Didn’t work as advertised
Would Not RecommendI only chose two stars in case I somehow didn’t apply the product correctly. I followed the instructions to the letter and three weeks later there were plenty of weeds growing out of my mulch beds. I’ll keep looking for another solution to prevent weeds from taking over my garden.
