How to Remove Grass in a Vegetable Garden?

Gardening is an excellent way of utilizing one’s free time; it is an incredible activity that rejuvenates a person’s mind, body, and spirit. The sight of blooming flowers and growing fruits and vegetables can make a person’s heart leap up with joy. Let us check out how to Remove Grass in a Vegetable Garden?


However, a thriving garden can be ruined when grass, the small green nuisance, peeks and spreads all over it. Grass restricts the growth of other plants and steals the nutrients from the vegetables being grown. Are you facing problems getting rid of unwelcome grass patches from your vegetable garden? Do you feel your vegetables are suffering while competing against grass and weeds in their supposed homes?

One of the biggest frustrations you’ll face while gardening is grass invading and taking over with its rapid growth. You would have tilled every grass patch under in your new garden and planted on top of it, and still, the grass comes back with a vengeance. Saving your garden requires a lot of work, but it is not impossible.

Grass has hollow, segmented stems. Varieties of grass include Bamboo, which can grow several inches a day in the right conditions, and Bermuda, which is usually the offender in our vegetable gardens.  Getting the grass growth under control in a garden is hard.

Any way you go about it is labor-intensive and difficult. However, once your patch is truly grass-free, you will have a much easier time keeping grass and weeds from coming back and smothering your vegetable plants.

However, you need to understand that if you do not remove these grass patches, they will suffocate your vegetables, make your garden look hideous, and compete against your vegetables for nutrients.

Weed is a broad term that can refer to any grass, flower, or even vegetable that is unwanted in your garden growing alongside your plants and vegetables. Vegetables need nutrients, water, and ample space to grow and blossom, and so do these weeds. They hijack all the crucial nutrients and leave your crops wilted and with no yield.

Some of the most common aggressive grasses that attack vegetable gardens include native grasses and yard grasses, broadleaves, legumes, invasive clovers, and forbs. These weeds spread through wind, water, animals, and fertilizer.

Let’s learn some tips and techniques for removing grass from your vegetable garden successfully:

Manual Labor

This method requires you to uproot grass in your vegetable garden manually. If you consider your garden as your baby, treat it as such and put some work into its healthy upbringing. This task is labor-intensive, so you’ll be putting in a lot of effort and giving a lot of time to it.

However, manually pulling grass out remains one of the simplest means of removing grass from a vegetable garden. Pulling up every piece, roots and all, is almost impossible to achieve.  However, the process is simple and effective when you pull up all the grass.


Digging the vegetable garden soil is the firmest way of removing grass along with destructive insects. It provides immediate results without the use of any substances and is best for a new garden. You can get different soil digging tools, such as spade and fork.

Direct use of these tools for sod removal may need a lot of time. You may get tired soon or get sore muscles; therefore, we recommend that you hire some helpers or ask some friends or family members to help you.

Spray water in the area a few days before you start digging the soil. It will make the ground soft and lose, making your search for grass easy. Make sure that the soil is moisturized but not soggy. Saturated soil is harder to dig as it is more substantial. Soggy soil can also restrict the natural growth of vegetables.

Now, take an edger or sharp spade to cut the sod into one to two feet wide parallel strips. This size depends on the density of turfgrass and the thickness of strips. Then, pry up a sod piece from one end and use the space to slide under it. Don’t forget to cut the taproots and other grassy fibrous roots. For loose soil under the sod, use a fork. Then, roll the strips up and keep peeling from their back.

To do a better bed installation and sod removal, you can use a sod cutter with a steel blade. After clearing the side, check if there is any pest or larvae present. Remove them if you find them.

Sod removal through digging is an excellent method. However, it has a negative impact too. During sod removal, organic materials are also disposed of. These natural materials are suitable for growing healthy and sustainable plants. However, you can use them for preparing compost and fertilizer.

Organic Herbicide

If you do not want to spend hours with your back bent picking out grass from your vegetable garden, you may consider applying organic weed killers on the weeds in your vegetable garden.

Organic weed killers or herbicides, like Avenger Weed Killer, help remove unwanted vegetation like grass and weeds in vegetable gardens. When applied to the targeted patches, the organic herbicide gets rid of established weeds and grass patches.

Avenger Weed Killer is organic and made of natural materials such as oranges and lemons. It is used in a 3:1 dilution concentrate; this quantity has a destabilizing effect on grass growth.

Another herbicide that could be used is glyphosate. Glyphosate is effective against grass and weeds, but it can also destroy vegetables and plants. Therefore, you have to be cautious while applying it in your garden. You should only target the grass and nothing else. Taking this precaution makes the process labor-intensive as well.

Apply glyphosate in your vegetable garden when the soil’s temperature goes down to at least 60 to 65 degrees. Spray the grass with the herbicide and allow it to seep into the grassroots. The herbicide works by getting absorbed by the grass into its roots. When the roots absorb the poisonous herbicide, it will become stunted and stop growing.


Lawn gardening tools are useful for planting vegetables, and the rototiller is one such tool. It can clean all the old weeds and grass. The tilling method helps to retain the original organic matter. You can fertilize the soils besides tilling the beds.

