Quality compost transforms heavy clay (common in Kitsap glacial soils) into a friable, water-retaining growing medium, while also fertilizing existing beds. Unlike fertilizer, compost works slowly and continuously: it improves soil structure, feeds the soil microbiome, and increases water-holding capacity. The result is healthier plants that need less watering and fewer chemical inputs. Curious about the difference between compost and peat moss as soil amendments?
