Doesn’t hurt your plants

Weed Watcher is safe to apply to your lawn and only targets unwanted weeds.

Works quickly

Easily spray on Weed Watcher, then watch as targeted weeds quickly wilt and give way for easy removal.

Safe ingredients

Weed Watcher uses iron to quickly kill weeds, unlike many traditional weed killers that use harmful synthetics.

How Weed Watcher works

Weed Watcher is a selective weed killer that’s safe for your lawn while controlling weeds. It’s specially formulated with chelated iron (a safer alternative to other weed killers) which causes the weeds to wilt and die off while plants around them (like grass!) remain unharmed. And you don’t need to wait around like with other weed control treatments – once Weed Watcher has dried onto your lawn, your yard is ready to go and is safe to enjoy!

  1. Shake up the bottle. No need to dilute!
  2. Spray weeds thoroughly. Use the course nozzle setting to easily target weeds and make use of every drop.
  3. Enjoy & Repeat. You can get back to enjoying yard yard as soon as Weed Watcher has dried. Apply every 3 to 4 weeks for best results.
