Good color, wet and dry.

Would Recommend

It’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 Recommend

The 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!

Would Recommend

We love Preen! A neighbor suggested we try it LAST YEAR so we didn't hesitate THIS YEAR!! It works. At my age, I just can't weed all of my flower beds every weekend that I'm home. Preen does the job for me, inviting the weeds to leave before I can ever see them. THANKS for such an awesome product!!

Keeps weeds down as advertised!

Would Recommend

Costs a bit more but well worth it. It keeps the weeds down as advertised. I have been using it for years with the same constant results.

product fine, staff unacceptable

tried to get 30 bags of this today, after walking past 5 Lowes employees seemingly playing with the completely gratuitous 'fence' around items in the parking lot i waited for 15 minutes to get a cashier to ring up 30 bags of mulch. then i went to loading, no one there, no big deal, happy to do it myself. no product. walked the whole lot to confirm all they had was inside. finally found an employee and said hey, all you got is sorta 30 bags on a pallet inside (lots of tapped up bags and they onl...

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!
