Broadleaf Weed Killer

Broadleaf weeds, such as dandelions, may be easy to spot, but they’re hard to ignore. Persistent and prevalent, these pesky invaders stand out among the uniform grass blades in your lawn and make themselves at home around garden beds and any open crevice on your property.

When it’s time to send broadleaf weeds an eviction notice, you’ll want a weed killer that’s up to this tough job. While pulling these types of weeds may create a temporary solution, if any part of the root is left behind, they’ll only grow back. A high-quality broadleaf weed killer can make a long-lasting impact toward restoring the beautiful look of your lawn and your garden areas.

We’ve rounded up the six best broadleaf weed killers available, provided you with helpful reviews, and included quick-reference pros-and-cons lists and an informative buyer’s guide.

This herbicide is made from ethanol derived directly from corn grain, with no harmful chemicals added. You can use the Green Gobbler with confidence around children, pets, and on every area of your yard.

With an easy-to-use trigger sprayer, you can directly apply it, with no dilution necessary. However, the formula is non-selective and should not be sprayed on plants that you wish to keep healthy or across your full lawn. Also, this product isn’t as effective on rainy, cold, or windy days.

Buyer’s Guide

Before you make a purchase, there’s a few factors to take into consideration when selecting the best broadleaf weed killer for your outside property. In this buyer’s guide, we’ll go over key points to help you find the right product.

Organic versus Chemical-based

When it comes to broadleaf weed killers, it seems difficult to have the best of both worlds in one product. On one hand, you may have a family and pets whom you want to limit coming into contact with harmful chemicals. In this case, especially if you’re also environmentally conscious, you’ll want to select an organic product. Organic and natural broadleaf weed killers generally use vinegar as their formula’s base. While it’s highly effective and fast-acting, you’ll need to apply these products with precision and spot-apply only to weeds. You won’t want to coat your lawn or gardens with it and risk losing plants and grass.

On the other hand, chemical-based broadleaf weed killers are formulated to only kill weeds while not negatively impacting surrounding plants. You can apply it across the entirety of your lawn. However, you’ll need to keep people and pets off your treated lawn until it dries and to be extra safe, up to a day or two afterward.

Finding the Best Value

When determining the best value, you’ll need to look beyond the price. If the product is concentrated, it will last longer and require fewer future purchases. While a ready-to-use product may cost less, you’ll run out of it quicker and need to buy more.

Know Your Grass Type

Finally, northern and southern grass types differ greatly. Be sure to learn your lawn’s grass type, as some products are formulated to work better on certain grass types. Factor in your climate as well. If you live where the temperatures often exceed 90 degrees or your area receives a great deal of rain, you’ll need a product that remains effective under these conditions.

This organic certified product is highly effective on many varieties of weeds and works rapidly within 24 hours. With no harmful chemicals, this broadleaf weed killer is safe to use near children or pets. It comes with an easy-to-use trigger sprayer that requires no dilution.

This product can be applied to your entire lawn, as its specialized formula only kills weeds.
