Pet-Safe weed killer
Hello! Thanks for reaching out to OSU Extension.
While nothing is 100% safe, there are several low-risk options.
- It can get pretty hot in the summer months next to pavers. If you can keep your irrigation water off the pavers, the weeds may die from heat stress.
- Flame and boiling water are options to kill the tops of weeds, but of course, not very safe. Handling practices would be very important to reduce the risk.
- After clearing the weeds, a pre-emergent weed killer, when used according to the label, could be very effective at preventing future break-throughs. There are several options on the market at hardware/big-box stores. Look for the word "pre-emergent" on the label and follow the directions carefully. Any excess runoff could prevent turf/plant growth nearby.
