October Lawn Care in The Woodlands: Brown Patch Fungus, Overseeding, and Fertilizer

As fall settles into The Woodlands, lawns face a unique set of seasonal challenges. Cooler nights and heavier rainfall create the perfect environment for brown patch fungus in St. Augustine grass. At the same time, warm-season grasses like St. Augustine and Bermuda begin transitioning into dormancy, making October the ideal month for overseeding with ryegrass and applying a winterizer fertilizer to keep your lawn healthy year-round.

Brown Patch Fungus in The Woodlands

Brown patch fungus is one of the most common fall lawn problems in The Woodlands. It thrives when temperatures cool and moisture lingers in the soil, especially after seasonal rains or excessive irrigation.

Signs of Brown Patch Fungus:

• Yellowing or browning circular patches

• Most noticeable in low-lying, damp areas

• Rapid spread if left untreated

Treatment Options:

• Apply fungicide from your local garden supply store

• For best results, schedule a professional application through Lawn Ranger’s Green Lawn System

Pro Tip: If you had brown patch fungus last year, chances are it will return in the same areas unless treated with fungicide to break the cycle.

Overseeding with Ryegrass for a Green Winter Lawn

While St. Augustine and Bermuda grass go dormant in fall and winter, overseeding keeps your yard looking lush and green. Overseeding with ryegrass in The Woodlands is one of the best ways to maintain curb appeal year-round.

When Should You Overseed?

The best time to plant ryegrass seed is October through November.

• Annual Ryegrass: Most affordable, widely available, and effective.

• Perennial Ryegrass or blends: More expensive but provides a higher-quality, longer-lasting green appearance into spring.

Will Overseeding Harm My Lawn?

No. Overseeding will not damage your warm-season turf. Instead, it helps by reducing winter weeds and keeping your yard looking healthy.

Advantages of Overseeding in The Woodlands

• A lush, green lawn during the dormant season

• Fewer cool-season weeds

• Year-round beauty for your home’s curb appeal

Disadvantages of Overseeding

• Weekly mowing during winter months

• Extra fertilization needed, since ryegrass competes for nutrients your turf will need in spring

Important Tip: Do not mow until ryegrass has germinated and green blades are visible.

Fertilizer: Why a Winterizer Matters

Fall is the best time to apply a winterizer fertilizer in The Woodlands. This late-season application strengthens roots during dormancy and ensures your lawn greens up faster and healthier in spring.
