Safest weed killers: Top 7 herbicides to use on your lawn

It is inevitable to use weed killers, especially when a few organic options fail to kill the weeds on your lawn. For most homeowners, the most practical solution, in this case, is to buy a commercial chemical spray and apply it to the unwanted plants.

But things can quickly go wrong, particularly when you fail to understand how the herbicide works or the ingredients used to make it.

That is why buying the safest weed killers should be your priority regardless of the type of weeds in your yard.

Going for the safest weed killers is crucial because a stronger concentration of chemicals in a product does not mean it will work better.

You may have to spray it several times since the plants will grow at some point, instead of going for a one-time application.

Furthermore, if you have children and pets, you should use pet-friendly herbicides on your lawn, preferably those that have all-natural, organic, or food-grade ingredients.

How do you use weed killer safely around children and pets?

When you are using a lawn care product around your children and pets, you need to exercise a little caution.

Pulling weeds

The first step starts by reading the label on the herbicide before opening its container. Know whether it is safe to use around kids or domestic animals.

Secondly, check to see if you need to dilute the weed killer to make it less toxic to humans and dogs or cats when they come into contact with it.

If you are using a chemical weed killer, do not dump any excess. Use the recommended amount for the size of your lawn.

Understand that many chemical herbicides provide a safe and effective solution for controlling unwanted plants in your yard. But that will depend on how you follow the instructions on the label.

Will granular or liquid weed killer work better?

When shopping for the safest weed killer, you will encounter either granular or liquid (spray) weed killers. Go for the spray option if you are dealing with overgrown, difficult-to-remove weeds.

Granular herbicides are better as a pre-emergent method of weed control. You can use them before the plants germinate to ensure they do not grow on your lawn.

But it is better to go for liquid weed killer instead of granular since the former will stick well on unwanted plants.

Factors to consider before purchasing the safest weed killers

When shopping for a non-toxic weed killer, pay attention to the following factors:

1. Type of Weeds

Weeds can either be broadleaf or grassy plants. Some herbicides have formulations for only killing one specific type and not the other.

Therefore, buy a product that can eradicate all weeds on your lawn.

2. Ingredients

The ingredients that make up the weed killer can tell you whether it is safe to use on your lawn or around kids and pets.

While you can buy those that contain glyphosate, they may not be safe depending on the concentration of the chemical. But consider a herbicide that has all-natural or organic components.

3. How long it takes to kill weeds

Some weed killers can eradicate unwanted plants within hours. Others can take weeks to work.

Make sure to choose those that offer results within the shortest time.

4. Application

You can either buy granular or liquid weed killers. The application will depend on how you want to eradicate the plants.

A spreader is the best for granular products, and a sprayer is ideal for liquid herbicides.

Conclusion

If you are looking for the safest weedkillers, consider products that have all-natural or organic ingredients. The ingredients to pay attention to are sodium chloride, vinegar, and soap, among others. Also, choose a herbicide that will eliminate common weeds such as dandelions, crabgrass, and oxalis, among other grassy weeds and broadleaf grasses.
