Dollar Weed Taking Over Organic Floratam
OK, here's my situation. I have a lot of dollar weed showing up in my new Organic lawn. About a 6 week ago I laid 2000sqft. St.Augustine floratam in my front yard. I prepared the soil by adding 5 yards compost/topsoil mix, 100lbs alfalfa pellets and 30lbs used coffee grounds.
After the sod was laid I watered in the early morning; twice daily 1st week, once daily 2nd and 3rd week, every other day the 4th week, every 3 to 4 days the 5th week, and currently only when needed. (about 1 in. every 5-6 days) The sod looks great now, I mow often and High (4in.) using a recycling mower.
I don't know what to do about the Dollar Weed, it just keeps spreading. Is there anything I can do to stop it Organically?
