Q: What is the best type of sand to use following aeration of our bermuda lawn to help provide better drainage for the Georgia red clay?
A: I don’t recommend using sand after aeration. Experts say that you need to add LOTS of sand to make any difference in overall soil drainage: perhaps an inch or two spread over the whole lawn and incorporated thoroughly. You’re looking at more than 3 cubic yards of sand per 1000 square feet plus the work to till it eight inches deep. If your soil is hard you can either aerate thoroughly every spring or remove the grass and renovate the whole lawn. Details at bit.ly/sandsoil.
