Q.My Maple Tree Isn’t Leafing Out. June
My maple tree has failed to leaf out this spring. We had a late snow and cold temps here in CO and now the tree has buds but they aren’t developing. There is new growth at ground level around the trunk so I don’t think that the tree is dead. It is about 5 years old.
