A premium high-test potting soil. Formerly branded as Ithaca Blend (some bags still labeled that way). Coir, sphagnum peat, and worm castings form the base of this top-quality mix; GreenTree’s own biochar is added to encourage a thriving microbial population, and the whole concoction is topped off with a generous well-balanced helping of organic nutrients.
Highly recommended for indoor growers, container gardening, or slow-growing seedlings that will be in the greenhouse for six weeks or more. Seth Yentes of North Branch Farm said his onion seedlings thrived best in this soil. He observed that it has excellent water-retention capacity, and it doesn’t get slimy on top like some organic potting soils. Made in New York. Now owned by bio365, based in California. MOFGA
