The leaves of the rich tree are yellow and mottled with white holes, and there are some white water drops on the back of the leaves. What should I do? thank you

This is mainly due to improper environmental protection, in addition, there may be scale insects in the harm! !

You put it in scattered light for the time being, and put it in a sunny place after 10. There is no need to shadow it now.

The soil in the basin must be dried before watering. Wipe the leaves several times with a wet soft rag, and then spray the carbendazim solution1000 times with 800-1 ~ 2 times. Spraying interval is 7- 10 days!

If the ambient temperature can reach 20℃, it is suggested to use thin fat water instead of clear water for irrigation, which is beneficial to recovery!

If the leaves have fallen off too much and the ornamental value is low, pruning can be considered after the temperature rises in the next spring, and each branch can keep 2 ~ 3 hidden buds or the branch is 5 cm long.
