McGill SoilBuilder Compost



McGill SoilBuilder Compost rebuilds poor soil by increasing organic matter, replenishing the soil microbes responsible for nutrient uptake and improving water management.
It’s ideal for use as a topdressing, soil amendment, or mix ingredient.

Manufactured from 100% recycled content, McGill SoilBuilder compost is a product you can feel good about.  It makes lawns, turfgrass, gardens and ornamentals look great while helping the planet. But best of all, SoilBuilder compost is cost-effective and offers outstanding performance:

  • Reduces irrigation requirements up to 50%
  • Reduces stormwater runoff up to 50%
  • Reduces pollutant loads in stormwater runoff
  • Improves percolation for better drainage
  • Holds more nutrients at the root zone
  • Improves nutrient uptake
  • Reduces compaction for better root development

McGill SoilBuilder compost is easy to spread, mix and use.  The general rule of thumb is 1/4 to 1/2 inch if applying to the top of the soil.  If working into the soil, add 1 to 2 inches for every 6-8 inches of soil depth.  Recommended maximums are 30% compost in a soil blend, but no more than 25% compost in containers or raised beds.

Fruits, vegetables, ornamentals:  For raised beds blend up to 25% SoilBuilder with 75% or more native soils. Use 1 to 2 inches of SoilBuilder in native soil beds and incorporate to a depth of 6 to 8 inches, plant and water. Condition this way every other year.

Trees, shrubs: Dig a hole the same depth as the root ball and two to three times as wide. Mix up to 25% SoilBuilder with 75% soil saved from the planting hole. Place the plant in the planting hole and apply amended soil around the root ball. Firm the soil as the hole is backfilled and water thoroughly.

New turf areas: Apply 1 to 2 inches of SoilBuilder to existing soil and incorporate to a depth of 6 to 8 inches. Apply seed or install sod; rake and water.

Topsoil manufacturing/ upgrading: Mix 1 part SoilBuilder with 3 to 4 parts soil and blend.
