I planted a Silver Dollar Eucalyptus Tree on 7-5-86 after finding it lying on the side of the road. (Approximately 3' tall.) It is now over 30' high and shades the house during our hot summers. Recently I noticed some branches without leaves and other branches with curled or spotted leaves. Can someone tell me if I have a problem? I'd hate to lose this tree. I'm used to the broken off branches and scattered pieces of bark. About how far outward would the roots extend on a tree of this size? There are no visable roots, and I don't have any cement to crack. Thanks in advance...
