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!

Love to buy this in the big bucket, it will keep for a couple of years and prevents weeds in the flower beds, saving my back from the pain of pulling them.

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,

I'm using Preen in my garden beds to help prevent weeds from coming up in the mulch!

Best price for the product I wanted

We have used Preen for years. It saves a lot time by preventing weeds for the entire summer. This large package was the best price I found. I recommend buying the hand held spreader. It makes getting an even application easy.

Great weed protection

Good product

I was really excited to try with for my fire pit area. But it didn't work at all. I'm wondering because it is covered in rocks and not dirt? I did water pretty good after. The weeds just come thru so bad. I had to get a spray.

Weeds are growing right through this. Disappointing
