I have a lemon tree and it is losing its leaves. I live in AZ and have grown citrus before. It is still green and has golf ball sized fruit but some leaves are browning and dropping. Is this due to the heat of because I used fertilizer on it for the first time? I do not think it would be from trasnplanting since that was a couple of months ago.
