What to Do When Dendrobium Drops Its Leaves? Causes and Solutions

1. Reduce the temperature difference

1. Cause: Too great a temperature difference between morning and evening affects the plant's growth, so leaf drop occurs.

2. Solution: Manually help the plant deal with the temperature difference. If it is grown indoors, you can place the plant in a corner and bring it out during the day; if it is grown outdoors, you can protect the plant from freezing at night, and this will solve the problem of a large temperature difference.

2. Water appropriately

1. Cause: It has relatively high requirements for water quantity; too much watering easily causes problems with the plant's root system, and too little water makes the plant dry up. Both of these situations can cause the plant to drop its leaves.

2. Solution: Watering should be done according to the situation, treating different situations differently; it should be neither too much nor too little. If it is too little, water a bit more; if too much water has been given, the plant needs to be repotted. Simply switch to a pot with drainage holes, and the excess water will flow out through the holes without harming the plant's growth.

3. Replace the soil

1. Cause: The plant dropping its leaves may also be due to the following two situations: the first is that the old soil cannot supply enough nutrients for the plant's needs, and the second is that the soil's air permeability is poor, which affects the plant's absorption of nutrients.

2. Solution: If this happens, consider repotting the plant. Alternatively, mix a certain amount of clay with sandy soil in a certain ratio, which can also solve the leaf drop caused by soil problems.
