Best Organic Weed Killer Buyer’s Guide

Applying the best organic weed killer will help your lawn to grow healthier and greener without any harm to the environment and people. And the buying guide will help you in selecting the best organic weed killer for your lawn and garden.

Things to Consider When Purchasing The Best Organic Weed Killer

Organic weed killers are very effective in killing weeds and other undesirable plants such as killing broadleaf weeds, lawn weeds, and other types of common invasive plants. It is important to note that using organic weed killers will only kill the targeted plant and not affect the surrounding vegetation.

Before you make a purchase, it is imperative to consider several things especially if you plan on purchasing for commercial purposes or use in large-scale applications. First, ensure that the product has been approved by USDA under National Organic Program (NOP). In addition, ensure that it contains natural ingredients that have been proven safe when used by humans including pets and animals. More importantly, ensure that the product is labeled as an organic weed killer.

When shopping for an organic weed killer, keep in mind that are three different types of these remedies available for sale namely; contact weed killers, selective weed killers, and systemic weed killers.

Contact Weed Killers

A contact weed killer is applied to the foliage of the plant and will immediately kill it; they are effective in killing broadleaf weeds, dandelions, grasses, shrubs, and other types of unwanted vegetation. Contact organic weed killers are usually liquids or powders that can be sprayed on leaves that have been thoroughly wetted with water after being stirred to ensure even coverage.

This type of organic remedy should not affect surrounding vegetation because they kill only on contact. Further, some contact herbicides are highly selective meaning that they can be used to control undesired plants without disrupting desirable plants growing nearby. A good example of a suitable contact organic remedy includes corn gluten meal which is a by-product produced during the process of corn milling.

Selective Weed Killers

A selective weed killer contains chemicals that are designed to kill specific types of weeds without causing any damage to surrounding vegetation. It is important to note that these organic remedies are not effective in controlling broadleaf weeds because they prevent new weed seeds from germinating.

However, they can be used on mature plants and grasses with minimal or no adverse effects on nontarget plants. A good example includes vinegar-based mixtures which have been proven safe for animals including dogs and cats when applied directly onto hairs of their coats. As with contact herbicides, you must ensure that the product has been approved by USDA before making your purchase decision.

Systemic Weed Killer

Lastly, a systemic herbicide is designed to penetrate the plant and kill it from its roots. This type of organic weed killer can be used on annual weeds such as crabgrass, dandelions, and clover without destroying surrounding grasses. A good example of a suitable systemic organic remedy includes corn gluten meal which prevents the germination of weed seeds without killing surrounding vegetation.

Type of Weed and Grass

Before buying any weed killer for your area. Make sure, to know about the type of grass and weed on your lawn. Because weed killer works for specific weeds and grass. And if you buy the wrong product, you might burn your lawn.
