If you want to stop weeds from growing in your lawn, use a grass-safe herbicide to kill any weeds that are present. Then, spread a pre-emergent herbicide that will stop weeds from sprouting but won’t harm your grass. You can also use pre-emergent in your garden to stop weeds from growing. If you have weeds growing through gravel or in paved areas, use a powerful herbicide that kills existing weeds and remains in the soil to stop new weeds from sprouting.

What Stops Weeds From Growing?
Pre-emergent herbicide is a special type of weed killer that actually kills weed seeds as they begin to sprout underground. This prevents new weeds from cropping up wherever you’ve spread your pre-emergent. Because pre-emergent herbicide doesn’t kill actively growing grass or plants, it won’t destroy your lawn or garden. Just pull out the weeds that are currently there and spread pre-emergent. This will stop new weeds from growing.
- Spread this pre-emergent herbicide on lawns and gardens to prevent new weeds from growing.
- Use this powerful post-emergent herbicide to kill all plants growing in an area and prevent future weed growth.
If you aren’t concerned about saving grass or plants in a weedy area, you can permanently kill weeds with a powerful post-emergent herbicide. These sprays kill all the plants they touch. Plus, they linger in the soil to prevent new weeds from sprouting for up to 1 year.
Does Vinegar Kill Weeds Permanently?
Vinegar does not kill weeds permanently. If you treat weeds with a mixture including vinegar, you will only damage weeds for a short period of time. This is because the acetic acid in vinegar burns the leaves of weeds but is neutralized by the soil. This means that the roots of the weeds will be unharmed. The damage to the leaves of weeds may make you think you’ve done the job, but the weeds will regrow from the roots.
- Vinegar only damages the leaves and stems of leaves—it doesn’t kill the roots.
- A weed sprayed with a mixture including horticultural vinegar is extremely likely to grow back.
- Hand-pull weeds or use a strong herbicide to stop weed growth permanently.
If you want to kill weeds permanently, you need to pull them up by the roots or use a systemic herbicide. Removing a weed by the roots prevents it from growing back. Systemic herbicides work by infiltrating the plant and killing it to the root. Both these options are several times more effective than homemade weed killer made with white vinegar.
How to Permanently Stop Weeds from Growing in Grass
In order to stop weeds in your lawn permanently, you’ll need to use a combination of post-emergent herbicide and pre-emergent herbicide. Post-emergent herbicides kill weeds in your lawn without harming grass, while pre-emergent herbicide stops weeds from sprouting. These two products will combine to make your grass weed-free permanently.
Spray a Grass-Safe Herbicide to Kill Existing Weeds
There are several herbicides that are safe for use on grass. These herbicides will kill almost all types of weeds—including hardy perennial weeds and grassy weeds—without harming your lawn. While vinegar-based weed killers will damage grass and weeds at the same time, selective herbicides kill weeds but don’t harm grass.
- This weed killer will kill weeds in your lawn without harming your grass.
- A homemade weed killer with vinegar will harm weeds and grass equally.
- A weed killer meant for lawns should not be sprayed in your garden.
Although these weed killers are designed to ignore grass, they can’t differentiate between weeds and garden plants. A post-emergent herbicide should never be sprayed in your garden. It is likely to kill your desirable plants.
Use Pre-emergent to Stop New Weeds from Sprouting
If you want to stop weeds from growing in your lawn permanently, your best option is to begin spreading pre-emergent at the proper time in spring and fall. Pre-emergent herbicides enter the soil and remain there for weeks or months. During this time, any weed seeds that attempt to sprout will be killed before the sprout breaks the soil surface.
- Spread a pre-emergent herbicide in spring and fall to stop weeds from sprouting in your lawn.
- Because pre-emergent kills weed seeds as they sprout, you won’t see any new weeds.
- Pre-emergent won’t kill plants that have already sprouted, so your grass will not be harmed.
The best thing about pre-emergent herbicide is that it doesn’t harm any actively growing plants. Your lawn grass will be unaffected. Only new seeds that attempt to sprout will be killed. By spreading pre-emergent on your lawn twice per year, you’ll stop weeds from ever growing in your lawn.
How to Permanently Stop Weeds in Your Garden
You can use the same pre-emergent herbicide you spread in your lawn to stop pesky weeds from sprouting in your garden. Pre-emergent is especially effective against annual weeds. Annual weeds grow, drop their seeds, then die before sprouting from seeds again. If you use pre-emergent in your garden twice yearly, you’ll stop invasive weeds from sprouting among your vegetable plants and flowers.
- Pre-emergent herbicide will stop weeds from growing in your lawn and garden but won’t kill nearby plants.
- You can spread pre-emergent in your garden at the same time you spread it on your lawn.
- Pre-emergent will kill any seeds that sprout but won’t kill weeds that are already visible.
Although it’s an excellent idea to use pre-emergent in your garden since it will kill garden weed seeds as they sprout, there is one drawback. Pre-emergent won’t kill actively growing plants. This means it won’t harm your veggies, but it also won’t kill weeds that have already sprouted. You’ll have to pull mature weeds out of your flower beds. Then, use pre-emergent to permanently prevent weeds from returning.
How to Permanently Stop Weeds in Concrete Seams
If you are trying to kill unwanted grass or a troublesome growth of weeds between concrete pavers, bricks, or any other place where you don’t want any plants to grow, use a powerful weed killer. A strong systemic herbicide will kill all types of weeds down to the root. It is also formulated to remain in the soil for up to 12 months, stopping any new plants from sprouting.
- Use a long-lasting herbicide to kill weeds growing in areas where you want no plant growth.
- Long-lasting herbicides kill mature weeds and stop new weeds from sprouting.
- This type of weed killer is not safe for grass or garden plants.
This type of herbicide is a combination of post-emergent and pre-emergent. However, it is extremely powerful and will kill any plant it comes in contact with. Use it only in areas where you are certain you want no plants to grow for 12 months.
How Do You Permanently Get Rid of Weeds in a Gravel Driveway?
Natural weed killers that include vinegar won’t permanently kill weeds in gravel. Get rid of these unwanted plants with the same hybrid herbicide used for killing weeds growing through concrete. This type of effective weed killer will wipe out weeds in gravel and stop them from returning.
- Use a powerful weed killer to permanently wipe out weeds in gravel.
- Avoid using “natural methods” that include salt.
- Salt is easily washed into other areas of your lawn by rain, where it will wipe out grass and plants.
- Herbicides are designed to bond with soil so they aren’t carried away from where you sprayed them.
Don’t use a homemade weed killer with table salt on your gravel driveway. Unlike specially designed, long-lasting weed killers, salt is easily spread to other parts of your yard by water runoff. Wherever you spread salt, it can be washed into other areas. This will create dead zones in your lawn where no grass or plants will grow.
How Do You Permanently Stop Weeds from Growing?
In order to kill weeds down to the root and permanently stop them from returning, use the following methods:
- Lawn Weeds: Kill existing weeds with a grass-safe herbicide. Then, spread pre-emergent to stop new weeds from sprouting.
- Garden Weeds: Hand-pull weeds, then spread pre-emergent to prevent weed seeds from sprouting.
- Weeds in Concrete/Gravel: Spray a combination herbicide that kills weeds and prevents them from growing again for up to 1 year.
By following these rules, you’ll have a permanent solution for weed problems throughout your yard.
