Buying Guide for Pre-Emergents for Zoysia Grass
Selecting the right pre-emergent herbicide for your Zoysia lawn involves considering multiple factors:
1. Active Ingredient
Prodiamine is a commonly preferred active ingredient due to its efficacy against a broad range of grassy and broadleaf weeds. It is effective in multiple products reviewed here and offers reliable season-long control. Other ingredients like oxadiazon are also used but may vary in target weeds and safety.
2. Application Type
Granular products provide ease of application and can be spread evenly on the lawn, while liquid or spray forms often allow more precise coverage but may require additional equipment like sprayers. Hose-end sprays like the Sunday Weed & Green offer simple application without mixing.
3. Coverage Area
Choose a product that aligns with your lawn size for cost-effectiveness. For example, granular products like The Andersons Barricade cover thousands of square feet, while sprays may have smaller coverage and suit smaller yards.
4. Timing and Climate
Pre-emergents must be applied before weed seeds germinate. Monitoring local soil temperatures (usually around 50-55°F) is essential to schedule application correctly—early spring and fall are common times. Consider products that specify season-long protection for extended control.
5. Target Weed Spectrum
The best pre-emergents for Zoysia grass are effective against both crabgrass and broadleaf weeds common in warm-season lawns. Verify the label to ensure your prevalent lawn weeds are covered.
6. Safety and Turf Compatibility
Ensure the herbicide is safe for Zoysia grass and other landscape plants in your lawn to prevent damage. Check for any restrictions on use around ornamentals, pets, or children.
7. Additional Lawn Benefits
Some products, like weed-and-feed combinations, offer lawn fertilization or enhancement alongside weed control. Consider whether you want a multi-purpose product or a dedicated pre-emergent.
