Sick Tangerine!! help!
We hit it with a heavy done of fungicide two weeks ago and it has continued to get worse. What started as spots and progressed to yellowing leaves and a leaf drop has now led to open sores on this tree. Six months ago I would have told you this was the happiest tree on the block, we got an amazing crop of fruit from it.
Please please tell us what we can do to save this tree. Should I cut off the branch with the open sore? That is the only one like it on the tree, other than that we have spots bigger than a silver dollar on the branches and some leaves yellowing/dropping.
Possible I could have overfertilized it, but that would've been many weeks ago.
