My grandfathers old coastal bermuda hay meadow has been mostly taken over by bahia grass and in many places the smutgrass is probably 80 percent of what is there. There are also persimmon saplings which are being controlled by Remedy and diesel basal bark treatments. The broad leaf weeds, mostly goat weed and dogfennel, are being controlled with Grazon P plus D. My question is what to do about the smutgrass. I have been spot spraying with glyphosate and water but was wondering about plowing out the smutgrass this coming February. There are two plows available to me, a four bottom moldboard which will run behind a JD 4020 and a chisel plow. If use the moldboard and then disk it smooth, and do not reseed or re-sprig, will the coastal return? Should I continue with the labor intensive back pack spot spraying of glyphosate and water? Should I plow and reseed to something other than coastal? Probably not going to be able to plow and re-sprig the coastal. Any comments appreciated.
