6 Best Organic Weed Killers That Are Safe For The Yard Ft Via Getsunday.comVIA MERCHANT

An organic weed killer is one of the most effective, natural ways to eradicate weeds from your lawn, garden or outdoor space.

Killing weeds is a yard maintenance task you don’t want to neglect, and the best organic weed killers are made without toxic chemicals like glyphosate. Instead, they feature natural components such as vinegar, essential oils or an herbicidal soap solution.

Bryan Clayton, CEO of GreenPal, has two decades of landscaping industry experience and knows a thing (or two) about herbicides.

“It’s essential to use an organic weed killer,” Clayton explained.

But how do you know if weed killer is truly organic?

“Certified organic products typically display a logo from an organic certification body,” Clayton explains. “You should also look for a comprehensive list of ingredients. I’ve found that organic weed killers generally contain only natural ingredients, like vinegar, salt, or citrus extracts.”

While there are multiple ways to learn how to eliminate weeds, employing a weed killer that’s safe for use around kids, pets and outdoor vegetation is a game changer. Not only are they safer for your family and pets, but “they are free from harmful chemicals that could potentially infiltrate your soil or water supply… and don’t add to environmental degradation,” Clayton says.

Here are the best organic weed killers that are safe for your yard, family and fur babies.

“I wish I took before and after photos because it was truly impressive how well this product worked,” writes verified Amazon reviewer Terri.

Best Organic Weed Killer for Lawns

Espoma Weed Preventer

Feed your lawn while also killing weeds with Espoma Organic Weed Preventer. Made from pure corn gluten meal, it’s safe for children and pets. We like that this product prevents weeds from growing while keeping lawns healthy and green. This weed killer has long-lasting nitrogen for a richer, thicker and greener lawn. So, its dual-action formula is a win-win for your lawn.

All it takes is two applications per year for this organic weed killer to work its magic.

“Some of my neighbor’s lawns have been taken over by crabgrass, as had one section of mine at this time last year,” Amazon reviewer Jane Discern explained. “However, after applying this product onto my lawn last Spring, the crabgrass has dramatically decreased, and I only had to dig individual, small clumps of crabgrass here and there, instead of large patches of the weed. It also reduced dandelions, and I read that, after a few years of application, the weeds will become non-existent, so it is now part of my Spring and Fall lawn-maintenance program.”

Pros

  • Prevents weeds from growing rather than killing at the source
  • Acts as lawn food
  • Easy to spread
  • Requires two applications per year
  • Safe for pets and kids to play in grass after it’s applied

Cons

  • Only works on lawns and large grassy areas
  • Won’t kill already existing weeds

Best Organic Weed Killer for Gardening

BioSafe Weed Control

As an organic-certified herbicide, BioSafe Weed Control quickly kills annual and perennial broadleaf weeds and grasses. We recommend this product for gardeners because it doesn’t leave residue, and you can plant less than a week after it’s applied.

For best results, BioSafe should be applied to weeds before they mature. While you’ll want to cover weeds thoroughly with the spray, you’ll also want to avoid contacting plants you want to keep. You’ll see BioSafe go to work within 1-2 hours of application as the leaves begin to brown. This product does not move through the soil or between plants, so you don’t have to worry about nearby plants being affected (as long as you don’t spray them).

Pros

  • Safe around walkways, flower beds and landscaping
  • Destroys weeds within hours
  • Water-soluble herbicide
  • Doesn’t leave residue
  • Safe around pets

Cons

  • Expensive

FAQ

Does vinegar kill weeds permanently?

Experts say that because vinegar is acidic, it will eventually kill most broadleaf weeds. However, vinegar will typically kill leaves before reaching the roots. Salt, however, dries out the weed’s root system. So, if you have an organic weed killer with salt and vinegar as ingredients, it should do the trick for more permanent weed removal.

Will grass grow back after vinegar?

The acidity of vinegar will temporarily scorch grass, but it shouldn’t kill grass completely. The same goes for weeds. Vinegar temporarily eliminates weeds, but they will eventually grow back from the roots.
