Custom Soil Blends & Growing Mediums


  • Laboratory testing forms the basis of everything we produce.
  • We purchase and stock large volumes to produce predictable and cost effective blends.
  • We focus on locally available ingredients whenever possible.
  • We can produce imported soil or provide amendments to improve existing site conditions.

Why Should Architects and Engineers Specify Soil?

  • Quality Control – Landscapers will provide the bare minimum unless otherwise specified.
  • Provide clarity in the bidding process – Contractors can provide apples for apples pricing.
  • Landscaping and infrastructure installations are expensive and generally soil is a fraction of the input costs.
  • Using untested soil is risky as it can negatively affect the health of plants and limit projects ability to meet performance expectations.
  • We have compiled test Data on dozens of soil stockpile sources in the region and have found most to be undesirable for soil blends or direct plantings due to high clay and low organics.

We create custom media blends by finding a balance of the following factors:

  • Determining what the desired performance characteristics are.
  • Sourcing predictable, readily available cost effective ingredients.
  • Verifying quality and function through extensive lab testing.
