3 Best Weed Killers for Zoysia Grass

Zoysia Grass

Zoysia grass is a low maintenance option for high traffic yards. Unfortunately, it is not immune to pesky and invasive weeds. Selecting the best weed killer for Zoysia grass is an essential step to keeping your yard in top shape.

This article features our recommendations for the best herbicides for your Zoysia grass lawn.

Best Pre-Emergent Weed Killer for Zoysia

Pre-emergent herbicides are your first line of defense against weeds. You shouldn't fertilize zoysia in the winter. However, the winter is a great time to apply a pre-emergent herbicide to the lawn. Applying pre-emergent products in the winter ensures a more attractive lawn in summer.

Pre-emergent herbicides form an invisible barrier that prevents seeds from germinating. Stopping the germination will stop weeds before they even begin.

Once applied, most pre-emergent herbicides will remain effective for 30-60 days. Many products may need another application as temperatures rise. Pre-emergent products will not kill existing weeds in the lawn.

Pre-emergent herbicides prevent weeds, they do not kill existing weeds.

Best Granular Pre-Emergent Weed Killer for Zoysia

Ferti-Lome Broadleaf Weed Control is a pure pre-emergent herbicide. It is excellent for use in Zoysia grass. It does not contain any fertilizers, making it a perfect winter application choice.

Ferti-Lome Broadleaf Weed Control stops many types of invasive weeds in their tracks. It does not rely on cornstarch like many herbicides. Isonxaben is the main ingredient and is very potent. Those small differences make it ultra-effective and long-lasting.

Apply the product at a rate of 5 pounds per 1,000 sq ft. A 10-pound bag is ample for most midsize yards. As with most granular products, you need a half inch of water to activate the product.

Best Liquid Pre-Emergent Weed Killer for Zoysia

Dimension 2EW Herbicide is a professional-grade, pre-emergent herbicide. It keeps your lawn weed-free for weeks on end. It is so professional that your signature will be required when it's delivered!

The non-staining and low odor formula will mix in sprayers and is safe after the product dries on the turf.

Dimension's product prevents crabgrass, smut grass, along with 40 other weeds. The lawn must receive a half inch of water within seven days of application to activate the product. As with all herbicides, follow the manufacturer's safety instructions and application rates.

Best Post-Emergent Herbicide for Zoysia

Post-emergent products will kill weeds that have already taken root. They do not prevent weeds from growing but will kill them once they are.

Applied later in the growing season, post-emergent products have a shorter life span and need several applications. Post-emergent herbicides come in liquid and granular forms.

Best Liquid Post-Emergent Weed Killers for Zoysia

Bonide Weed Beater Ultra

Bonide Weed Beater Ultra kills over 200 different varieties of weeds in zoysia lawns. Designed for cooler weather, Weed Beater is a perfect herbicide late Fall or Early Spring.

Weed Beater uses a combination of four unique herbicides to provide great results. Bonide's product also uses systemic and contact herbicides, making it a well-rounded option.

Spot treating is an option with a liquid herbicide if a particular lawn area is suffering from a weed infestation. The application area's size will determine if a handheld, backpack, or vehicle-mounted sprayer is needed.
