A.D.I.O.S. Eco-Friendly Weed Control

For a truly organic approach to killing weeds, this OMRI (Organic Materials Review Institute) -listed natural weed killer by A.D.I.O.S. is a great option. The post-emergent herbicide is a concentrated solution that requires mixing with water prior to use. It’s non-toxic and odorless, and once sprayed, immediately travels to the root of the weed to work its magic. It’s safe for use around kids and pets.

“Just tried this out on several types of weeds in my grass and worked like a charm!” says a reviewer. “All the weeds I sprayed are now black and wilting in less than 12 hours. I used a 1:1.5 ratio. I think it is important to follow the directions by shaking it well before pouring into your sprayer and make sure to use it on a sunny day with no rain in the forecast. Very happy knowing my child and pets will not be rolling around in toxic chemicals found in all the other weed killers out here!”

Doctor Kirchner Natural Weed Killer

What makes the Doctor Kirchner Natural Weed Killer unique is that it’s made from ocean water, vinegar and soap. Reviewers love its ability to make weeds wither and turn brown in just a few hours, without the use of harmful chemicals.

“We mainly use it on the rocks in our landscaping when weeds pop up around our bushes and flowers,” says a reviewer. “Within a half hour, the weed is shriveled. By morning, the weed actually seemed to disintegrate into the rock. I could hardly even see it. Normally, we have to go back and pull up all the dead weeds after using the RoundUp. I don’t have to do anything after spraying. It’s awesome!”

Armor via amazon.com

Natural Armor Weed and Grass Killer

Made with no chemicals or poisons, including glyphosate, a widely used herbicide that controls broadleaf weeds and grasses and has been linked to cancer, Natural Armor Weed and Grass Killer is an all-natural concentrated formula that works on 250-plus types of weeds and grasses. You’ll begin to see results in hours. The ready-to-use product requires no messy mixing or diluting. You simply spray and watch the weeds wither.

“This stuff worked GREAT!” says a reviewer. “I wish I took before and after photos because it was truly impressive how well this product worked. We had a few different kinds of weeds sprout up in our backyard and were sick of spending tons of time pulling them out one by one but that was our only option with two dogs. I didn’t want to use any big brand sprays with fear that the dogs may get sick. I sprayed this on them [the weeds not the dogs!] and saw a difference within a few hours, 3 days later and all the weeds are 100% dead – and this was with some light rain the day after application. I like that it’s all natural. After it dried we let our dogs out and haven’t noticed any signs of skin or intestinal upset. Would purchase again!”

Weed Slayer Organic Herbicide Natural Grass and Weed Control

An effective (and expensive!) natural weed killer, Weed Slayer Organic Herbicide is a plant-based herbicide derived from eugenol, an essential oil of clove. The natural and safe alternative to glyphosate kills the weed from the root. Skeptics of all-natural weed killers were pleasantly surprised with its results.

“Alright, I thought, ‘Here’s another organic herbicide product that won’t work, but ok, lets see if it’s for real,'” says a reviewer. “Much to my surprise, when I mixed the 2-part product, at 3 oz of each per gallon, I could not tell the difference visually between an area sprayed with Round Up and one with Weed Slayer. It took about 6 days for the weeds to start going down but at 14 days they were toast.”

Help the planet and use this instead of the other toxic crap.”
