Grass herbicide

What is a herbicide?

A herbicide is a substance that is used to kill or destroy plants. They are classified into two main types:

  • Total herbicide:Are those that end up with any type of plant in the desired area.
  • Selective herbicide: They willonly eliminate weeds. For example, in the case of using a selective grass herbicide , the product will be responsible for eliminating weeds that may be present in the grass.

The truth is that this distinction will depend on the concentration of each product, or the dose to be used. For example, a herbicide for total grass can become selective if used in low concentrations. A selective one, on the other hand, can become a total if the dose is increased, ending any type of plant that is found along the way.

At the same time, herbicides can also be classified based on the form of action.

  • Contact herbicides:This product acts on the part of the plant in which it is applied, preventing the effect from moving along it.
  • Translocation herbicides:Also known as internally acting herbicides. Nothing more applied will be absorbed by the plant, acting from inside it and affecting different parts.

They can also be classified depending on the period of the harvest in which they will be applied. We have the pre-planting herbicides (those that will be applied while the ground is bare), the pre-emergence ones (those that will be applied before the stage of the cultivation stage), and the post-emergence ones (applied once the crops were born).

Grass selective herbicides

Depending on the result you want to get on the lawn, you will have to use one product or another. If our goal is to have a lawn that has spiny or grassy plants (that is, narrow-leaved plants), then we can opt for herbicides that affect plants that do not fall within this group.

It is quite common that in the grass there are some plant seeds that can invade it completely. Some examples of this are daisies, dandelion, clover. There are specific products to treat these problems; For example, a good herbicide for clover grass .

The problem with these broadleaf plants is that they can quickly invade the garden, affecting their aesthetics. These plants can improve the green tapestry of the garden, although it will depend on the aesthetics we want the lawn to have. If all we are looking for is to have a green mantle, using selective herbicides is a good solution.

These products can be combined with fertilizers to achieve good results. For example, a fertilizer with lawn herbicide can prevent clovers from appearing.

Keep in mind that grass is very demanding when it comes to demanding certain nutrients, such as nitrogen. At the moment when there is a lack of this element, the color will no longer be so green, we will even see that it will turn yellow. This will cause the clover to appear and spread, ending with grass grass. Therefore, to prevent the clover from spreading, it will be crucial to use a good selective herbicide, in addition to using specific fertilizers for grass, with a high nitrogen content.

Herbicide for artificial grass?

Yes, weeds can also be produced on artificial grass. Although it is true that removing this weed manually can be simple, it is not the best option. There are anti-moss and herbicide products that can be applied in these cases. Of course, they must have a water base to avoid affecting the structure of the material that shapes the artificial turf.

If we want to prevent weeds from growing on this type of grass, it will be crucial to eliminate any other organic matter that may be on the surface (such as waste or simply leaves). Not only must they be removed for purely aesthetic reasons, but also because they can affect the drainage system of artificial turf.

It is very easy to have: it will simply be necessary to carry out a gentle brushing against the hair (avoiding using metal brushes), or a leaf blower with a medium-low set power.

Homemade herbicides

Chemical herbicides usually have a composition that will not only be aggressive for the plants we seek to eliminate, but also for the environment. Therefore, it is not always the best solution. As an alternative, we can create homemade herbicides ; that is, to do ourselves at our own risk.

Important: A common mistake is to think that these herbicides, being homemade and natural, cannot cause damage other than the plant to be eliminated. But it is not so, and it can affect both the soil, the garden, or your health. After all, a herbicide really is a toxic substance for plants. If we apply the product in exaggerated quantities, or if the mixture is not adequate, it could cause problems in the ground or injuries to our person. The same care should be taken with homemade herbicides as with lifelong commercials.

If you want to make a herbicide for homemade grass , we indicate some of the best options:

Remedy with water (Dihydrogen monoxide)

This herbicide is recommended by experts, as it is quite simple to prepare. The only risk we can take is to spill boiling water on ourselves, but we would also run the same risk if we prepared, for example, macaroni.

All we have to do is prepare a pot with didrogen monoxodium (yes, it is simply water, but said professionally).

