Sickly mountain apple tree
I have a mountain apple tree in my yard that was looking very sickly. It looked like something was eating the leaves (lots of holes) and the leaves were brown and curly around the edges. We moved in to this house mid-summer and the tree never bore any fruit (I think mountain apple trees bear fruit in the late summer, but I could be wrong).
About a week ago, however, I noticed the mountain apple tree dropping lots of leaves and new, healthy looking leaves popping out. Now the tree looks pretty good! Is this shedding normal for a mountain apple tree?
Also, any tips on getting the tree to bear fruit? Do I need to fertilize or water? We live in lower Manoa and get a decent amount of rain but maybe not enough.
