The pruning was done many years ago actually, when we first moved in because it was in such poor shape. The same thing with the damage to the trunk, that was about 10 years ago from the previous owners.
Last year this tree looked awesome.
Thinking about it now, someone said that the roots may have a problem. When I lost the lemon tree to the left by two trees, I do recall the roots being in poor shape.
I'm thinking that the fundamental problem may be the drainage of the yard. Whoever laid out the drainage system for the yard (three owners ago) they ran the drain pipes right under these trees! Yeah, thanks a lot. I had a major problem with drainage from the day I moved in. I'm wondering if there a ton of stagnant water in these pipes causing the trees to get diseased.
I don't know what else could be causing it. But I do know we have had a horrible time with Aphids, and other types of bugs. I have been spraying like crazy but no matter what I do they keep coming back.
Poor tree. Last year it was BEAUTIFUL!! That kinda makes me think that there is more then one thing going on here. I'm wondering if the neighbors drainage is as bad as mine, we got new neighbors last year and now maybe something bad is getting into the system?
