Zoysia Grass Pre-Emergent

About

Keep your Zoysia lawn weed-free and looking its best year-round with our premium pre-emergent products. Zoysia grass thrives in warm climates, but unwanted weeds like crabgrass, goosegrass, and annual sedges can quickly take over if not stopped early. Our specialized Zoysia grass pre-emergent herbicides create a protective barrier in the soil to prevent weed seeds from sprouting—before they become a problem. Whether you're preparing your lawn in early spring or fall, our pre-emergents are formulated to support Zoysia's slow-growing habit while offering added nutrients to keep your lawn healthy. When to Apply Pre-Emergent to Zoysia Grass Timing is everything. For the best results, apply pre-emergent to your Zoysia lawn twice a year: Early Spring (Jan 15 – March 15): Apply before soil temps hit 55°F to block crabgrass and other spring/summer annuals. Early Fall (Sept 1 – Oct 15): Apply before soil temps drop below 70°F to prevent Poa annua and winter weeds. Avoid applying if you plan to seed or overseed—pre-emergent will prevent both weeds and grass seed from germinating.
