If you’re done with your patchy, high-maintenance lawn, this one’s for you
There are perfectly understandable reasons for wanting to get rid of the grass on your lawn. Maybe it’s full of weeds that are impossible to control. Or you want to pull it up in order to install a low-maintenance lawn alternative. Whatever your reason, here are some ways to kill your grass.
And if you want to keep your lawn, consider this a guide for what not to do.
For a healthy lawn, experts recommend keeping grass over 3 inches tall. Slightly longer blades give the plant nutrition and help it manage moisture and temperature. So, if you want to kill your grass, cut it as short as your mower will go. Cut it several times, making sure to bag any clippings that would give the lawn good nutrition—this is not the time for grasscycling.
Herbicidal vinegar, or acetic acid, is much stronger than the vinegar you use on a salad and it’s not for human consumption. Herbicidal vinegar will do a number on your lawn. So, if it’s lawn removal you’re after, give herbicidal vinegar a try. Be sure to wear the proper protective equipment and follow the instructions on the label. It might take a couple sprays and several weeks to kill all the grass.
After mowing your lawn on the shortest setting, cover the lawn with a dark plastic tarp or a sheet to smother it. Letting it roast under the summer sun while starving it of rain is a surefire way to kill the grass. If you go this route, make sure to anchor your tarp down with bricks or other heavy objects so it stays in place on windy days. It could take several weeks to kill the lawn thoroughly.
If you want the lawn gone as soon as possible, herbicide is the quickest way to kill it. Spray a product like glyphosate on the lawn while carefully following the package instructions. It might take up to two weeks for the lawn to completely die.
Glyphosate is a serious product, so take precautions. The Environmental Protection Agency has called it safe to use in residential areas only when used as indicated on the label instructions.
Another option for getting rid of your grassy (or annoyingly weedy and patchy) lawn is to grab a shovel and dig it out. Once you’ve pulled out the grass and weeds, solarize the area. Smooth out the surface, dampen it, and then cover it in clear plastic sheets for four to six weeks. Do this in the warm summer months to warm the soil.
For a larger area, you’ll want to use a rototiller to remove the grass and weeds. A rototiller turns the soil over, giving you a fresh surface to work with. Once you’ve pulled up grass and weeds, rake up the debris and put it in yard waste. Then till it again, switching the direction.
Tilling also preps the land for a new purpose, like installing a garden.
If you killed your problem grass in order to start on a fresh lawn, wait until the lawn is completely dead then rake up the debris. Aerate the area if the soil is compact, and then lay a fresh layer of sod with compost to give the grass seed some nutrition.
If you had a problem with your grass before, talk to the pros at your local lawn care company, hardware store, or nursery about your needs. They can help you find a grass seed blend that works with your soil, sun exposure, and foot traffic patterns.
