Grass killed by Roundup does not grow back from the root. Roundup is a very effective chemical herbicide that completely destroys all kinds of plants. If a herbaceous plant turns brown 14 days after being sprayed with Roundup, it will not come back.

  • Roundup completely kills the grass, stopping regrowth from the roots;

Standard Roundup does not act as a pre-emergence herbicide, so it does not kill weeds or grass seeds in the soil. The area where the grass killed with the Roundup is inclined to re-attack, so it’s time to plant a new lawn or take additional weed control measures.

Wait 2 weeks before removing grass

Roundup is an effective post-emergence herbicide that kills grass and weed right down to the root with very little chance of error. However, this process takes time.

Rushing can result in only partial removal of dead grass and plant debris, or disruption of the process resulting in only the top layer of weed or grass dying off.

Gather dead grass after harvest with a sod cutter

If you want to remove dead grass from a large area, a new sod cutter may be the most effective way to remove large amounts of dead grass; roots and all. In many cases, renting a sod cutter is the most economical way to purchase this tool, as it is hardly ever used other than to remove large areas of the divot and dead grass.

Most hardware stores will rent them out to you, or you can hire a local lawn and garden company to remove lawns.

The new sod cutter will cut dead grass and sod at any depth you set. Usually, it is 2 to 3 inches. Sod cutters, while easier to use than a shovel, can still be very difficult to maneuver and lift.

It can be helpful to have another person around to help you make the most of your rental time. Although the sod cutter will cut the sod off the soil, it is important to note that the new sod and grass will then need to be rolled up and hauled out by hand.

Grass clippings

As an alternative to using a lawn mower, you can remove dead grass from your entire lawn with a normal power rake and lawn mower. To do this, observe these actions:

  • Place the mower cutter to its lower set to mow grass close to ground level;
  • Grass clippings in your garden carefully, collecting the mow grass in a bag;
  • Use a puller or electric rake to remove any remaining straw and root material;
  • Mow and repack to remove thatch;
  • Rake up the remaining straw and dump it.

This process is frequently quicker than utilizing a divot knife, and it doesn’t pull special topsoil from your yard. If you intend on reseeding your lawn within the following occasional months, this is the finest method to remove dead grass from your entire lawn yard.

Collect dead grass after Roundup by tilling the soil

It’s not so much a method of removing dead grass after Roundup, but a way to make the most of it. All you need is a tiller. Larger and heavier models are best suited for this task.

While a lighter model can be used, you will need to make many more passes, while with the type of cultivator you can rent from most farm or hardware stores, you can do it in one pass and only need to clear the yard to even it out.

Whatever type of cultivator you choose, be sure to set it to a depth of about 6 inches. This makes sure that grass and weed are drawn deep into the soil and do not become a problem for new shoot roots or new grass seed placement.

Collect dead grass after the Roundup by digging and raking

The next option, and perhaps the most thorough option after using the sod cutter, is the more “traditional” method of digging and raking.

For this to work, it can be helpful to cut the lawn as short as possible and collect or rake the cut grass first. If you have a straw removal tool, run it over your lawn, and it will be easier for you to dig into the ground with a shovel.

Once you start digging, you have two options for what to do with the sod. First, you can try to stick the shovel just a few inches underground and cut the grass at the already dead roots. This sod can then be composted or discarded.

Alternatively, many people choose to dig 4-6 inches and then turn the sod over. Dead grass will decompose and, over time, will nourish your new lawn or any plants added to the area. Once everything is dug up, rake the area to smooth it out and pick up any small remaining clumps of dead grass.

Collect dead grass after harvest by trimming

This method is only applicable if you are trying to kill grass between rocks or other types of cracks and crevices. Roundup kills grass and any other plant on the vine. This means that even if you do not remove the entire plant, it will not continue to grow. Any weed growing between the rocks can be cut at ground level and will collapse over time.

This is also true if you plan on placing rocks or other materials on top of freshly cut grass. All you need to do is cut the grass as low as possible first.

However, it may also be helpful to sprinkle the area with a germination inhibitor such as seed gluten meal to prevent weed or grass seeds from growing. This seed may have been blown by the wind from the Roundup spray and therefore not affected by the glyphosate.

What can I use to remove dead grass?

It is important not to remove all of the grass, but just break up the top layer of thatch. Remove the loose dead thatch either with shovels, by hand, or with a string trimmer. Do not leave any clumps on the lawn. Re-seed the barren patch of lawn and water if applicable.

Sod cutter

You can lease a sod cutter from your native hardware shop. These convenient motorized tools will remove living grass from your lawn along with a 2-3 inch top layer of soil where the grassroots are the widest.

When used correctly, the cultivator can recombine dead grass with the soil. This will loosen the soil, causing it a finer location for new grass or sod seeds to take root. It also includes dead grass with mud to run up decay. To complete this technique job, do the pursuing:

  • Mow dry grass at the lowest mower blade height. Pack the cut grass in a bag;
  • Use the cultivator to thoroughly plow up the dead grass to a deep of 6 inches.

For this purpose, you can rent a cultivator from a topical hardware shop. Digging up dead grass into the soil is quite useful in scheduling the soil for divot or seed placement. However, tillage can cause buried weed seeds to float to the surface, where they attempt to germinate. Drench the site for 2 weeks and destroy any germinating weeds or unwanted grasses.

Suitable for: Large areas where new seeds or sod will be planted.

String trimmer

Behind you’ve employed Roundup to kill grass sprouting between bricks or concrete joints, use the string trimmer to cut the dead grass at ground level. Since glyphosate, the active ingredient in Roundup, kills grass down to its roots, you won’t have to worry about growing again. Dead roots decay innately.

This technique can even exist employed on small patches of grass in the yard. A string trimmer positioned near to the ground will cut dead grass at ground level and break up the tough straws. We do not recommend employing a string trimmer if you are trying to remove dead weeds from stones.

Suitable for: Removing dead grass between pavers or in definite joints.


When removing dead grass in small areas of your yard, there is no requirement to lease heavy motorized equipment. To obtain rid of grass killed by the Roundup, you can use a shovel or a square shovel.

  • Use a shovel to cut the dead grass into approximately 8 square inches squares.
  • Remove 8-inch patches of dead grass along with 2-3 inches of topsoil;
  • Clearing the topsoil acquires rid of origins and thatch, preparing the ground for new sod or seeds.

This method essentially repeats the operation of a divot cutter on a smaller scale. To make your job easier, water the area the day before you plan to remove dead grass. This will make digging easier.

Suitable for: Preparing small areas where seeds or new turf will be planted next to existing grass.
