If the ventilation is not good for a long time, the Rhododendron will grow weakly, which will cause diseases and insect pests such as spider and aphid. If the situation is serious, the plant will die. So usually, we should pay attention to ventilation, not put it in a too closed place for a long time
Rhododendron needs to scatter light, and the light is bright. If it is exposed to direct sunlight for a long time or is too shaded for a long time, it will not grow well, and the plant will die in serious cases. So we need to improve the lighting conditions and give it a bright scattering light.
The roots of Rhododendron are relatively thin and dense, so the soil is required to be in a wet state. Over drying or over wetting will cause adverse effects on it, and even death. So water to see dry see wet, keep basin soil moist.
Rhododendron flowers more, the root system is relatively weak, more like fertilizer but afraid of thick fertilizer. If too much fertilizer is applied at one time or the fertilizer without maturity is used, the plant will also die. Therefore, we should apply thin fertilizer frequently, and use mature fertilizer
The root system of Rhododendron is developed and weak, and its flowering consumes too much nutrients, so it needs to change basin every year, at least 2-3 years. If the basin is not changed for a long time, its root system will grow more and more dense, which will cause anoxia in the soil and accumulation of harmful substances in the soil, leading to plant death. So we need to change the basin in time.
