How to kill grass

How to kill grass

Grass can cause a lot of problems in your garden if it starts to grow as a weed. A neat and perfect garden will be threatened if the grass grows uncontrollably. Thankfully, there are effective solutions to kill natural grass lawn. 

5 reasons to kill your grass  

1. Your grass is very messy

Grass spreads underground, and if it doesn't stay in place because you don’t use garden edging, it can reach areas where you don't want it to be. In this case, it is necessary to kill the grass so that it does not continue to expand.

2. You don't have enough time to dedicate to maintenance

Having a garden with natural grass requires time and effort. It is necessary to do regular maintenance (cutting, removing, fertilizing, aerating and watering) which is why many owners prefer to hire companies that specialize in lawn maintenance. If you don't have enough time to maintain your lawn, it may be a good idea to remove it entirely and put artificial grass in its place.

3. You want to save water

All garden owners know that it is necessary to use a lot of water to water the lawn. If you want to save money and not invest so much money to irrigate your lawn, removing the grass will be a convenient option.

4. You want to start or expand your garden

Having your own food garden is a great way to connect with nature, learn from it and know where the food you are consuming comes from. If you want to start a garden or expand the one you have, you will probably need a lot of space. For this reason, removing natural grass from your garden could be a solution to start growing food in your own home.

5. You want to start from scratch

If your grass no longer looks healthy because it is full of brown spots, pests, or weeds, it may be a good idea to start over. To do this, you will have to kill and remove all the grass and start from scratch.

What are the best ways to kill grass and weeds?

There are many ways to kill weed roots. Below we share the most effective ways to kill grass and weeds. 

Taking it off with your hands

The grass has deep roots and one way to kill it is by extracting it with your hands. This may take time and a lot of effort, and will only be effective if there is little grass to remove. It is important that you do this action in depth and from the grassroots because if you leave  some loose roots, they can easily sprout again. Once you finish, you can plant another type of grass.

Boiling water bath

Boiling water is very effective in killing all types of plants. You just have to put enough water in a pot, boil it and then water it on the grass you want to kill. It is important that it penetrates the soil so that it can access the roots. If you want to plant new seeds, you need to make sure to clean up all the debris.

Thermal herbicides

There are weeding techniques to remove grass that work by taking advantage of the heat. It helps to prepare the soil for subsequent cultivation and also serves to eliminate gravel or stony grass by means of a thermal shock that prevents their growth. This technique can also be used to remove weeds from the edges of flower beds, as well as along paths or between pavement joints.

Electric herbicides

These grass killer herbicides have certain things in common with thermals. They do not need to use gas cylinders but instead provide the aid of a real, electric, and useful torch for the removal of the grass. The grass is completely burned and the heat of the flame reaches very easily even the deepest soil. 

This stunts the roots of the weeds, which prevents their growth as well as new germination.  Thermal and electric herbicides have the advantage of not requiring the intervention of potentially harmful chemical agents. They are very easy to use and adapt to all kinds of needs and budgets.

Natural herbicides

These natural herbicides can kill grass fast. As they can be done comfortably at home, they make it easy to achieve optimal results as in the previous two cases, but also have the advantage of not eradicating potentially useful insects, especially in organic crops. There are several ways and methods to make these natural herbicides and kill weeds permanently.

The most used by farmers is a mixture that is made of vinegar and lemon juice, in the proportion of 1 liter of white vinegar / 120 ml of squeezed lemon juice that should be sprinkled on the grass until it dries.

Cover with newspaper

Newspaper is very useful to block the sun and prevent the grass from growing and developing. To kill the grass using this method, all you have to do is spread newspaper over  the grass and then cover everything with soil. This will ensure that what is under the paper does not continue to grow. 


Salt is a herbicide and natural weed killer, just like vinegar. When you spray it on the ground, it stops grass and weeds from growing. This is an affordable and effective solution, and you can add more salt every few days. This mixture can be made with dish soap and boiling water, and then applied with a spray bottle.

Fire weeding

Fire weeding consists of disinfecting the soil with a flame. This should be done before sowing seeds to avoid weeds. The high temperatures completely eliminate the grass seeds or weeds that are already present in the soil.

Prevent grass from blooming

If you have noticed that there is unwanted grass in places where you did not expect it to appear, it is important to make sure that the grass does not reach its flowering stage because it produces seeds, it is more difficult to eradicate. Indeed, even if you remove the grass from the roots, its seeds are capable of surviving a couple of years. 


Compost is an essential element in all gardens. It is basically a protection of organic matter, which must be applied to the surface of the land to guarantee a series of benefits:

  • Keeps the soil moist and cool?
  • Prevents the light that weeds use to grow?
  • Improves the quality and fertility of the soil?
  • Reduces weed growth?
