Compost
Short definition
Compost is dark, crumbly organic matter made from decomposed plant material, used to feed soil and help it hold water.
Good compost smells earthy, not sour. Mixed into beds or spread on top, it adds nutrients slowly and improves soil structure.
Why it matters
In sandy ground, regular compost is one of the simplest ways to help the soil hold water and nutrients that would otherwise drain away.
