Many of our clients ask us if they should plant grass seed or kill the weeds first. The answer is that the weeds should be killed first. Before any grass seeds can grow, the weeds and poor looking grass around the lawn should be killed. If you have a large lawn, you may want to consider using a lawn mower to cut down on weeds.

However, if your lawn is small and you don’t have the time to mow it every day, it may be a good idea to use a weed killer such as Roundup® Weed Killer. This herbicide will kill most weeds, but it will not kill all of them. If you are concerned about the safety of Roundup®, you can purchase it at your local garden center or online at

How do you kill weeds then plant grass?

Clear the area. Kill weeds and any remaining poor-looking grass with a non-selective herbicide about 2 weeks before you want to seed your lawn. The area should be raked to remove the dead grass and weeds.

If you have a large area of lawn, you may have to do this more than once. If you don’t have the time or money to weed every inch of the lawn every year, it may be worth it to just do it once or twice a year.

Will grass seed choke out weeds?

Abundant, vigorous grass overpowers weeds and denies them the nutrients they need to grow. Proper watering will choke out existing weeds and prevent weeds from growing in the first place. If you’re looking for a way to keep weeds out of your garden, you can use a variety of herbicides to control them. Some of the most common are glyphosate, dicamba, and 2,4-D.

These chemicals work by breaking down the plant’s cell walls, making it easier for it to absorb water and nutrients from the soil. However, they can also be toxic to other plants and animals, so it’s best to use them only as a last resort.

How do you grow grass where weeds are?

The key is opening the canopy of your lawn to allow seed to reach the soil and then seed heavily. After seeding, cut back any new weed growth which will help the seeds to grow.

Should I fertilize or kill weeds first?

You will want to get rid of them before adding fertilizers to your yard. Fertiliser products can be very harsh on your grass. Adding a product that can cause additional problems for your lawn is something you don’t want to do when weeds are already stressing out the lawn.

Can you put topsoil over weeds?

Some gardeners prefer to use foreign or imported topsoil as a means of discouraging weed growth. To use this method, first mow your lawn, then apply a 1-inch layer of foreign topsoil to the heavily weedy areas. Adding landscaping fabric is a precautionary measure against weeds that you can add to the mix.

If you have a lot of weeds in your yard, you may want to consider the use of herbicides to control them. If you are concerned about weeds, consider using a weed-killing herbicide such as Roundup or 2,4-D.

Is Pulling weeds a waste of time?

By pulling weeds when they’re small, they’re not only simpler to remove, but they also don’t get a chance to bloom and go to seed, which significantly increases weed problems. Being conscientious in early weed removal reduces the need to use chemicals that are harmful to the environment.
