Patio Plus has a slightly smaller particle size and includes more peat moss, making it a better application for small pots/containers which require more moisture retention. Patio Plus also contains aged rice hulls to help support better drainage due to it's smaller particle size and dolomite and oyster shell limes to help balance soil pH in smaller containers.
Raised Bed & Potting Mix has a slightly larger particle size eliminating the need for aged rice hulls and contains less peat moss. We added coir for additional moisture retention for larger containers such as raised beds. This helps reduce clumping found in more peat based soil mixes used in larger container applications.
