any tips to save / rejuvenate my Japanese Maple
Long ago, when I was young and stupid, I hacked my Japanese maple which was quite tall and blocked the front door... I think that hack job might have left it prone to disease... now, the last 3 summers, 1/2 thru the summer, it looks near death. Anything I could do to bring it back? i.e., cut the major left arm off? some kinda disease juice? I know how much these cost and would love to make this old grandma healthy again!
