Answer: If the nutgrass is truly an annual that sprouts from seed, you can apply a great organic control from Gardens Alive called WithOut Weeds. It's just corn gluten, a by-product of corn processing. An enzyme in the gluten inhibits seed germination. This won't affect the spread of St. Augustine grass, which propagates primarily via runners. Corn gluten also contains nitrogen and other nutrients, so it's like a natural "weed-n-feed", only better, because it's safe for all creatures except seeds! You can cut back on your next fertilizer application, too. Contact Gardens Alive at firstname.lastname@example.org or ph# 812/537-8650. Good luck!
