| How early is using roundup effective? I'm thinking since it is going up to 70 degrees tomorrow, and weeds are growing it should work, but I would hate to waste my time if I should wait another week or so. |

| No need to wait for higher temps for this particular product. As long as the target weed is green and not frozen, it should work. Cold or cooler temperatures will slow the action way down, however, so patience is needed if applying early in the season. |
