Questions & Answers

is this product harmful to pets
Asked by Woo June 24, 20202
AnswersSorry, I'm unable to answer the question concerning "if Preen is harmful to pets". However, the Preen containers state in red on the outside "Keep out of reach of Children." and I wouldn't use it where pets could access it.

Asked by jewels April 14, 20203
AnswersI have never considered to the ground temperature but the product has always been effective for me. Presumably that information can be obtained from the manufacturer if it is not on the product container itself.
Is this the largest size container?
Asked by Gramcrackergran April 14, 20204
AnswersThis is the largest container that I have ever been able to order or buy in store. Perhaps landscapers have access to larger volume, but I do not know about that. Preen is scattered fairly sparingly and I feel that it is very good value for money.

Great product
July 9, 2020
I use this product every 3 months on my mulch beds and I have minimal weed issues. I have been using this product for 4 years and my mulch beds look fantastic. This container is nice to buy it cheap. Once I'm ready to put preen down, I dump this bulk container into the smaller preen container with the spout for easy application. After I apply preen to the mulch, I water it in. This product has met my expectations and I have not had a reason to dislike it.
By spreading Preen throughout my garden, I am literally weed free.

Waste of money. Doesn’t work.
May 10, 2020
Customer review from preen.com 
We bought two huge buckets of this stuff every year for the past 3 years from Costco. It has never ever worked. Don’t buy. Doesn’t do anything. We pulled all existing weeds, put Preen down and a month later we have hundreds of weeds (dandelions, vines, thistles). Stuff is garbage. Waste of money. Will never buy again.

Customer review from preen.com
I bought Preen for my front garden. Being disabled it is hard for me to weed. I'm so happy with the results of Preen,my garden is weedless and no pain for me from weeding. This is a fantastic product and I have recommended it to all my family and friends. Wish I would have used it the past years. Thank you for such a wonderful product.

A Lifesaver!

Customer review from preen.com
I began using Preen over 15 years ago when I decided to increase my flower beds. It was so difficult trying to control the weeds until I used Preen. With so many flower beds I needed a partner to help me weed and Preen became my new best friend!!! When I moved, I cried leaving behind all my beautiful gardens. So at my new home, I did the same thing. Began using Preen and have my old freind working with me again. I use it about 3-4 times per year in my beds and my weeding is minimal. I cant say enough about it! I have recommended Preen to my new daughter in law, as I help her begin her flower gardens. Thank you Preen♥ [This review was collected as part of a promotion.]
Results were what we needed!
May 30, 2017
Customer review from preen.com
We bought this for a garden in a county park in Michigan. We needed something to keep the weeds at bay as there are many things that fly around in the parks! Not only after 6 weeks were there only 3 weeds but the plants are growing nicely without weeds to cut them back! [This review was collected as part of a promotion.]
A must
May 30, 2017
Customer review from preen.com
This product is excellent. Could not maintain my gardens without it. Kills the weeds without having to do anything. Saves me tons of work weeding so I have more time to enjoy the gardens. If you do any kind of gardening, this product is a must. [This review was collected as part of a promotion.]
No Weeding

Customer review from preen.com
I use Preen in multiple shrub beds around my house and Koi pond and rarely have to pull a weed. Apply to mulch early spring and several times during the season. [This review was collected as part of a promotion.]
Preen Weed Preventer

Customer review from preen.com
I have used this product & the one similar made by your company. I liked it & the difference it made compared to other products. As a Master Gardener I don't always get wooed by products & don't want more in my garage. I have not tried the other Preen products. Perhaps I will soon.
