Another challenging weed is Oriental bittersweet (Celastrus orbiculatus). You can try to eliminate it by putting in a lot of effort to pull and cut it, or you can moderate its growth with another method. To cut off its supply of nutrients and to keep the weed from smothering trees it grows around, simply cut the thickest vines from ground level to your waist. The method won’t kill the bittersweet weed, but it will slow it down enough to save your trees.
Instead, you can use a non-selective herbicide, such as vinegar, but the downside is that it will leave dead spots all over your lawn where the grass around the dandelion is also killed. The very best approach to permanently killing these weeds and sparing the grass is a two-step approach:
This is one weed that needs to be removed using a glyphosate-based herbicide . However, if you’re willing to put in the extra work, you can eventually beat Japanese knotweed by smothering it with tarps by cutting off the sun and water it needs to grow.
It will be easier to remove any type of weed at the root if you first wet the soil.

You’ll need a different method to kill an annual weed, such as crabgrass (Digitaria). Crabgrass starts its invasion anew each year. You could, theoretically, eradicate crabgrass in the spring by using a pre-emergent herbicide, assuming you get the timing correct. But, if you fail to eradicate this weed in the spring, you’ll have to wait and use post-emergent crabgrass killers on it in summer.
Here are the best ways to kill or at least slow the growth of seven common weeds, along with tips on what to avoid when trying to gain control of your yard.
Toxin-free corn gluten meal may be an antidote for crabgrass (and possibly dandelions). It also works as a good lawn fertilizer while also acting like a herbicide that prevents weeds from sprouting.
You may appreciate certain weeds, such as moss and wild violets. Some gardeners even cultivate moss plants as an alternative to grass lawns and consider wild violets as wildflowers.
Poison ivy (Toxicodendron radicans) is another cunning weed that most homeowners will agree that a property is better off without. Proper identification of the poison ivy in your yard should precede any efforts to eradicate it. You must be careful when removing poison ivy.
Taming a lawn full of weeds might feel daunting, but it’s all about keeping your turf as healthy as can be.
My lawn is all weeds. What should I do?
All year long, we look forward to sinking our feet into lush, radiant green grass. But nobody wants stringy ivy, coarse clovers or fuzzy dandelions grazing your toes instead!
What’s the best way to get rid of weeds permanently?
If you spray that, you can kill 80 to 100 percent of weeds’ top growth, found USDA research.
