Methods to solve the problem of yellowing of dendrobium leaves 1. Appropriate watering: Keep the soil slightly moist and avoid excessive watering. When watering, ensure that the water can penetrate deep into the soil to avoid stagnant water.
2. Increase the light appropriately: Place dendrobium in a place with sufficient scattered light to avoid direct sunlight. If conditions permit, artificial light sources can be appropriately increased.
3. Improve the soil: Choose soil with good air permeability and strong drainage, and regularly replace the soil to maintain the fertility of the soil.
4. Prevention and control of pests and diseases: Regularly inspect dendrobium and treat pests and diseases found in a timely manner. Biopesticides or physical methods can be used for prevention and control.
