Why buy multiple weed killing products when you can have one that does it all?

What's more, you can apply this weed and grass killer to both hardscapes and landscapes. Treat your landscaping and hardscaping at once, then enjoy the greenery for the next few months worry-free.

It is important to understand the basics of any weed and grass killer to avoid application error. We have compiled a list of all the places you can (and can't) use Roundup® Dual Action Products so you can apply with confidence and achieve a beautiful outdoor space.

Where Can I Use Roundup® Dual Action Products?

Roundup® Dual Action Products can be used in a variety of settings:

  • On crevices and cracks in driveways, sidewalks, patios, and walkways
  • On gravel areas
  • In mulched beds
  • Around the base of well-established trees, plants, and shrubs (at least six months old)
  • Between pavers
  • Under decks
  • On parking areas
  • Along fences
  • Along foundations, curbs, and retaining walls

Where Should I NOT Use Roundup® Dual Action Products?

We recommend that you don't use Roundup® Dual Action Products in areas where you want vegetative growth, such as:

  • Lawns or for lawn renovation as this product prevents desirable grasses from growing, too
  • Landscaped areas around young plants (less than six months old) or areas that will be planted and seeded within four months
  • Plants or grasses you like—they will die
  • In or around vegetables or fruits, including vegetable gardens
  • Along fences, if desirable plants or grasses are on the other side, such as a neighbor's ivy or privacy hedge

It's Go Time

Now that we know where to apply, it's time to treat those areas. To have the most control over where you spray, we recommend Roundup® Dual Action Weed & Grass Killer Plus 4 Month Preventer with Sure Shot® Wand. The protective shield of the Sure Shot® Wand allows you to use Roundup® Dual Action Products to kill unwanted weeds right down to the root while comfortably guarding the desirable plants. The shield keeps the spray contained so wind won't carry it to desirable plants. And the extra long wand lets you treat weeds with ease.
