My Japanese 6 year old maple has been struggling the past few years, but I've been able to keep it looking relatively healthy. This year, I seem to be loosing the battle. The leaves appear burned on the edges and are shriveling up and dying branch by branch. I am doing my best to keep it watered. I don't think I'm over watering. What can I do to save the tree? Should I cut off the branches with the dead leaves?
Coincidentally, there is a 15 year old maple tree about 10 feet away from my japanese maple. It has been healthy until this year. Now, its leaves are drying up and falling off, bit by bit. What can I do to save that tree, too?
