RoundUp is NOT good for a year. It only kills what is there and growing when you spray it. It is a contact herbicide, not one that stays in the soil for a year. FWIW, the ones that say "keeps weeds from growing for 12 months" is not true either. The Spousal Unit sprays that along the electric fencerows to keep the weeds down. He's lucky if it lasts the summer. We farm.............I know something about herbicides.
