Would Recommend[This review was collected as part of a promotion.] This product did a great job at killing the weeds in our lawn. This is much more cost effective than getting a weed control service.

I finally won!
Would Recommend[This review was collected as part of a promotion.] Northern MN does not have great soil and it is a challenge to grow anything. The one exception is the dandelions; they are like non other. My yard had dandilions that simply laughed at me when I put down other products. With Preen I now have respect from these pesky weeds. I finally won! We won't even consider another product going forward.

Would RecommendI have recently use the product, it seem,s pretty tasty to the small critters also, should have downloaded pic,s but the weeds are dead so enough said, is there anything in the preen that would make them peck or chew through the bag?

Great for Ditching Weeds
Would Recommend[This review was collected as part of a promotion.] It's springtime, and my lawn gets treated with Preen every year. It looks great, because Preen does a super job eliminating weeds.

AMAZING!!!
Would Recommend[This review was collected as part of a promotion.] I just though I would try the Preen Lawn Weed Control because of the over 200 weeds it would kill, truthfully I didn't want to get my hopes up & I did not expect to much. I WAS SO WRONG! I work in a lawn & garden dept. (plants are my specialty Not Lawns) & I Very Highly Recommend Preen to Everyone that asks me what they should use on their lawns! Preen is my 1st Choice & Only Choice! I truly believe in this product! I am not a fan of the other...

deficiences in Preen
Would Not RecommendI've used Preen for years on borders and gardens. It does nothing to prevent the spread of Creeping Charlie, which is the number 1 weed pest in this area. Preen is expensive and not effective.

Very Effective !
Would Recommend[This review was collected as part of a promotion.] Since I live in a house that is over 100 years old I am constantly combating weeds in between our brick walkways and panels of sidewalk. This is the only product I have found that will not only kill the weeds but prevents new growth for several months.

Worked great for us!
Would Recommend[This review was collected as part of a promotion.] Weeds are very hard to control on our mountain ranch. We only try to moderate the ones in the immediate vicinity of our home. This Preen Weed Control took care of all of our weeds in the front and back lawns lat year. What's more, very few tried to make a come back this year.
