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.

Buy It: Espoma Organic Weed Preventer ($50, Amazon)

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 essential 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

Buy It: Calyptus 45% Pure Vinegar ($25, Amazon)

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

Buy It: Safer Brand Weed Prevention Plus ($29, Amazon)

Like the Espoma brand product, this preventative option is 100% corn gluten meal. The convenient pellets will both deter weed seeds from sprouting and feed your shrubs, lawn, flower beds, or vegetable garden. It does need to be applied before weeds appear because it won't affect already growing plants. Happy customers say it is “amazing,” “easy to apply,” and a “safe pre-emergent.”
