There are two possibilities for this situation:
First, excessive nitrogen fertilizer, phosphorus, potassium fertilizer deficiency;
The second is improper pruning, so that there are too many hidden branches and weak branches and the supply of nutrients is poor.
Fusang should generally be pruned and changed indoors at the beginning of March every year. When pruning, leaves 2 to 3 buds on each side and branches, and the rest should be cut off. At the same time cut away the branches that cross and ingrown, as well as weak side branches, and then use a full-fledged fertilization soil with fertilizer to plant.
The method is: First, the original strain is pulled out of the pot to remove the lateral roots near the soil surface, which is what people call a “false head cover†and retains the protection of the soil. Then put a 1 cm thick pelt piece in the basin as a drainage layer, spread a layer of subsoil on it, and put a proper amount of horseshoe pieces as the base fertilizer according to the size of the plant. The base fertilizer is then covered with a layer of soil to make the root system of the plant not Direct contact with horseshoe. Immediately put the soil ball into the plant, fill with real soil, and pour water, and put it in a place where there is sufficient sunshine and temperature. In the future, every 10 days or so, fully pour organic liquid fertilizer (concentration 10%), so that flowers can bloom in June.
