I am just a homeowner that decided to quit using herbicides and pesticides three years ago. I had my soil tested and it was low on nitrogen and too high on phosphorus and potassium. I top dressed my yard with compost, sprayed molasses, and spread soybean meal (heavily) spring and fall. My grass is now a dark green and has to be mowed every 5 days. This spring I had the best looking yard I've ever had. My problem is nutsedge-it is everywhere and getting worse! I can't find an organic solution. I read some people have had some success with molasses but it didn't work for me. Does anyone have any other suggestions?? Please help, it's making me crazy!
