Warm Season Lawns: Winterizer Value Pack | Yard Mastery

Warm-Season Winterizer Pack | Stress Blend, Humic12 & Air-8 Fall Lawn Fertilizer

Put your warm-season lawn to bed the right way with the Yard Mastery Warm-Season Winterizer Pack. This late-fall lawn pack combines 7-0-20 Stress Blend granular fertilizer with Humic12 liquid humic acid and Air-8 liquid aeration. Together, they feed the soil and reduce stress on Bermuda, St. Augustine, zoysia, centipede, and bahia lawns heading into dormancy.

For warm-season grass, “winterizer” means something different than most people think. It’s the last application of the year, but the goal isn’t to push growth. It’s to feed the soil and help the turf handle stress as it goes dormant. Southern lawns usually don’t get snow cover, so they face foot traffic, wind, weeds, and disease all winter long. Buying the products together as a pack saves 25% versus buying them separately.

When to apply: Use the Warm-Season Winterizer Pack if you’re still mowing your lawn at least every 10–12 days. If your lawn has already gone dormant and you’ve stopped mowing, it’s too late to use the fertilizer in this pack this season. You can still apply bio-stimulants, plus a pre-emergent to stop weeds.

How the Winterizer Pack Works

• 7-0-20 Stress Blend is high in potassium and low in nitrogen. Potassium helps grass handle stress from cold, traffic, drought, and disease. The low nitrogen feeds the lawn without forcing a flush of new growth right before dormancy.
  
• Air-8 penetrates the soil and opens space for air and water to move into the root zone. Humic12 then adds carbon to that space, improving soil structure and supporting healthy roots.
  In the South, the soil usually doesn’t freeze, so it stays somewhat active even after the lawn goes dormant. Feeding the soil now helps your lawn come out of dormancy stronger in spring.
