Q.lemon tree
I have taken notice of the mealybug infestation and now sprayed it with neem oil extract. However, after I do, there seems to be some yellowish spots on the leaves after it dries. I tried spraying it off with water but it comes back. any help? also if it helps recently theres been a “pollen storm”
Spraying during the heat or sun can cause some spots on the leaves, but without any image to go by I can't determine if this is the cause.
Some diseases could also cause yellow spots on leaves.
