Q.Is tree ok
I have too many questions ? Uhhhh so my lemon tree is looking ok but it seems that something has been eating the leaves. Also I’m planning to report, what should I do and what soil should I use? Any branches i cut off?
From the photo there appears to be some minor pest activity but nothing extreme to worry too much about. I recommend that you adopt a preventive spray program with neem oil every two weeks. That will help to prevent pests and superficial disease like powdery mildew.
As for pruning, the top down view in this photo does not allow me to assess and recommend any branch pruning.
In future please confirm you location in the world, it helps us to give better information. I don't know what Apex means. Or is this a tech term?
