What to do if Dendrobium leaves fall off

1. Reduce temperature difference

1. Reason: The temperature difference between morning and evening is too great, which will affect the growth of the plant, so leaves will fall off.

2. Solution: Artificially help the plants solve the temperature difference. If you grow it indoors, you can place the plant in a corner and take it out during the day; if you grow it outdoors, you can help the plant to prevent frost at night, so that you can solve the problem of large temperature differences.

2. Watering in moderation

1. Reason: It has relatively high requirements for water. If you water it too much, the root system of the plant will easily have problems. If you add too little water, the plant will dry up. Both of the above situations will cause the plant to lose leaves.

2. Solution: Watering should be done according to different situations. Different situations should be treated differently. It should not be too much or too little. If there is too little water, then water more. If there is too much water, the plant needs to be repotted. Just change to a pot with holes, and the excess water will flow out through the holes without causing any damage to the growth of the plant.

3. Change the soil

1. Reason: There are two possible reasons why the plant may lose leaves. The first is that the nutrients in the old soil cannot meet the needs of the plant. The second is that the soil’s air permeability is poor, which will affect the plant’s absorption of nutrients.

2. Solution: If this happens, you can consider changing the soil for the plant. Or you can mix a certain amount of clay and sand in a certain proportion. This can also solve the problem of plants losing leaves due to soil problems.
