Would RecommendIt’s midnight black is good. When it is applied it is very dark, but then it dries to the same color as the older chips we’ve laid down which is still a nice Black.

Don't do pay extra for Preen Mulch
Would Not RecommendThe Preen Black Mulch product itself was just fine. It spread perfectly fine. We cleared our bed from all weeds before laying out the black mulch. It's been about 3 weeks of summer heat and intermittent rain in Richmond, Texas. And lo and behold the weeds are back with revenge. Not sure if I can recommend paying all the extra money for this specialty product. Its didn't do as promised in keeping the weeds away.

It really does work!

Preen does the job for me, inviting the weeds to leave before I can ever see them. THANKS for such an awesome product!!

Hello and thank you for your comment. We are sorry you experienced this and we will share this feedback with our Lowe's partners to address these...

because of the delivery issue I am now boycotting Lowe's and I am also telling everyone I know not to shop at Lowe's
Bad Batch?
We have used Preen for years but this year 3 of the 20 bags had some type of seed in it as my beds had thousands of tiny sprouts growing in the mulch. I thought I paid extra money for mulch that kept OUT the weeds. Not the case this year!
