Rich in nutrients, microbial life, and moisture-retaining cover Soil Builder™ is a vibrant, hand-packed mulch featuring a powerful microbial inoculant ball.

Soil Builder™ Inoculent Ball with labeled elements: Carbon, Nutrients, Trace Elements, and Life.

This living mulch and inoculant ball protects and cools the soil while locking in moisture, resisting wind, igniting microbial life, and bringing a herbal and earthy scent to your garden.

Carbon
Slows decomposition and sustains mulching while bonding with nutrients. We include raw thatch for lasting structure and coverage.

Nutrients
Delivers raw, naturally captured nutrition to the soil, including lucerne for a nitrogen-rich boost.

Trace Elements
Balances the soil with trace elements sourced from salt pan seawater, supplying essential electrolytes.

Life
Jumpstarts microbial activity with living compost concentrates, supported by life-promoting crystals and beneficial metals.

What it looks like, how it’s used and why gardeners love it.

Soil Builder™ is fresh, living, and made to order. Hand-packed into breathable hessian bags that can be composted after use, it is simple to apply and powerful in effect.

Each bag contains 50dm³of mulch and 1 inoculant ball to cover 1 - 2m².

Whether you’re mulching or planting, just one bag goes a long way:

  • Mulching: One bag covers 1 - 2m². Spread the mulch, crumble the inoculant ball over the spread mulch, and water to activate.

  • Planting: Mix 1 part Soil Builder to 3 parts existing soil.

Soil Builder™ is available by the bag at R109,50 each, with custom orders welcome.

  • The mulch stays in place, the soil underneath smells sweet and is teeming with life. It works from sand dunes to clay. I’m a convert!
