TRIO Mix, as the name implies, is a mixture of three primary components into an excellent general-purpose soil amendment. It can also be used as the basic component in your custom-potting medium.

Hardwood bark fines, aged pine fines, and mushroom compost are blended in just the right ratio to create this multi-purpose material. It can be used right off the truck as an ingredient in your potting mix or can be added to existing planting beds as a soil amendment.

Application and Usage

For potting applications, use TRIO along with your own custom ingredients when working with woody ornamentals, conifers, annuals, perennials and groundcovers. As a soil amendment, planting beds can be topped with 3 to 4 inches of TRIO and then tilled into the existing material.

Benefits Include:

  • An excellent pre-blended plant pit backfill
  • Stimulate root growth
  • Provides good soil aeration
  • Improves drainage
  • Improves the texture and nutrient value of existing soils

Quantities and Delivery

TRIO is available in full truckload quantities of 50 to 55 cubic yards. Loads may be split with more than one product being delivered on the same trailer. Full truckload deliveries can be made direct to the job-site to eliminate extra handling costs to you.
