It is green and alive inside its branches. This will be the 2nd summer I had the tree, never had fruit but I'm afraid that it's sick. My dwarf peach tree has leaves on it now for months and my 7 ft. tall tree is naked. I found a bed of fire ants near it after winter so I didn't want to use poison. I did use liquid to kill the ants but this was when I already knew the tree was not blooming leaves. I hope I didn't cause more damage. When I watered the tree later I saw that the mound of ants had gone close to the trunk of the tree when I was washing away the ants, it was far deeper than I had thought. I live in Houston, Texas. Help me save my tree from the ants or whatever is wrong with it! Oh last year it was beautiful - no bad leaves as I read very health, all my other fruit tree are well! Lemon, orange, plum, mango, avocado, etc.
Or is it something that I did? Please help.
