Mulching

How to do it

1. 1Apply mulch to already-moist soil, never dry soil, so it locks in existing moisture rather than blocking rain from reaching dry ground.
2. 2Keep mulch a few centimetres clear of stems and crowns to avoid rot.
3. 3A 5-7cm layer is usually enough to suppress weeds and conserve moisture.
4. 4Use well-rotted organic matter for general beds, and an acidic mulch (composted bark or pine needles) for ericaceous plants.
