Things to consider when buying a weed killer:

If you’ve sown a meadow, you know that sooner or later, you have to fight weeds. These are divided into two types of weeds: broadleaf and narrowleaf weeds.

The term broadleaf refers to weeds that belong to the botanical class of dicotyledons. Narrowleaf on the other hand, fall into several species and are generally monocotyledons that are part of the grasses. In this category, for example, Digitaria, Setaria, and Gramineae should be included.

If the weeds are present on the lawn for more than 10 specimens per square meter, it is time to apply a chemical weed killer, or apply natural herbicides.

It is vital to identify the weeds on your lawn that you need to deal with as choosing the herbicide that is right for your occasion will get you the best results. In the case of lawn, it is essential to keep a product that won’t kill your grass, but instead work selectively.

Many people will have pets or kids that have access to the lawn, so it is wise to take that into consideration if you plan to use chemical solutions. Some on them can be quite harmful so try to restrict their access or go for natural solutions so you will have one thing less to worry about.

Chemical killer for lawns

Chemical herbicides are products with more or less high toxicity depending on the molecules they are composed of. Therefore, they should only be managed and used by capable people. Or get advice from an experienced person.Chemicals act selectively on certain species of plants. This is the easiest way to solve the problem, but also the least ecological.

Products should be purchased based on the type of weed to be eliminated. Carefully follow the instructions for use and under appropriate climatic conditions. How to have a minimum temperature above 12 Celsius and never with rain, even expected within two days.

As I told you before, these killers can eliminate specific weeds, fully preserving the good species that make up the lawn. Total herbicides instead eliminate any plant species, useful or harmful.

Selective herbicide should, therefore, be used on lawns, which are composed differently depending on whether narrowleaf or broadleaf weeds are to be eliminated. There is no weed killer active against these two groups at the same time.

Some herbicides act as pre-emergent. They hit the seeds of the weeds present in the first centimeters of the soil, and in the germination phase. Other weed killers are active as post-emergent, on the now well visible vegetation of weeds.

The first are more suitable for narrowleaf weeds, the second for broadleaf plants.

The effect of the herbicide on weed leaves begins to be noticed about 4-5 days after the treatment. It is made evident by a fold, followed by a reddening of the leaves, remaining instead entirely green and intact the surrounding grass.

Afterward, the plant dries out and is easily removed with a cut or a rake.

Natural killer for lawns

The natural herbicide has the advantage of being economical and ecological. A disadvantage? It is not selective and risks ruining even good grass.

For herbicide applications, you can also use a knapsack pump with fan-shaped nozzles for faster and more even spread. The effect of the product will be visible in the following days. When you notice that weeds gradually dry out and die.

The ingredients you need to make the natural herbicide are:

  • 5 liters of water
  • about 1 kg of salt
  • 1 liter and a half of vinegar

Once you have prepared the ingredients, you have to dissolve the salt in 5 liters of hot water, stirring well until it melts. After doing this, add the vinegar and mix everything together.

Here’s your natural killer for lawns DIY. It is an entirely natural product that is effective, economical, and environmentally friendly. Useful advice. It’s preferable not to use the product if rain is expected in the next two days, as it would not let the treatment work. For the same reason, you should avoid watering the lawn for a couple of days.
