What to do if the leaves of the green treasure tree turn yellow

1. Pest problems

(1) Cause: If the plant is kept in a place with very high temperature, high humidity and poor ventilation for a long time, such as if it is kept in a greenhouse for a long time, then insect pests are likely to occur. The pests mainly concentrate on the leaves of the plant, and if this continues for a long time, the leaves will turn yellow.

(2) Prevention and control methods: First, if there are relatively few insects, you can wipe them off with a damp cloth, or use transparent tape to stick them away; if there are many, you will have to spray some pesticides, such as 25% cypermethrin powder. In addition, it is also very important to control the surrounding environment, such as increasing ventilation and letting in as much light as possible.

2. Lighting issues

(1) Reason: We all know that plants rely on light to produce chlorophyll. If the light is weak for a long time, the leaves are likely to turn yellow. Over time, more and more leaves will turn yellow.

(2) Solution: Try to place it in a place where it can receive scattered light, and avoid keeping it in a dark place for a long time; in addition, it also needs to be kept away from strong light.

3. Ventilation problem

(1) Reason: This is also an important reason why the leaves turn yellow. Especially in summer, when the temperature is very high, yellowing of leaves is likely to occur if ventilation is not increased.

(2) Measures: In this case, we must of course strengthen ventilation. Bring fresh air to the plants to make them healthier.

4. Normal phenomenon

(1) Cause: Sometimes, yellowing is a sign of leaf aging, which is normal, so don't worry.

(2) Measures: If this is the case, simply cut off the leaves.
