How soon can I reseed after spot treating with Roundup?
I am about to spot treat some Canadian Thistle in my lawn with Roundup. I have been mowing it down for two summers and it is laughing in my face and sending shoots to my garden beds. I am sure I will get a few bare spots with the treatment, and I am wondering how long I should wait before patching the lawn with seed. I want to get it going as soon as possible after the thistle is dead, because I am in Michigan and first frost can come early! Can I plant right away or should I wait a while?
