I live in north central Delaware and planted an approx. 4' Japanese Maple in October of 2010. It did great through spring of 2011, then we had an unseasonably hot, dry summer after that. Since that time, even though I tried to keep it watered during the summer (maybe too much?), it has looked sickly and the leaves are only at the bottom of the tree. Any ideas on what can be done to help in addition to cutting off the dead growth? Thanks for any advice.
