Hey All: About a year and a half ago I bought a house and huge yard in SC. My neighbor also from TN. moved there about 12 years ago. After watching me and inquiring about what I was doing and telling him that I had some experience in agriculture, he showed me some HUGE MOSS in his yard near some Bradford pear trees but not fully under them. These are huge mounds and turn black when water hits them. On first guess I though LIME DEPRIVED. But, under there he said was an old road bed of cocina (Shells that are used to pave driveways). This stuff is about 6-8 inches down. Soil is really sandy. Got any answers. I ran it by Clemson Extension Agent in Georgetown--Nothing. I'll try to get a camera to put it here as soon as I can. Meantime there is something like short Spanish Moss growing from his Azelias nearby also. Close to his house and don't get much water. Same with a Creap Myrtle in behind. These two mossy things are not in any of my old books and hope that someone would recognize the problem and help me help him out. Thanks to a bunch of nice folks here. Got any ideas?
