Inch by Inch AZ Worm Castings

Soil Builder Mix

What is it? Our Soil Builder is exactly what it sounds like: a great material to combine with compost or native soil to build a planting base for your beloved plants.

Soil Builder contains:

  • our premium castings
  • straw
  • wood chips
  • compost

It is much coarser than our pure castings, making it slow-release with drainage and aeration properties.

Overs Builder contains:

  • The same as Soil Builder, just larger chunks and less processed.

Use: Soil Builder is an excellent solution for building a planting bed. It can also be used as a top dressing for trees and shrubs.