Firstly, you should clean up the yard before tilling. Remove all the sticks, rocks, particles, and other garbage from the garden. You can rake the area to do so. After that, you can deal with the old sods. Take a sod cutter to eliminate grass from their roots.

First, you should wet the soil with water. Let the water soak at least two inches deep. But you have to be careful that you are not making the soil muddy. You can start tilling the damp soil if it isn’t being held in a clump. Let’s catch up on the rototiller and finalize the task.

You should set the depth bar between 4 and 6 inches on the rototiller. Keep the cover down if the device has any door or guard. The next step is to use mulched compost or fertilizer on the soil. After that, rake the whole area and level the top portion of the ground.

Assume that you are mowing the garden. So, look for any existing grass in the yard. It would help if you didn’t leave gaps between the rows. For an improved result, you can till the soil again from another direction. For example, first till from North to South and then from East to West. Always rake the ground to level the surface. Once you are done, your garden is ready for planting vegetables.

Tilling a garden offers immediate plantation of vegetables. However, it becomes problematic when the soil is rocky and drier.

Use Vinegar

It may sound odd, but vinegar is quite useful for removing grass in your vegetable garden. However, its drawback is that, besides unwelcome grass patches and weeds, it also kills the plants you’re growing. Vinegar is potent against plants due to its acetic acid content, which drastically lowers their pH.

To prevent the vinegar from harming other useful vegetable plants in the garden, you must apply it to the target grass and weeds cautiously.

Being cautious when using vinegar may mean more work, but it would be worth saving your useful plants and getting rid of threats from your garden.

When using vinegar to remove grass in a vegetable garden, dilute it. You can create a diluted vinegar solution by mixing 4 ounces of lemon juice with 1 quart of apple cider vinegar in a bowl. Stir the mixture thoroughly and pour it into a spray bottle.

Choose a warm day, preferably in the afternoon or when the temperature is the highest; spray a generous amount of the mixture onto the weeds until they have absorbed it. The combination in the vinegar solution will attack and kill the roots and leaves of young weeds.

You will have to apply the vinegar solution multiple times on older weeds before they eventually give in and stop growing.

Suffocation of Grass

Suffocating or smothering the grass is perhaps the least stressful technique. You would hardly find such ease in getting rid of weeds and grass. Simply use layers of newspaper, plastic, cardboard, etc. to complete this task. This process stops the grass’s photosynthesis, which is vital to stunt the growth and prevent it from competing with your crops.

Bring a thin plastic paper according to the size of the vegetable lawn. You can choose polythene paper available in the market. However, it would be best if you made sure no air or sunlight passes through the paper.

Spread the plastic over the lawn garden where the grass is creating issues. Be careful about covering each edge. Leaving any grass open or uncovered can lead to failure, wasting all your efforts. Hence, cover the place adequately so that sunlight and air are not accessible through the layer.

This way, grass can’t grow since there is no sunlight or other essential nutrients. As you cover each edge, the internal temperature beneath the plastic paper will rapidly increase and become unbearably warm. The grass will then become dry from its stems and wilt off. The plastic cover works more significantly than the newspaper or cardboard. However, it’s not biodegradable. It can potentially kill organic materials of the soil too.

You can use old papers, newspapers, and cardboard instead of plastic. After spreading these on the garden, cover your essential organic materials with leaf mold, mulch, or grass clippings. This procedure will kill the grass but protect your necessary resources.

Gardening experts suggest using newspapers which are printed with only black and white inks. The colored printed paper contains heavy metals and coloring, which can harm your vegetables’ growth.

Suffocation or smothering is useful unless you want to plant your vegetables immediately. If you wish to prepare your soil quickly, choose a newspaper or cardboard. Plastic smothering will delay planting up to several months.

Boiling Water

This method works when the garden is not significant in size. All you need to do is pour hot boiling water over the grass patches and watch them gradually perish.

The hot water kills the grass by turning it brown and eventually killing all the nutrients that allow it to grow. Remember that you would have to carry out this procedure repeatedly because, after the first application, the roots or some of the sources remain viable.

So, to ensure that the grass is dead down to its roots, you should pour as much hot water as you can over them every few days until you see no more vegetation.


Mulching is an organic technique used for removing and preventing the growth of grass in a vegetable garden. A four-inch layer of the mulching matter is required to discourage the growth of grass and weeds in your garden.

Mulch works by blocking sunlight from reaching the grass and their seeds underneath so they cannot germinate. When spreading the mulch material, keep them at about 3 inches away from the plant stems. Remember that mulch affects the soil’s temperature. Hence, it could lower or enhance the temperature depending on the season and the materials used.

Inorganic mulch materials like plastics can improve the soil’s temperature, favoring the optimal growth of newly transplanted seedlings and germinating seeds.

Meanwhile, organic mulch materials, such as shredded woods, mature compost, and straw, lower the soil temperature and are favorable to vegetable plants during summer. Even though organic, sawdust is a soft material for mulch because bacteria that breaks it down starves the soil and surrounding plants from accessing nutrients such as nitrogen.
