Yikes...problem w/citrus trunk....citrus experts?
I was piddling around my yard today and notice that the bark at the BASE of my pink grapefruit is cracked and chunking off in areas.
I cannot tell you how much I adore this tree.
It's being overly-shaded by a large, laurel oak that was planted by prior owners much too close. I am getting ready to call a tree trimmer to trim it back so it can get more sun.
Due to the excessive shade, the leaves have been dying and some of the bare, leaf-less branches have peeling bark. Fruit production has gone way, way down. I used to get tons of fruit - more than I could eat. Now, I 'maybe' get 2-3 dozen.
It's not being over-watered. This year, I tried the Bayer tree insecticide that GCMastiff recommends. The fruit looks prettier, but I am thinking another dose for next year will help it look better.
What do I need to do to help it? Will this bark-peeling at the trunk kill it? What is the problem? Any ideas?
Help, help, help!
