Preparing Warm-Season Turfgrass for Winter

Transitioning warm-season turfgrass for the winter can be a challenging process. As fall sets in, days grow shorter, sunlight intensity drops, and cooler temperatures slow top growth. Add in heavier traffic from peak-season play, and you’ve got turfgrass under real pressure. Yet expectations for high-quality playing conditions don’t go away. If anything, they climb.

Foliar-Pak offers targeted solutions that make this job easier. By applying a foliar or soil spray with a few select Foliar-Pak products, you can strengthen your warm-season turfgrass, protect it from stress, and give it the energy it needs to perform through the busy winter months.

Foliar Spray: Four Key Foliar Products

Foundation Forty
Foundation Forty helps warm-season turfgrass make the most of limited sunlight. It boosts photosynthesis and carbon assimilation, giving the plant a better chance to build carbohydrates when conditions aren’t ideal. Its amino acids also improve nitrogen use, which means the plant conserves valuable carbs for storage instead of burning through them too quickly.

Amperage
When sunlight fades, carbohydrate production naturally slows. Amperage fills the gap by supplying key micronutrients for photosynthesis while adding carbon sources that supplement reserves. The result? Better color, stronger health, and more stored energy heading into winter.

CSi L
High traffic is one of the biggest threats to warm-season turfgrass in the winter. With slower recovery, worn areas can quickly become eyesores. CSi L helps toughen leaf tissue by strengthening cell walls and cuticles. It also includes amino acids that help regulate water inside plant cells, allowing turf to withstand dry conditions, salt stress, and poor-quality irrigation water.

Gold Standard 45
Cooler weather brings environmental stressors that don’t let up—shade, low light, and fluctuating temps. Gold Standard 45 helps warm-season turfgrass cope by supporting stress tolerance, improving resilience, and keeping playing surfaces consistent even under harsh conditions.

Soil Spray: Three Key Soil Products

Colonise® Bio
As temperatures drop, warm-season turfgrass leans on its root system to store energy and carry the plant through the colder months. Colonise Bio helps by maintaining high root density, providing the turf with a larger, healthier root mass going into winter. At the same time, it boosts soil health by supporting beneficial microbes, building a stronger foundation for turfgrass to withstand winter stress and bounce back quickly in spring.

Armament® K
Warm-season turfgrass shifts its energy focus below ground when temperatures cool and daylight hours fade, storing carbohydrates in its roots and stems to survive winter. Potassium is essential here, driving those carbohydrates from the shoots into storage tissues so reserves are ready when energy production slows. By supplying potassium, Armament K helps turfgrass boost its storage of energy reserves, allowing it to maintain quality during heavy winter play.

Armament® P
Armament P makes sure the plant’s “engine” keeps running. Phosphorus is critical for ATP production, the molecule that powers nearly every plant function. In low-light, cooler conditions, when photosynthesis and growth are naturally limited, phosphorus is essential for keeping basic processes moving. Applying Armament P helps make sure phosphorus is not limited, so the plant doesn’t suffer from the inability to drive plant reactions and fail.

Why Timing Matters

The key is timing. Starting early in the fall with Foliar-Pak products gives turf the best chance to store energy and stay resilient when conditions turn harsh.
