Preen Extended Control Weed Preventer, 10 lb bag covers 1,630 sq ft

This has really helped prevent weeds in my flower bed. While it doesn’t prevent weeds that are already established, it worked great for preventing future ones.

Works great! I especially like it for landscape areas where I have gravel and don't want weeds for long periods. It also doesn't seem to bother the mature plants.

I have been using preen for many years on my flower gardens and was thrilled when I saw one that lasts for 6 months. I put it down at the end of end of April and it will keep weeds away through the end of October. Having 7 gardens and knowing I won't have to weed is a wonderful thing - I definately recommend this product, it totally works.

I have used this product for years and it does get rid of weeds! But I have recently found a new use. I have an irrigation system for my yard and the grass and weeds grow around and over my sprinkler heads and then they cannot pop up as needed. So, I sprinkle a little extra granule around my sprinkler donuts and now I no longer need to hand weed around them every few weeks, ingenious.

Great product - has reduced summer weeding 90%
