To the Image Gallery

If you hate to pull weeds, you are not alone. Weeds top the list of lawn and garden problems for 59 million American households, according to the 2018 survey What Gardeners Think. Fully 57% of gardeners surveyed named weeds as, by far, the landscape challenge they struggle with most.

It doesn't have to be that way. Many use Preen weed preventers as a secret weapon against weeds. They simply sprinkle product granules on garden and landscape beds to create an invisible barrier that blocks new weeds from growing. Now, the longest lasting Preen weed preventer yet is available nationwide. Preen® Extended Control™ Weed Preventer blocks weeds for six months, guaranteed


Preen weed preventers block weeds as seeds – before they start growing. Typical garden soil contains millions of buried weed seeds. They sit dormant, waiting to be dug up and exposed to light. That’s all it takes to spark growth. Ironically, there's one common activity that regularly breaks the soil surface exposing weed seeds to light – weeding! Pulling weeds creates more weeds. It makes you feel like you just can't win.

Except you can. To break the weeding cycle, apply Preen Extended Control Weed Preventer in early spring, summer or fall. Use it around established plants, including listed perennials, trees, shrubs and groundcovers in landscape beds, xeriscape settings, gravel areas and rock gardens.

  • This is a weed preventer, not a weed killer. First remove existing weeds,
  • Sprinkle the granules on top of the soil or, better, on a layer of mulch,
  • Water it in to activate the weed barrier (or apply before rain),
  • Preen Extended Control Weed Preventer blocks listed weeds for six months, then biodegrades. It doesn't persist in soil or leach into groundwater.

Available from local and national garden retailers and online, it comes in three convenient sizes: a 4.93-pound jug-handled bottle with flip-top applicator cap that covers 805 square feet, MSRP $19.99; a 10-pound bag that covers 1,630 square feet, MSRP $34.99 and a 13.75-pound pail (with applicator scoop) that covers 2,245 square feet, MSRP $44.99.
