Why do banyan leaves turn yellow and fall off?

1. Excessive watering

Cause: Excessive watering causes poor breathing of the roots, which in turn causes root rot. When the roots are rotten, the leaves will naturally turn yellow and fall off.

Solution: If you water too much, drain the water in time. At the same time, control the amount of watering in the future, water only when the soil is dry, and water thoroughly at one time.

2. Fertilization is not suitable

Reason: Excessive or no fertilization may cause yellowing and falling of leaves, so the amount of fertilizer should be controlled reasonably.

Solution: If too little fertilizer is applied, top dressing can be applied, which can gradually improve the yellowing of leaves. It will be troublesome if you apply too much fertilizer. First, you need to take the banyan tree out of the pot and check whether the roots are burned. If so, treat the roots. Secondly, you need to replace the potting soil, reduce the amount of fertilizer, and do not water when fertilizing.

3. Plant root rot

Cause: There are many reasons for root rot. In addition to excessive watering and excessive fertilization mentioned above, it may also be caused by diseases and insect pests.

Solution: When root rot is discovered, the first thing to do is to move the plant out of the pot and cut off the rotten roots. Then check for signs of pests and diseases and repot with sterilized potting soil if none are present. If there is any, prescribe appropriate medicine according to the disease condition and pest type. Appropriate pesticides can be used for pest control. In addition, rotten roots and diseased leaves should be burned in time.

4. The temperature difference is too large

Reason: The large temperature difference between day and night is the main reason for banyan tree leaf drop and even death. Generally, the temperature difference should not be greater than 10℃.

Solution: Generally, the temperature difference between day and night is large in summer. At this time, the banyan tree should be placed in a ventilated and cool place to avoid exposure to the sun. At the same time, water the leaves and the ground, which can effectively reduce the temperature. At night, you should keep warm and move it indoors.
