Last winter all leaves on tree came off, but this spring and now 6/17/05 (2) of my trees still donot have any leaves. I live on a lake and the house is 1 1/2 yrs old. New Construction work stopped a yr ago, and last year these trees all had leaves. I see what looks like buds on these two trees for some time but still no leaves. Are these trees dead? What can I do for this problem?
