What Is The Safest Weed Killer

Killing weeds takes a considerable amount of effort when pulling by hand; thus, many gardeners turn to weed killers to get rid of unwanted vegetation around the yard. However, many of these comprise harsh chemicals that are effective to get rid of unwanted weeds yet can contain harmful chemicals that are not safe for family and pets, especially young children.

In your hunt for a non-toxic weed killer, you can face many options, so which one do you choose to deal with invasive plants? You can consider an organic weed killer rather than hand pulling and using many gardening tools to avoid toxic chemicals.

Using a safe weed killer for lawns means using natural ingredients and an organic herbicide to kill many undesired weed species. So, how do you find the safest weed killer for use in your vegetable garden, flower bed, or lawn? (Learn What Is The Strongest Homemade Weed Killer)

In our guide, you can learn more about natural weed killers and which can be the best for use without harming other plants, your family, and pets.

Organic Weed Killer Guide

Best Organic Weed Killer Buying Guide

When looking for a safe and effective weed grass killer, avoid the first product that claims to be made with natural ingredients.

Examine the ingredients and study the labels to see if the product will only kill certain tough weeds or all vegetation.

Remember, there is a distinction between natural herbicides that kill existing weeds and those that prevent weed seeds from growing. You’ll also find some that you can use in vegetable gardens as they are safe to use around edible plants.

Pre-Emergent vs. Post-Emergent

The best organic weed killers are divided into two categories. Pre-emergent kills weeds that have been sprouted, and post-emergent kills weeds that have previously sprouted.

The difference is significant because once a pre-emergent is in the soil, it prevents any seeds from sprouting, including weed seeds and seeds from desirable plants and in your flower beds.

Selective vs. Nonselective

A selective weed killer will kill only certain types of weeds while leaving others alone.

Herbicides designed for lawns, for example, are likely to target broadleaf weeds like chickweed and clover, but the natural weed killers won’t harm turf grasses.

Gardeners should use nonselective chemical weed killers with caution because they will kill vegetation, including weeds and desirable plants.

In addition, spraying a nonselective weed killer across an entire yard to control weeds will kill both weeds and grass.

Users of natural herbicides have few options for selective solutions; the bulk is nonselective and designed to kill all types of weeds and grasses.

They can be used in cracks in sidewalks or pavers and kill all the weeds along fence lines.

Like many weed and grass killer, you shouldn’t use such products on windy days close to your desirable plants and flowers. (Find the Best Weed Killer With Pre-Emergent)


Some organic weed killers contain common household ingredients like vinegar and salt, which may surprise gardeners. In addition, soaps and essential oils like cinnamon and clove are also excellent ingredients.

Many organic weed killers contain lesser-known ingredients, including citric acid, caprylic acid (a coconut oil derivative), and D-limonene (produced from citrus fruits). To control specific pesky weeds, manufacturers may combine two or more of these ingredients.

Form of Weed Preventer

Natural weed-killing chemicals come in various forms, some of which are better suited to specific applications.

Sprays: Most sprays are designed for direct application to the weed’s foliage and provide uniform coverage. The spray is absorbed there and then goes into the plant, killing the weeds at the base.

Take the spray only to the weeds, and avoid doing so on windy days since over-spray may take the natural weed killer product to your desirable plants.

Liquid concentrate: A weed and grass killer concentrate may be the best solution for gardeners with extensive weed infestations or more significant areas to cover than smaller mulch beds.

Using a garden sprayer or similar, you can dilute the concentrated solution with water and readily apply it to unwanted plants over large areas.

Powder: This dry weed killer is typically used to kill weeds in specified areas without harming desirable turfgrasses.

Powder herbicides, like spray herbicides, may blow away from Southern lawns, and kill surrounding plants, so you need to apply them on a calm day.

Salts: Because salt-based products may kill healthy grass besides stopping new weeds from growing, you need to use caution.

It’s easy to contaminate areas of your garden using many weed killers of this variety. In most cases, salt-based weed killers are best used between patio pavers or sidewalk joints rather than in flower beds for weed control.

Organic and Natural Weed Killer

Organic Herbicides

There are more organic products on the market than ever, and the demand for organic alternatives to traditional weed control is growing.

Non-selective organic herbicides can contain clove oil, citric acid, or acetic acid (vinegar). Instead of harmful chemicals, these natural alternatives are nearly as effective as store-bought alternatives.

Although it is expensive and good for the soil, Corn gluten can be used as a pre-emergent herbicide to prevent spring crabgrass.

There are currently no alternatives to selective weedkillers like the broadleaf weed killer 2,4-D, which most weed-and-feed products contain. (Read Herbicide Safe For Clover)

Home Natural Weed Killer

Some weed-killing recipes have been passed down through generations, eliminating the need for store-bought chemicals. If you decide to make your own, pay close attention to the ingredients.

Common homebrew using vinegar (1 gallon), salt (1 cup), and soap (1 tablespoon).

The recipe can be altered, but the result is usually an excellent non-selective weed killer.

The vinegar’s acetic acid disrupts the plant’s cells, while the salt desiccates the tissue, and the soap helps the mixture attach to the plant.

More substantial vinegar concentrations (up to 20% acetic acid) boost its efficacy.

A moss killer made with Ultra Dawn dish soap and water is another common home cure.
Spray 4 oz. Ultra Dawn dish soap in 1 gallon of water over the moss, and it will turn brown and die in a week.

Creeping Charlie AKA creeping Jenny or ground ivy is a perennial weed that may take vast areas of a lawn.

Control creeping Charlie with water and regular household borax (sodium borate).

First, make a slurry of 10 ounces borax and 4 ounces warm water. Dilute this into 2 1/2 gallons of water. Apply to the lawn area with creeping Charlie. (Read Guide to Killing Creeping Charlie With Vinegar)

This mixture will cover around 1,000 square feet, so adjust the quantities for smaller areas.

Some say this solution can injure your lawn if used more than twice every two or three years to kill weeds.

Are traditional weed killers like Roundup pet safe?

These traditional weed killers are widely used to control weed growth. After all, they make lives easier and backyards tidy.

Unfortunately, the repercussions of these weed killers may be your responsibility.

Keep in mind that not all weed killers are safe for pets. The safety label usually refers to how the weed killer affects humans, but this isn’t always apparent. This information can, and should, alert pet owners.

Glyphosate is a non-selective, environmentally safe lawn herbicide used to control perennial weeds.

It is the world’s most frequently used systemic weed killer, with users of all types. There are over 400 glyphosate-based weed killers on the market, but none are pet-friendly. Roundup Weed and Grass Killer III is the most extensively used and closely followed by Ortho Weed B Gon.

Glyphosate toxicity is most seen in cats and dogs. Especially after coming into contact with lawn weeds that have just been treated. They can be poisoned by:

  • Grass that’s been treated
  • Eye contact or splashing
  • Drinking from the container in which the product had been blended

Chemical weed and grass killer irritate mucosal membranes. It has been connected to glyphosate and the solvent used in commercial preparations.

Clinical indications are primarily digestive when the animal consumes freshly treated grass:

  • Salivation
  • Itching in the mouth
  • Swallowing difficulties
  • Vomiting
  • Diarrhea

Conjunctivitis, with redness and lacrimation, can result from eye contact. Are you prepared to take the chance when there are pet-friendly weed killers? (Learn How To Get Rid Of Dandelions)
