I recently planted a 3 gallon sized Mirte Japanese Maple in my yard. It was planted approximately 1 month ago. (2nd week of September here in Boise Idaho) It had a lot of scorched leaves when I purchased it from a nearby nursery and it proceeded to drop most of its leaves. It has now leafed out again and also has several bunches of blossoms as well. I am concerned that it might be really damaged with the coming frost. Average date of first frost is 10-11 to 10-20 here. I have included some photos. Is there anything I should do to protect it, or is that possible?
