1、 Maintenance

1. Watering: the root system of Rhododendron is very weak, so be careful not to water too much and keep the soil moist. If you don't water it dry, you must water it thoroughly. If there is no water in the soil, it will grow poorly and it will be difficult to bloom continuously

2. Nutrient: scientific fertilization should be carried out during its growth. Nitrogen fertilizer is usually applied during its growth period, and phosphorus and potassium fertilizer should be replaced at the time of flowering. After flowering, apply more fertilizer appropriately, and don't apply fertilizer in winter for the time being. However, care should be taken not to use concentrated fertilizer or fertilizer that has not been decomposed

3. Pruning: weak and unopened buds need to be cut off during flower opening. After flowering, we have to cut off residual branches, withered flowers and some useless branches. Only reasonable pruning can better blossom

2、 How to alleviate dry leaves

1. Water replenishment: Rhododendron is suitable for growing in a humid environment. If the maintenance environment is too dry, its leaves will not absorb water and will dry up easily. We should replenish more water for it. First, we should keep the soil moist, and then we should spray water to improve the humidity of the maintenance environment

2. Medication: when the plant is infected with diseases and pests, the leaves will turn yellow at first and dry slowly. It should be used at the first time and can be sprayed with carbendazim or dimethoate emulsion
