Easy Solutions First
If you don’t want to buy a product and would rather try your luck at home, there are a few things you can do. To find out what will kill clovers, but not grass, try these home remedies. Keep in mind, however, that products designed specifically for this will work better than anything you can cook up at home.
Use Your Hands!
Yes, the time-honored tradition of weeding by hand is still effective. Granted, it’s a bit of a pain on the back and knees, but you can certainly pull clovers manually.
You’ll just need a trowel or gardening knife and some gloves (though those are optional for the dirt lovers out there). Simply dig up the roots and then pull!
Deprive Clovers of Oxygen, Nitrogen, and Sunlight
Clovers thrive when given ample access to light, oxygen, and low-nitrogen soil. This is because they can produce their own nitrogen. To take this advantage from them, use nitrogen-rich soil when planting your lawn.
Additionally, you can use a plastic sheet or bag to prevent sunlight and oxygen from reaching the clovers. Keep in mind, however, that this may harm grass that’s nearby – so only do this with large patches of clovers.
Homemade Weed Killer
A mixture of white vinegar with a few drops of Dawn (or another dish soap) can be sprayed onto problem areas to kill clovers. Again, only do this on large clumps, and only spray it on the clovers.
Corn gluten can also inhibit growth without damaging other plants. It’ll dry out clover seeds to prevent them from being able to grow. Generally, 20 pounds of gluten is needed for every 1,000 square feet of lawn. Just water it as you would normally and allow it to dry after a few days.
Mow Your Lawn!
This goes in tandem with the method of removing sunlight. While not everyone is a fan of the long grass look, it can help kill unwanted wees. Simply mow your lawn at ~3-4 inches minimum height and the grass itself can help kill clovers.
This is because clovers are small and have a shallow root system. Allowing grass to literally dwarf it can allow your lawn to take nutrients from the clovers. This will actively make your lawn healthier, and clovers will die off.
This is a simple idea – clovers thrive in overly wet soil. So simply don’t overwater. Not only will this save you and be environmentally friendlier, but it will kill off unwanted weeds.
If, however, you’re in a naturally wet environment, this simply won’t work for you. If it rains commonly, move down the list. If not, try to water only once or twice a week, rather than every other day.
