Question
young tree lots of fruit,leafs are falling off the tree,they are not turning color or curling,this is the first year for fruit,tree is in northeast pa. thanks for any help

Answer
Robert:
Any sudden or drastic drops in nightime temperatures that may have preceded the leaf drop? This can sometimes cause a temporary defoliation, especially if the leaves look good otherwise. Use you fingernail and scratch a few smaller twigs to check for green beneath.  If present, I suspect some sudden, but probably temporary change in environment that may cause this to happen.

Steve
