Why people love Preen for their gardens

Saved me DAYS of weeding!!!! I have been using this product for the last five years and it has never failed to stop weeds for at least two months before I have to reapply.

I'm a true believer in Preen. I have been using Preen in my garden for the last 5 years. I heard from a fellow gardener that Preen worked really good so I decided to give it a try and I am so happy that I did. I don't have to continuously fight weeds and my garden looks great!

Weeds Be Gone! Love this product. I have used it for several years and my walkways and flower beds have been weed free! For me it has been a life saver. Thanks Preen!
