help!!...i live in the pacific north west and have a number of ornamental
cherry trees...they start out fine in the spring - bloom beautifully,
start to leaf out, and not long after the leaves appear, they start to
deteriorate - they look almost burnt in places, and eventually fall
leaving the tree looking like late autumn instead of high summer....since
one of these trees is growing up thru my deck and provides important shade
in the summer as well as branches for all my bird feeders, i really hope
there is nothing seriously wrong....any suggestions as to what could be
wrong or what i could do?

thanks in advance!
