When it comes to keeping your warm-season lawn free from stubborn broadleaf and grassy weeds, Celsius WG is a top choice for both DIYers and lawn care pros. This professional-grade herbicide offers reliable, heat-tolerant weed control without the guesswork. Here’s what you need to know about using Celsius WG to keep your lawn lush and weed-free.
What Is Celsius WG?
Celsius WG is a post-emergent herbicide formulated as a water-dispersible granule (WG), designed specifically for warm-season turfgrasses like St. Augustine, Bermuda, Zoysia, and Centipede. Unlike many herbicides, Celsius WG has no labeled heat restrictions, making it safe to use even during the hottest summer months. The new single-use packs take all the hassle out of measuring, making it perfect for DIYers who want professional results with minimal fuss.
What Weeds Does Celsius WG Control?
Celsius WG is highly effective against:
- Broadleaf Weeds: Dollarweed, clover, Florida pusley, spurge, Virginia buttonweed, and more.
- Grassy Weeds: Large crabgrass, carpetgrass, dallisgrass (suppression), and others.
- Hard-to-Control Species: Doveweed, lawn burweed, American burnweed, and over 150 other weed varieties.
This broad spectrum makes Celsius WG a versatile solution for tackling the most common and persistent weeds in warm-season lawns.
When Should You Apply Celsius WG?
Timing is key for effective weed control:
- Post-Emergent Applications: Apply when weeds are actively growing and visible in your lawn. Celsius WG works best on young, tender weeds but can also control mature weeds with patience and, if needed, a follow-up application.
- Warm-Season Lawns: Use on Bermuda, St. Augustine (including Floratam), Zoysia, and Centipede grasses. Do not use on Bahia or cool-season grasses.
- Heat Tolerance: Celsius WG can be applied even in the peak of summer, making it ideal for southern lawns.
How to Apply Celsius WG
- Choose the Right Pack: The single-use pack covers 4,000 sq ft at the low rate or 2,000 sq ft at the high rate.
- Mixing: Add the packet to your sprayer (battery or pump sprayer recommended), fill with the appropriate amount of water (4 gallons for low rate, 2 gallons for high rate), and agitate well.
- Application Method: Spray evenly over the target area. For blanket applications, follow the annual maximum use rates. For spot treatments, you can apply as needed.
- Add a Surfactant: For best results, use a non-ionic surfactant to help the herbicide stick to weed leaves.
- Watering In: Do not water in after application. Avoid applying if rain is forecasted within 48 hours.
Integrating Celsius WG Into Your Lawn Care Routine
- Monitor for Weeds: Regularly inspect your lawn for new weed growth and treat as needed.
- Combine with Good Practices: Proper mowing, watering, and fertilization help your lawn outcompete weeds and recover from stress.
- Follow Label Rates: Avoid over-application by sticking to recommended rates and annual limits.
Safety and Environmental Tips
- Keep Children and Pets Off Treated Areas: Until the spray has dried.
- Avoid Drift: Do not spray on windy days or near desirable plants.
- Storage: Store in a cool, dry place away from sunlight and out of reach of children.
The Bottom Line
Celsius WG is a powerful ally in the fight against tough lawn weeds, offering both convenience and professional-grade results for warm-season lawns. By understanding when and how to use it, you can keep your lawn looking its best all season long—without the hassle of complicated measuring or heat restrictions.
