Remove Existing Weeds

Remove any existing weeds, taking care to remove their roots. Preen Extended Control products for landscape beds do not kill existing weeds.

Mulch the Area

A three-inch layer of mulch helps retain soil moisture, keeps soil temperature even and looks nice and tidy. Mulch also has preventative properties of its own, assisting Preen in keeping weeds away.

Apply Preen

Sprinkle Preen on top of mulch. Apply when the garden is dry so Preen Extended Control granules won’t stick to wet plant leaves.

Water To Activate

After applying the Preen Extended Control product, water the granules to release the ingredient that forms an invisible barrier that blocks weeds beneath the surface.

So Far, so Good
4 Stars
So Far, so Good
I've used in the past, seems to cut the weeds way back. We still lay down grass clippings down after I apply preen in the garden areas. Better than nothing, easier on the garden than round up or others etc.that kill more than the weeds.
