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!"
Green Gobbler Vinegar Weed and Grass Killer
In less than 24 hours, you can eliminate any type of weed with this natural weed killer. Containing 20-percent acetic acid, it's safe to use anywhere. The product is four times stronger than traditional table vinegar, is void of VOCs or other harmful additives, and is made from ethanol distilled completely from corn grain. The result is a green product you can trust to get the job done sustainably.
"We really like the Green Gobbler Vinegar," says a reviewer. "This is the only product we use for killing weeds! Natural and organic and your yard smells like a salad for a day or so. Kills weeds within a day. Plus, you can dilute to 10% from the 20% vinegar to stretch it out!"
Doctor Kirchner Natural Weed Killer
What makes this 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!"
BioSafe Weed Control
An organic herbicidal soap, this natural weed killer works on annual and perennial broadleaf weeds and grasses within hours of application. This non-volatile, water-soluble herbicide is completely safe to people, pets and the environment. One reviewer claims they would give it 10 stars if they could!
"HATE Roundup. We finally said no more many months ago and the weeds were crawling everywhere! We have tried many different types of weed control — even some DIY formulas. But THIS WORKS!!!!!! Easy to mix, safe and the weeds are DEAD. You can see the damage done within hours, even grass."
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, this natural weed 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!"
Aceta Force 30% Natural Acetic Acid Vinegar
This natural weed killer is free of harmful ingredients, such as glyphosate or petroleum. Made from distilled white vinegar, it contains powerful, natural acetic acid that's derived from corn grown in the United States. Reviewers rave about its ability to kill weeds without harming the environment, their pets or their own health.
"I purchased for a weed killer alternative to nasty chemicals. This did the trick," says a reviewer. "I used full strength to spot treat some weeds growing in the rock bed around the perimeter of house. The next day, even with a fair amount of Florida rain the weeds were dead!"
Branch Creek Pre-Emergent Weed Killer
This natural granular fertilizer is a pre-emergent herbicide that controls broadleaf weeds. Free of toxic, synthetic chemicals, it is 25(b) exempt, meaning it's a minimal-risk pesticide that doesn't need to be registered with an EPA number. What's extra enticing about this product is that it contains 10-percent nitrogen, which promotes quick greening and lush turf.
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."
Dr. Earth Final Stop Weed and Grass Killer
This weed and grass killer spray contains essential oils and organic acids among its list of natural ingredients. The effective herbicide is safe to use around your family and pets. Reviewers note that while it is effective, it requires a bit of patience.
"Product works but it takes about three weeks. Be patient. One gallon covers about 500 to 1000 square feet. Kills everything!"
Avenger Organic Weed Killer
This herbicide contains citrus oil, which naturally strips weeds of their waxy plant cuticle. This process dehydrates the weeds, causing them to die. The effective natural weed killer works fast, with noticeable results in less than two hours.
"It works great and I don't have to worry about having to spray toxic Roundup all over my property," says a reviewer. "I buy this every spring to tame my weeds. Be careful and don't get it on anything that you want to live. It kills everything. It has a nice smell too unlike Roundup and other super toxic herbicides. Help the planet and use this instead of the other toxic crap."
