centipede dead spots
Well I hope somebody can help. I think I've tried everything.
I live in south Alabama. Soil is deep and sandy. Centipede grass dies in large patches, especially during winter months, and doesn't come back in that spot for 2-3 years. Not even weeds. Does the same with heavy fertilizer, light fertilizer, no fertilizer. I've tried sulfur, lime, and VERY expensive fungicides, as well as mole cricket stuff, at different times in different parts of the yard, same results. I've tried plugging with St. Augustine, and with Zoysia (I just want something green, dont care what). The plugs do OK if in unaffected areas but start declining immediately in the dead zones. Could it be nematodes and if so what can I do? Any ideas please? It doesn't get cold here so its not cold injury. Thanks
