III. Excessive fertilization

Hosta has little demand for fertilizer, in addition to the application of sufficient base fertilizer before planting, the plant can be properly applied some potassium dihydrogen phosphate, so that the flowers will bloom very well. Such as excessive fertilization in the growth process, especially the application of thick fertilizer or raw fertilizer, it is more likely to cause leaves yellowing and shedding.
