Custom Amendment Mix (NCP 33)

EarthWorks NCP33 is a pre-moistened blend of carefully selected organic compost, and aged forest products which are formulated for all landscape planting applications.

The organic compost adds beneficial humus to the soil; the thoroughly composted wood products prevent rapid fiber breakdown.

This complete planting mix may be used for turf and ground cover plating, flower and vegetable gardens, roses, trees, container plants., shrubs, shade plants and acid loving plants.  It is also a superb mulch and topdressing.


  • General soil preparation: 3 cu. yds. per 1,000 sq. ft., till into the top 6"
  • Plant pit backfill: 7 parts native soil to 3 parts planting mix.


  • 1/4" Pine bark, composted wood products, and coffee.
