The wettable granular formulation is designed for lawns and outdoor spaces that feature St. Augustinegrass, Bermudagrass, Centipedegrass, and Zoysiagrass. This product is labeled for residential and commercial lawns as well as golf courses, sports fields, parks, campsites, and other managed green spaces.\u003c\/p\u003e\u003cp\u003eFrom the moment you apply Celsius WG, weeds begin to respond. The active growth slows within hours, and affected plants progressively yellow, redden, and then necrotize, typically finishing within 1 to 4 weeks depending on temperature and weed maturity. Warm days speed the process, while cooler conditions slow symptom development. For best results, apply when daily average temperatures exceed 60°F and target actively growing weeds.\u003c\/p\u003e\u003ch2\u003eKey benefits and performance highlights\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBroad-spectrum control of 120+ annual and perennial broadleaf weeds and grasses.\u003c\/li\u003e\n\u003cli\u003eEasy-to-use format with no measuring required—just mix and apply.\u003c\/li\u003e\n\u003cli\u003eProfessional-grade, golf-course quality performance for large and small spaces alike.\u003c\/li\u003e\n\u003cli\u003eFast-acting results that help turf rebound quickly after application.\u003c\/li\u003e\n\u003cli\u003eSafe on St. Augustinegrass and other common warm-season varieties when used as directed.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHow to use Celsius WG\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eApply to actively growing weeds, ideally on days with daily average temperatures above 60°F.\u003c\/li\u003e\n\u003cli\u003eAvoid applications when heavy dew, fog, mist, or rain is imminent or present; drought-stressed weeds may respond slower.\u003c\/li\u003e\n\u003cli\u003eEnsure the product is used as labeled, targeting appropriate warm-season turf areas such as lawns, golf courses, sports fields, parks, and sod farms.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eOverall, Celsius WG provides a practical option for managing weed encroachment in warm-season turf.
