Our mixes all feature our own compost, which is made specifically this use. This compost is turned and heated to kill weed seeds and disease organisms, and then is carefully aged in a cooler process to stabilize the humus. The presence of a high percentage of compost in our mixes gives them a high level of water and nutrient retention with just the right drainage, and excellent disease suppressive qualities. Our mixes are blended to provide sufficient nutrients for 4 to 6 weeks growth of seedlings, given adequate cell size.  Plants grown in our mixes are ready for continued growth under organic management.
