How to Kill Weeds with Herbicides

What You Need to Know to Stay Safe


Spraying Herbicide to control weeds

What’s one thing any gardener can grow without even trying? Weeds. Controlling and killing weeds with herbicides is one way to gain back your garden. Since herbicides contain chemicals that could be harmful, take great care and consideration with their use.

Types of Herbicides

Strolling down the herbicide aisle of your local lawn and garden store, you’ll notice there are plenty of options. These options fall into the following categories:

Pre-emergent herbicides – target weed seeds or form a barrier in the soil to prevent germination. Use in the spring to prevent crabgrass seeds from establishing. Timing is important in controlling the weeds before they start to emerge. Used correctly, you can control weeds for several months.

Post-emergent herbicides – target actively growing weeds. Apply selective herbicides to the weeds in your lawn without killing all your grass. Grass-like weeds can be harder to selectively target with herbicides. Use non-selective herbicides, like Round-Up, sparingly since it will kill everything it comes in contact with, including your grass. This type of herbicide needs extra care while applying to prevent spilling.

Controlling Weeds with Herbicides

Herbicides commonly come in granular and liquid form. Apply granular herbicides with a push-type spreader or mix with fertilizer. Since granular applications are spread over a large area, you could be applying chemicals in places that may not need it.

Dilute liquid herbicides with water and spray directly on weeds. Spot spraying broadleaf weeds, like dandelions or clover, with a selective, post-emergent herbicide can save your lawn from excessive chemicals.

How to Safely Use Herbicides

Using chemicals on your lawn so close to pets and children should be done carefully. Read and follow all directions thoroughly. Some herbicides are made for only certain weeds, so be sure to use the right one for your needs. While some results are instant, other products take weeks to work. Some products may require repeated applications for effective control. When using any form of herbicide, be sure to protect yourself, your family, and the rest of your lawn and plants.

While the majority of herbicide application can be done by homeowners, hiring a licensed professionals helps ensure the use of herbicides is done safely and correctly. Contact Cardinal Lawns for more ways to combat weeds in your lawn.
