I live in Merritt Island, Fl=L and used a weed and feed on my lawn, but the Oxalis was not killed and instead is thriving! What product will work for this now post emergent weed?
Celsius WG Herbicide is a post-emergent herbicide that is safe to apply to your St. Augustine lawn and is labeled to eradicate oxalis (yellow woodsorrel).
