When switching to peat-free compost, you might notice that it feels and behaves differently than peat. Peat-free mixes are typically made from a blend of wood fiber, composted bark, and coir. Because these materials drain differently and hold nutrients differently, managing water is key.
Wood fiber provides excellent drainage but can dry out quickly on the surface, while coir holds water like a sponge. When mixing your own potting soil, add coarse grit or perlite for alpines and herbs to prevent root rot. For heavy feeders, mix in a slow-release organic fertilizer or top-dress with seaweed meal. Learning how your peat-free mix holds water will make your container gardening highly successful.
