Composting & Soil Improvement

Practical advice on composting, mulching and improving soil structure to help gardens thrive in East Dean, Friston and the South Downs.

Why healthy soil matters

Healthy soil is the foundation of a successful garden. Good soil supports strong root growth, improves water retention, encourages beneficial organisms and helps plants cope with periods of drought, pests and disease.

In East Dean and Friston, many gardens have chalky, free-draining soil. Regular additions of compost and organic matter can help improve soil structure and moisture retention while supporting a thriving soil ecosystem.

Composting and soil improvement ideas

  • Make garden compost from suitable green and brown materials.
  • Use well-rotted compost as a mulch around established plants.
  • Collect autumn leaves to make leaf mould for soil improvement.
  • Add organic matter regularly to help chalk soils hold moisture.
  • Use compost to improve planting holes, but avoid over-enriching plants that prefer poor soil.
  • Mulch in spring to reduce moisture loss during summer.
  • Reuse suitable garden waste where possible rather than sending it away.
  • Improve soil gradually over time rather than trying to change it all at once.

Simple composting tips

  • Balance softer green material with drier brown material such as shredded prunings, cardboard or dry leaves.
  • Avoid adding cooked food, meat, dairy products or diseased plant material to ordinary garden compost bins.
  • Keep compost moist but not waterlogged.
  • Turn or aerate compost occasionally to help it break down more quickly.
  • Site compost bins somewhere accessible so they are easy to use regularly.
  • Use finished compost when it is dark, crumbly and earthy-smelling.
