The 5 Best Natural Weed Killers and Preventatives You Can Find on Amazon

There are few things quite as frustrating as discovering a bunch of weeds invading your garden beds or pristine lawn. When non-chemical options such as pulling unwanted plants by hand or smothering them with mulch aren’t possible, you may decide to reach for a weed killer. But there are so many kinds to choose from; it can be a bit overwhelming. And some contain harsh synthetic chemicals that can be harmful to more than just your target weeds. Fortunately, many natural weed killers that contain less toxic ingredients such as vinegar, soap, or salt can help you keep unwanted plants under control with less worry about using them around your family and pets. These products may not work as quickly as synthetic herbicides, but they can still deliver the desired result when used consistently and correctly, according to their labels. Here are the best natural weed solutions, conveniently available on Amazon.

Best Overall: Green Gobbler Weed Killer

Made with 20% ethanol-distilled vinegar, this effective weed killer will eliminate persistent chickweed, clover, and more. The multi-use formula is four times stronger than table vinegar alone. Use the included trigger spray to soak the leaves of unwanted weeds. Make sure to avoid surrounding desirable plants or grass, which also can be damaged by this product. Within 24 hours, you should see results. Be sure to keep the bottle in a dry and cool area for future use.

Not only will this product kill these unwanted plants, but it can do so within 24 hours of initial use, so you can see the results you want quickly. The easy-to-use spray container doesn’t require any additional diluting or mixing and is ready to treat driveways, flower beds, wells, rock walls, and more straight from the container. For best results, spray this weed killer on warm, sunny days.

Best for Lawns: EspomaWeed Preventer

Espoma Organic Weed Preventer is made from corn gluten meal, which won’t rid your yard of current weeds, but it can work as a precautionary tool. When used correctly, it dries out the roots of annual weeds as they start sprouting from seeds and prevents them from growing. This product should be used twice annually, once in the spring and again in the fall. It not only discourages weeds from growing, but also provides nitrogen to your lawn. This nutrient will make your grass appear greener and more lush right after you apply it. Plus, your kids and pets can safely play in your backyard immediately after application.

Best Multipurpose: Calyptus Pure Vinegar

Like the Green Gobbler Weed Killer, this formula from Calyptus uses concentrated vinegar to eliminate unwanted grass and other weeds. According to the label, it’s useful beyond the garden, too; it can be used to clean stainless steel, remove soap scum from bathroom tile, freshen up your patio, and more. Just be aware that it’s much stronger than table vinegar, so it is not safe to swallow and you should avoid breathing it in or getting it on your skin because it can cause burns.

Best Fertilizer Combo: Safer Brand Weed Prevention

Like the Espoma brand product, this preventative option is 100% corn gluten meal. The convenient pellets will both deter weed sprouts and feed your shrubs, lawn, flower beds, or vegetable garden. Happy customers say it is “amazing,” “easy to apply,” and a “safe pre-emergent.”
