Compost Plus

Booster Mix

A premium supplement designed to rejuvenate "tired" soil in containers or garden beds. It provides a blend of minerals and organic matter to improve the structure and fertility of existing growing media when immediate fertility is needed. This mix will not burn roots. Compost Plus is approved for use on certified organic farms.


Blended from composted manure and plant materials, blonde horticultural grade sphagnum peat moss, crushed and screened granite and basalt, blood meal, kelp meal, steamed bone meal, mined gypsum, vermiculite (a mica mineral expanded by fire), washed coconut coir, herbs (biodynamic preparations).

Best Practices

Prep For Use:

Apply as-is and water-in or create a slurry with warm water before application.


Avoid drastic changes in moisture/saturation. Store under cover, out of direct sunlight. Protect from weed seed, petroleum products, and other contaminants.

Supplemental Fertility:

If necessary, use after six weeks of seedling growth or during transplanting. Re-apply when immediate fertility is needed. For best results, add 1 cup of Compost Plus per 1 quart of planting media.

Storage and Shelf Life:

Store in a neutral environment which encourages moisture retention and protects from UV light. For optimal performance of living soil we suggest using it within 8-12 months from date of purchase.
