Dress in long pants, a long-sleeved shirt, socks and closed-toed shoes. The clothing will help to protect your skin if the hot water splashes onto you.
Fill a teakettle with water. Heat the water on a stove burner until the water boils. The water needs to be more than 200 F.
Place an oven mitt or heavy-duty glove on your hand. Turn off the stove burner, and remove the teakettle from the stove. Carry the teakettle immediately but carefully to the weeds you want to kill. Don’t waste time getting to the weeds because the water temperature drops quickly, and it’s the heat that kills them, says a guide from Thurston County, Washington.
Weeds quickly multiply, making a landscape look sloppy and stealing nutrients from desirable plants. Chemical weedkillers are an option to get rid of weeds, but their potential for negative environmental and health effects leads many homeowners to seek natural options. The boiling water treatment is inexpensive and effective in burning weeds. Hot water works better on broad-leaf weeds than it does on established perennials, woody plants and grass, according to University of California Integrated Pest Management Online.
Identify the weeds you plan to kill using the boiling water method. Choose weeds that aren’t near plants that you want to live. If the boiling water hits a plant, that plant probably will die. Boiling water often works best on weeds along sidewalks and driveways, away from other plants.
Today we’re going to show you another way of killing weeds. We’re going to boil them. The theory here is that we are not only going to kill the plants above the ground but that the water and the heats can transfer down and kill the roots as well.
Boiling water is certainly an appealing alternative to toxic herbicides: it’s free of harmful chemicals, it’s cheap, and it kills weeds. Yet, piping-hot water isn’t the best weed killer in every situation, because the super-hot liquid kills not only weeds, but also any vegetation surrounding it.
Things You’ll Need
Survey your sidewalk and driveway to identify the weeds you can cook without running the risk of killing other plants.
Boil water in a kettle with a narrow spout so when you pour your hot water on the weeds, it doesn’t splash on anything else.
Even if you cover your other plants with a plastic cup to shield them from the scalding water, you can’t protect them underground. For this reason, reserve the boiling water for weeds growing out of cracks in the pavement or driveway, far from desirable plants.
