“I received Preen Extended Weed control about the end of March. It is now May and I haven't seen a weed yet! I like this product a lot better than the weed killer. No ugly brown spots and no weeds!”

Carter

“Works great! I used this around my flowers, where I was afraid to cut with the weed eater and it worked wonders. Very easy to use, too. I am also glad it did not have a harsh smell as a lot of weed killers do, this one was not over powering.”

I used Preen Extended Control near the end of March. It’s now May and I haven't seen a weed yet! I prefer this product over a weed killer. With Preen Weed Preventer, you don’t need to pull the weeds and it takes care of the rest! No ugly brown spots and no weeds!
