What is the Soil Carbon Builder Grass Mix?
The Soil Carbon Builder Grass Mix is a perennial native grass planting designed for long-term soil carbon sequestration and organic matter accumulation. Unlike annual cover crops that cycle carbon through surface residue, these three warm-season grasses build persistent root biomass that transfers atmospheric carbon deep into the soil profile — where it stays. Switchgrass drives deep rhizome networks. Indiangrass adds structural biomass and wildlife value. Sideoats Grama, Texas's state grass, provides drought resilience and fine-textured ground cover in the understory. This is permanent infrastructure for a regenerative operation.

How to Use the Soil Carbon Builder Grass Mix
Site Prep
Control perennial weeds thoroughly before seeding — this is the most critical step. Warm-season native grasses are slow-establishing and cannot compete with aggressive weeds in year one.
Burn down or till weeds in fall, allow one more flush, then terminate before spring seeding. A clean start pays dividends for decades.
Seeding
Drill at 1/8 inch depth into a firm, weed-suppressed seedbed using a native grass drill or Brillion seeder. Do not bury seed deeper than 1/4 inch — these are small seeds that need light and warmth to germinate.
Dormant seeding in November–December allows natural stratification and spring emergence.
Establishment
Expect slow visible growth in year one as the plant prioritizes root development. Mow at 4–6 inches if annual weeds top 10 inches, but do not mow the native seedlings themselves below their growing point.
By year two, warm-season grasses begin to assert themselves. By year three, expect full functional coverage.
Termination or Management
This is a permanent planting — not intended for termination. Manage with prescribed fire every 3–5 years in appropriate regions, or with late-winter mowing before green-up.
These practices reset thatch accumulation, stimulate vigorous new growth, and mimic the natural disturbance cycle these species evolved with.
