One year ago my lemon tree was growing and doing ok, until this year. The lemons do not grow enough, instead they fall out. What do I need to do to prevent this from happening? I don't know if there's a certain insect that is preventing my lemon tree from growing? Or do I need to put some sort of vitamins? Please tell me what should I do?
