The foundation of Sunshine® Advanced Mix #4 is Canadian Sphagnum peat moss, sustainably harvested from carefully managed bogs in rural Canada. The peat moss is blended with horticultural grade perlite, coir, dolomitic lime, a starter organic fertilizer, mycorrhizae and an organic wetting agent to complete the mix. Lime adjusts the pH for optimum fertilizer availability, the starter organic fertilizer helps transplants establish, mycorrhizae assists in fertilizer uptake and the organic wetting agent helps peat moss absorb water better.
