1. Poor ventilation

If the ventilation is poor for a long time, it will weaken the growth of Rhododendron and cause diseases and insect pests such as red spider and aphid. If the situation is serious, it will cause plant death. Therefore, we should pay attention to ventilation at ordinary times. We can't put it in a place too closed for a long time

2. Light discomfort

Rhododendron needs to scatter light, and the light can be bright. If it is exposed to direct sunlight for a long time or in a state of too much shade for a long time, it will grow poorly, and the plant will die in serious cases. Therefore, it is necessary to improve the lighting conditions and give it bright scattered light

3. Improper watering

The roots of Rhododendron are relatively thin and dense, so the soil is required to be in a wet state. Too dry or too wet will have an adverse impact on it and cause death in serious cases. Therefore, watering should see dry and wet, and keep the basin soil moist

4. Improper fertilization

Rhododendron blooms more and its root system is thin and weak. It likes fertilizer but is afraid of thick fertilizer. If the amount of fertilizer applied at one time is too large or the fertilizer without decomposition is used, the plant will also die. Therefore, thin fertilizer should be applied frequently, and rotten fertilizer should be used

5. Didn't change the basin

The root system of Rhododendron is developed and weak, and flowering consumes too much nutrients, so it is necessary to change the basin every year, at least once every 2-3 years. If the pot is not changed for a long time, its root system will be longer and denser, which will not only lack oxygen in the soil, but also accumulate harmful substances in the soil, resulting in plant death. So we need to change the basin for it in time
