I've been undertaking a campaign to save my orange tree and have made some progress. I live in Arizona and wasn't adequately watering it before, but have since mulched around the tree and deep water it more thoroughly.
I've also fertilized it and I think I see some improvement (at least haven't seen it worsen), but I have some more questions on things I might be able to do to help.
Pruning the dead branches/twigs that are still on there. In this album you can see there's a few larger branches (first picture: the one starting on right, curves over left, is entirely dead) and some smaller ones (second picture) I planned to remove.
Should I be concerned about the appearance of the bark in the first picture?
Is this a good approach to take? If the tree is in recovery mode, I don't want to do anything to cause it more strain if it's not going to help it.
