Preen Garden Weed Preventer 5.6-lbs. 900-sq ft Pre-emergent Herbicide

Preen kills myrtle

I applied Preen to a myrtle bed to hopefully prevent Japanese stilt grass from emerging. Killed my myrtle. I will have to have landscaper plant grass or cover with landscaping stones.

Great product

When spring comes, I weed my garden with a weed pole, easy, pick up some big ones, plant my new annuals and apply preen. No weeds grow. After a few weeks I turn my soil a bit with my weed tool and apply again. I love it. I like a weed free garden bed.

Love Preen

[This review was collected as part of a promotion.] I have used Preen for my flower beds for the last several years. I am elderly & cannot bend over to weed so this is a godsend. Last year I started using it in my vegetable garden. Since I only plant established plants it worked really well. Between using the preen & a muclh, my garden was a breeze to care for.

Wasted money

Purchased your product for years and have never seen it work so poorly. I even reapplied and still am spending hours weeding my garden. It's either a bad batch or they're reformulated and it's now a bad product.

Excellent Weed Preventer

I'm a PNW flower gardener and Preen works! It is truly a back and knee saver! Every January I check my flower beds for emerging weeds and moss & pull them out or hoe. Then immediately sprinkle Preen all over the clean soil avoiding emerging spring flower bulbs such as tulips, daffodils, iris, peonies, etc. Preen keeps my flower, herb and veggie beds weed free, especially before Easter when the spring flower "show" blooms! Many people stop by to walk thru my garden and always ask how I keep weed...
