Will grass grow back after spraying with Roundup?
Grass killed by Roundup will not grow back from the root. Roundup is a very effective chemical herbicide that kills all varieties of plants completely. If a grass plant is brown 14 days after Roundup has been sprayed on it, then it will not come back. Roundup kills grass completely—preventing regrowth from the roots.
