Preen

Preen helps keep down weeds in my flower beds and feeds them at the same time. Good product!

No summer weeding

Once you rid your garden of active weeds, spread Preen in your garden as directed an you will not have to weed again. I have used this for years. The container size at Sams is gigantic. It has saved me from many hours of garden weeding,

Great weed prevention for rock landscaping

Preen is a must-have each year for the rock landscaping in our yard. It makes a huge difference in keeping weed growth down and is very easy to apply a few times per year. If we don't do the application early enough in the season before the weeds germinate, we get weeds galore. This stuff really works!! The value pricing through Sam's was awesome as well. Highly recommend!
