How did you grass do after your post? We are having what we think are chinch bug problems and DH oput down the Triazide twice. The areas are getting larger and very little grass is coming back in the first areas that died. I would like for us to go organic and start using beneficial nemotodes which over time will help get rid of the chinch bugs. Then use some type of cornmeal that you get at a feed store. Got this info on the Florida Gardening forum. What did you do to help your lawn recover. We are in lakeland.

Yes, I recognize this is an old post, but for the benefit of others landing on this page... I'm 99% sure this is Creeping Beggarweed or Spanish Clover (D. incanum/D. laxiflorum). Mine produce a deep pink, almost purple flower. I spent an exhaustive afternoon in my back yard digging a ~6' x 6' patch of it out of my St. Augustine about 2 yrs. ago. I would compare the underground root system to that of Torpedo grass... invasive and virtually impossible to eradicate. My temporary joy of digging out the mother lode tap root (at least 10" deep!) was quashed when sprigs of it started popping up again. As the natural/organic method failed, I got some Roundup. The grass has almost fully recovered now; I get an occasional sprig though. Then I noticed it was invading a stretch of front yard near the street. Mother Nature sent Irma to help me with that area. Put the debris pile on top of it and by the time it was picked up, mostly everything was dead underneath. It made it easy to pull most of the roots out then. So for the sprigs that have survived both there and in back, I take a can with both ends cut off, slip the weed inside of it (Beggarweed and/or Torpedo), and try to protect the surrounding St. Augustine as I spray the Roundup. My condolences to anyone battling this... good luck!

Dchall, I will take some pictures and post. I am unaware of anything buried there but definitely no stumps or rocks. Funny you should mention that. During a recent home addition, my plumber found a chunk of concrete buried in the back yard (different area) from when the house was built in 1992. I am mowing at the mowers highest setting. My watering regimen is by the book, one inch deep and infrequent. I sent a soil sample to LL last week so the results should be in later this week.

Literally everyone who writes in here from Florida is watering every day - literally every day. Literally everyone with no exceptions, except you. Thank you for that. I'm sort of familiar with the Maseca products. I think the instant one is the right one. Their labeling could not be more confusing - at least to me. When I see the word instant, I start thinking all the additives are in there so you just add water, but not with Maseca.
