What weeds?!

I have been using Preen for years, and it is the only weed prevention product I trust. Easy to use, easy to determine where it has been applied, and works great and lets me stay in bed on the weekends.

Worked like a charm!

I was so excited to use this because I absolutely hate pulling weeds! I mean, who really does. I followed the directions and boy, this really works!

This stuff is top notch!

I am so glad I was able to give this a try. It has performed beautifully. The area it's being used was always our problem area. Now it's our most talked about area. I have recommended this to several people.

Works great!

I sprinkled this on top of our freshly laid mulch and it worked wonderfully. Normally, I would be pulling weeds weekly but this prevented any weeds from coming through. I will definitely purchase again!
