Yes, your lawn is manicured and beautiful and your lawn care regimen is polished to perfection, but did you know that such care can actually make a lawn more susceptible to weeds? Dandelion, crab grass—basically anything with a seed—loves to work its way into neatly clipped grass and Pinterest-worthy gardens.
One natural weed killer to keep those unsightly greens at bay? “Keep the lawn long, so it takes longer for seeds to work their way down the ground,” says Leslie Reichert, founder of Green Cleaning Coach. Or try the old-fashioned, labor-intensive method: “Sometimes you can’t control exactly where the weed killer disseminates when sprayed. If you’re afraid of brown spots in your lawn, a weed puller and a bucket can be your best bet.”
For something a little stronger than old-school weed pulling, but still natural and toxin-free, try these do-it-yourself, homemade weed killers to wage the war on weeds with ingredients most likely laying around the house.
Homemade Weed Killer | Try this homemade weed killer as part of your spring lawn care: a gallon of vinegar, a cup of salt or Borax, and a tablespoon of dish soap. To apply, use a spray bottle where you can toggle the nozzle between a spray or a stream. If it’s a small area, shoot a stream; if it’s an all-over weed situation, go for the spray. Don’t go crazy, though.
“Be careful with it,” Reichert advises. “It doesn’t know the difference between a weed and a flower.” Especially when using the more potent Borax (a naturally occurring substance that doesn’t cause lingering harm to an ecosystem or absorb through skin), the solution can also kill the soil so that nothing else will grow around it. This method works best on a sunny day, as the natural acid will burn the plant and the salt will shrivel it up by sundown (the dish soap helps the solution stick to the weeds). For a quick curb appeal fix, this one is also lasting.
Newspaper | Even professional landscapers are known to use this simple, natural weed killer. If your garden is infested, use a weed whacker to address the culprits, then lay down yesterday’s headlines. Newspaper blocks beginning weeds from growing and new seeds from forming by shutting out sun and air. Top it off with mulch and the weeds won’t show up, Reichert says. The newspaper will break down eventually, too, so there’s no clean-up.
Note that boiling water won’t kill the weeds at their roots, according to Chris McGeary, chief marketing officer at Lawn Doctor, a lawn care company. This option isn’t a permanent one, as the plants can grow back, so use it only as needed. And, of course, take safety precautions to avoid burns.
