Step to Follow on How to Stop Grass From Growing Under Fence

Step One: Determine

The first thing you need to do is determine whether or not it’s worth investing some time and money into killing those pesky lawn weeds. If this is a new-ish problem, then you might want to wait a season before trying any of these methods, as the grass may just be coming up from deep rhizome root systems.

However, if you’ve been trying for a while with no luck, then it’s probably time to invest in some weed killers. At the very least, consider applying one of these methods before spending money on chemicals that only kill the top part of the weed and may not stop any new shoots from growing back up.

If your lawn is in a high-traffic area and you want it to look nice, the best method will be to pull out the weeds by hand. Otherwise, you can rely on one of these other methods if stay-ability isn’t essential. For example, I don’t mind the grassy areas outside my front door because they’re right at the edge of the property, and I won’t be landscaping around them anytime soon.

Step Two: Mark the Areas

Before you pull the weeds, mark off the areas with some spray paint so you aren’t tempted to pull any of them when you’re in there planting new shrubs or flowers in the future. The weed killer method really won’t be effective until after a few weeks have passed, but during that time, it’s easy to accidentally take out some of the flowers you’ve already planted.

If you’re not planting new plants in that area, then you’ll need to cover the surface of the ground with some tarps or sheets of plastic before applying any weed killer. The most important thing with this method is that absolutely nothing gets on your lawn grass.

Planting New Plants

If you don’t want to buy tarp or plastic, you can lay down some leftover carpeting as this guy did. His lawn was about four feet wide, and he laid two by fours on its surface before covering that with rolls of carpet. While the carpet wasn’t necessarily pretty, it was effective enough for him to kill weeds without killing grass.

Step Three: Lay the Tarps Aside

After a couple of weeks, remove the tarps and dump them in the trash. The main reason for this is that grass will start to grow through any small holes, and you don’t want it to do so over your weed-killing plastic sheets because you’ll be effectively growing grass directly on top of your weed-killing plastic sheets.

The other reason is that you have to put the tarps into the trash because they are covered in toxic chemicals. You won’t want to dump them on any other grassy areas, so take them down to the local landfill and get rid of them there.

You can use black plastic sheeting instead of buying tarps if you want to save money, but make sure that your plastic is at least six millimeters thick, though you can go up to 10 millimeters if you want. These steps should help you in learning how to stop grass from growing under fence.

Step Four: Apply the Grass Killer

Anything that kills lawn grass will kill the weed grass as well. If you are using a weed killer, read the label’s directions to determine how much to apply. If you are using Roundup, only use it outside in the open air where there isn’t any risk of troubling vegetation growing near your home or along your property line.

If this is an older method requiring soap, salt, or household chemicals, you also need to be very careful with how much you use. Too much soap or salt can weaken the soil near your home or make it more likely for grass around your lawn to die.

If you are using vinegar, avoid applying directly on top of sidewalks and patios as this is hard on the cement. Also, make sure that the vinegar is of decent quality, as anything that smells or tastes sour probably isn’t going to do an excellent job of killing the weeds under your lawn.

Step Five: Maintain the Kill

If you don’t want the weeds to come back, you need to water your lawn regularly. This is especially true during an ongoing drought like the one that California is currently experiencing. Do not skip watering even if no new shoots are growing up through your weed-killer sheets.

Watering Lawn Regularly

If they aren’t watered for two weeks or more, the weed-killer sheets will become ineffective because they will dry out. You’ll need to lay down new ones if that happens, so keep your lawn well-watered to ensure that it continues to be non-weed grass instead of just dead grass.
