start shading to avoid the summer heat, and to prevent waterlogging in the pot, otherwise it is easy to rot the roots and die.
