    after watching the ‘color’ video, i am wondering if i have over watered my red maple. i got this summer. i put it in a pot to get a root ball before i planted in the yard. i grew in height and was green all summer. now it is getting brown on the edge of the leaves. any suggestions? also, when would be the best time to transfer it into the ground?
