When maintaining, don't let the basin soil be too dry and short of water, especially in summer, the peak season of plant growth, and the high temperature and rapid evaporation of water, so water it a little more frequently. Excessive drought and water shortage will affect the growth of new branches and leaves In the case of sufficient water and fertilizer, the branches of Japanese rosewood grow very fast, and a large number of new branches and leaves can grow in one summer. However, if the branches grow too much and too messy, it will affect the beautiful appearance of the plant and consume a lot of nutrients, so they should be trimmed and reshaped regularly. Pruning one-horned wood mainly includes pruning twigs, dead branches and branches that grow too densely.
