I planted a japanese maple last year and I am having a few problems. The leaves were red all of last year but this year they turned green after a month or so. Now nearing the end of summer some of the leaves are turning black and there seems to be a light greenish mold on the trunk. Could this (the blackening leaves) be due to the intense heat we are having this summer? The tree is planted where it gets sun until about 1 o'clock and then it is shaded the rest of the day.
Is there any way to post pictures on this forum?
I am Extremely new to having any type of garden so any comments will be appreciated.
