It's worth the buy.

Would Recommend

After the first application I had to apply a little more in thicker weed spots. I used the product also last year and it controlled weeds for practically the hold summer. I'll get it 3 stars or a little better.

Effective Weed Control

Would Recommend

Granules are easy to apply and the bag is a better value than the containers. Definitely noticed fewer weeds on the area of lawn and parts of the flower beds I sprinkled it on, with no damage to the flowers. Preen is always or go-to brand.

Put down BEFORE weeds bloom, and when grass is WET

Would Not Recommend

Preen is listed as a PRE-emergent - so it didn't work well since weeds were 'already' growing, but i was hoping for the best.