We boil it and wait. When ready, simply pour it on the stems and leaves we want to finish. It can be a good solution to end weeds on the road or sidewalk, or on a larger area.

Now, its action is total, not exclusive: that is, if you want to conserve some plants, the boiling water will also end them.

Sodium Chloride (Table Salt)

Common salt is the most common herbicide. Throughout history it has been used regularly; it was usual, once the conquered peoples were razed, to salt in the earth to prevent anything from growing there.

Sodium chloride has a detrimental effect on the soil substrate, so it is advisable to take special care with what we do. You just have to apply directly on weeds, and never soak the soil. Especially you must be careful with the plants you want to keep.

Our recommendation is that you dissolve 1 part of salt for every 8 parts in hot water. Also add a small amount of liquid soap (a component that will help the salt to set on the surface of the leaves) and distribute using a spray bottle.

Plants you don’t want to kill should be isolated; The best way to do it is by tying them.


White vinegar can usually be a herbicide for selective turf if applied accurately. What really kills plants is a component that has acetic acid in its formula The proportion of this component is usually 5%, more than enough to fulfill its task. We can buy vinegar that with a proportion of acetic acid that is above 20%. Being stronger is also more complicated to control: it could even affect our skin, eyes, lungs, etc.

Salt and vinegar

A combination of previous remedies. This homemade herbicide recipe will require that we make a mixture by combining table salt with white vinegar in a ratio of 1 cup of salt per 3L of vinegar). The resulting mixture must be applied as a spray. If we want it to be more effective, and persistent over time, we can always apply some liquid soap.


The borax is a product used for washing, being able to find from shops specializing in cleaning, and large and small establishments.

The proportion we are going to follow will be 280 grams of borax for every 2.5L of water. We will mix well and use a sprayer to cover weeds.


Some considerations before using lawn herbicides

Preventing and ending grass weeds is possible. With these products we have it very easy … but this does not mean that you don’t have to be careful, much less. Remember that the grass is a plant and that, as such, a series of care will have to be taken if we do not want it to be damaged or damaged in any way.

In the following lines we will see some tips to use the herbicide for grass .

  • Read the instructions:Before doing anything it is very important to read the product label and follow the instructions for use. Thanks to this we will be able to eliminate risks, and make the result more efficient. Keep in mind that skipping a single step can be lethal to the grass.
  • Suitable:Make sure that the herbicide for the lawn will not damage it; That is perfectly compatible.
  • Thought to kill concrete species:The herbicide must have been designed to kill concrete weed species . Well those that usually appear in the usual way by the area, by the weather, or by different conditions.
  • Application:The most advisable is to apply the herbicide on those days when the minimum wind is possible. Otherwise, it can easily expand through the air. This, in addition to being detrimental to our health, could also affect other plants, killing them.
  • Protection:Do not forget to protect yourself before using the herbicide. This type of product can be aggressive for the skin and nostrils, so you should wear protective elements such as a mask or gloves, long-sleeved shirt, long pants, high rubber boots. At the moment in which we have finished applying the product we will have to wash the clothes and prevent them from coming into contact with other garments or parts of our house.
  • Cleaning of tools:All the tools we have used will also have been impregnated with the herbicide, so they will have to be cleaned perfectly after each use. If not, as soon as we try another plant we will also be applying the product.
  • Discard the remains of weeds:The remains of weeds you have cut must be discarded before they reach other parts of the garden.
  • Adequate dose:Check that the dose you are going to apply is correct. If it is excessive we could kill the entire plant, but if it is inferior we will not notice any result.
  • Application:Being a toxic product, the herbicide for grass should not be applied when there are children in front, or pets.
  • Lawn mowing:It is absurd to mow the lawn once we have applied the product, since all we will do is waste time and money. Experts also do not recommend cutting it before. If the natural grass is freshly planted, it is recommended that we delay the use of the herbicide and ensure, as much as possible, that the mowing itself is responsible for controlling weeds
  • Maintenance:When you have finished using the herbicide you must ensure that you have closed it well and that you are going to store it in a safe area, away from the reach of children and pets.

We will achieve better results in the case that the herbicide for grass is applied on a young grass, in period of active growth. The reason for this is that it will not have matured enough to withstand the attack of the herbicide.
