What to do if the leaves of green apple arrowroot turn yellow

1. Improper lighting

Reason: Apple calathea needs proper sunlight to grow. If it lacks sunlight for a long time, photosynthesis cannot be completed, which will naturally cause the leaves to turn yellow. It also cannot be exposed to strong light, otherwise the leaves will be sunburned, which will also cause yellowing of the leaves.

Solution: If there is a lack of sunlight, you need to place it in a place with good light. If the light is too strong, you should place it in a cool place and wait for recovery.

2. Improper watering

Reason: It is a plant that likes moisture and humidity. If you do not water the flowerpot for a long time, it will be difficult for the roots to absorb water, which will lead to weak growth and yellowing of the leaves. At the same time, if you water too much, the roots will not be able to absorb it all, which will also cause the leaves to turn yellow.

Solution: Water the plants appropriately at normal times, and make adjustments if there is too much or too little water.

3. Improper fertilization

Reason: It likes fertilizer. If it lacks nutrients, the old leaves will turn yellow due to lack of nutrients. However, if too much fertilizer is given, new leaves will have problems and old leaves will fall off directly.

Solution: First determine whether it is fertilizer deficiency or fertilizer damage, and then make adjustments.

4. Prevention and control of pests and diseases

Reason: If there are diseases and pests, they will also affect the leaves.

Solution: Strengthen prevention through regular ventilation and provide appropriate treatment upon discovery.
