  • urban trees on college campus

    Fall and winter are the best times to plant new trees and shrubs in Georgia.  One of the most important considerations is finding trees that are suitable for a site based on available space.  Decisions to purchase trees on impulse often end with trees that grow too large next to a home or road access…
