10 days of 100+ Heat killing my Sangokaku
I am new to Japenese Maples and need help. I put a beatiful coral bark maple in the ground last fall, and it now appears to be suffering from the heat.
Most of the upper leaves have browned and dried, and the bark is turning black from top now into the trunk. This has happended in the 3 days I have been out of town, though my regular watering schedule was on....
