Tree roots lift and break the sidewalk.
Growing roots have incredible power and can easily crack concrete. This is guaranteed to happen if the space between your sidewalk and curb in less than 6 feet and you plant shade trees that grow big and have roots near the surface. Examples – Southern magnolia, oaks, maples, bald cypress, sycamore, sweet gum, and tulip poplar. Plant smaller, ornamental trees instead – crepe myrtle, redbud, dogwood, flowering cherry, crabapple, and orchid tree.
