brown branches on rio red
I have a rio red grapefruit tree that has been in the ground about two years. This past season I had a lot of grapefruits on the tree. I know the tree suffers from citrus leaf minor which I use a monterey garden with spinosad spray and some volk oil that I heard about on this forum. My question is why are some of the branches losing their leaves and turning brown? I wanted to post some pics I have but I am not sure how to in this message. thanks in advance.
