What to do if banyan tree leaves turn yellow and fall off

1. Lighting and ventilation

Reason: Insufficient light and poor ventilation in the growing environment will cause the banyan tree to develop poorly and also cause leaf fall.

Solution: Place the banyan bonsai in a place with good air circulation and sufficient light, ensuring that it is exposed to light while not being overexposed to the sun to prevent large temperature differences from causing the banyan tree's leaves to turn yellow and fall off.

2. Increase humidity

Reason: Dry air is also a major reason for banyan tree leaf drop. Banyan trees have high requirements for moisture in the air, and maintaining a certain humidity is beneficial to their growth.

Solution: Use a watering can to spray water around the bonsai. You can also sprinkle water on the ground to increase the humidity of the surrounding environment.

3. Water appropriately

Reason: Banyan trees do not require much water. Overwatering can easily lead to root rot, which can cause the leaves to turn yellow and fall off.

Solution: Control water supply of banyan tree properly. There is no need to water unless the soil is completely dry. At the same time, water thoroughly at one time so that the entire pot is wet from top to bottom. Do not just wet half of it, which will also affect the growth of the banyan tree.

4. Loosen the soil

Cause: Soil compaction prevents water and fertilizer from reaching the roots, and they can only remain on the soil surface, making them unable to be absorbed, resulting in poor development and subsequent leaf fall.

Solution: The soil needs to be loosened regularly and replaced every two years. It is best to add a certain proportion of sand to the soil to increase air permeability and drainage.

5. Spraying pesticides

Reason: Pests and diseases are also important reasons why banyan trees turn yellow and fall off.

Solution: The main pests that affect the health of banyan trees are aphids, red spiders and scale insects, which can be killed by spraying with omethoate mixed with water.
