I have a harvest golden crabapple tree and it's only 2 years old. It has been healthy. But, this year my tree only bloomed the flowers and not the leaves. The leaves are very tiny and didn't fully grow out. Now my tree has dried up leaves. Is it because of the high temperatures and drought? Will my tree survive or is it dying. I have watered the tree deep to give it more water. I put fertilizer in early June, but no luck. Please help.
