The Q&A Archives: How do I control the weeds growing between my patio stones?
Question: I have not been able to control the weeds growing between my patio stones. There is moss growing between some of them and I would actually be fine with just moss, but every year there is a wide variety of weeds growing as well. I have tried Roundup, vinegar and just old-fashioned weeding. Can you suggest a solution that will be permanent?
Answer: You might try using a pre-emergent control such as corn gluten sprinkled between the stones. Reapply as directed on the label for best results.
