When potting Begonia, we can choose the culture soil which is made up of four parts of garden soil, one part of river sand, four parts of rotten leaf soil and one part of organic fertilizer. The flowerpot can choose the simple and unsophisticated ones to create the beautiful bonsai of crabapple.
Begonia verticillata is suitable for growing in a warm and sunny environment. The suitable temperature for growth is between 15 ℃ and 28 ℃. In winter, it can endure the low temperature of - 5 ℃, so it is not necessary to put crabapple in the room for heat preservation, but to bury the flower pot in the soil. In summer, when the temperature is high and the sun is strong, it is necessary to properly shade the sun and cool down by spraying water.
Begonia should have enough water in the growing season, but not water in the basin. Spring bogey and summer can be watered more, summer can also be watered every morning and evening in the high temperature. In rainy season, we should pay attention to no ponding in the basin, timely drainage to prevent rotten roots, and reduce watering in autumn. In the growing season, Begonia should apply a thin fertilizer and water once a month. Before flowering, some phosphate fertilizer should be applied to promote flowering. After falling leaves in autumn, fertilization should be stopped.
Pruning the branches of Begonia verticillata can promote branching, control plant type and make it bloom more. Pruning is better after flowering or during dormancy.
Crabapple can turn basin, change basin in early spring or late autumn, and repair roots and branches, and apply some basic fertilizer on basin.
The common pests of Begonia verticillata are cercosus, apple aphid, longicorn and spider. The main diseases are rust.
