The recommendation is to wait one to three days after applying glyphosate to plant grass, herbs, or fruit. It mostly depends on what else is in the herbicide.

The recommendation is to wait one to three days after applying glyphosate to plant grass, herbs, or fruit. It mostly depends on what else is in the herbicide. You might wait a week for the previous plants to really die before cutting them off. When replacing areas of random noxious weeds with grain I wait three days after the glyphosate and have no problems with my regular old, low tech oats or barley. (I do grain because it gets tall kind of fast and helps choke out the next batch of weed seeds waiting to sprout, the birds like it, and it’s pretty when it gets dry and wavy.)
