I hope you don't have this problem but if you selected my blog you probably do!! Sandburs or also known as grassburs are multiplying rapidly in our pasture and yard and can't even let the grand children loose out there without them getting hurt by the stickers. I've been trying to find an answer to our problem! I went to Texas A&M Agg. dept looking for some answers and here is a great report on controlling this obnoxious weed! I hope this website helps you also!
