Q.My Lemon tree is losing leaves
The falling leaves look perfectly healthy. I have tried keeping the soil damp and that hasn’t helped. I just purchased this tree about two weeks ago.
I suspect that this is either a watering or nutrient issue (or combination of both). It is my recommendation to review the watering and fertilizing guidelines for citrus trees in the articles below:
