What is mulch?
Mulch is a layer of material covering the soil, providing the principle benefits of:
reducing evaporation of water from the soil
regulating soil temperatures by providing an insulation layer
helping to control weeds
adding nutrients as it breaks down and plant pathogens suppression.
How do I use mulch?
When mulching try to achieve an even thickness of 75mm (3") over the entire bed but leave a clearance of approximately 25mm (1") around the stalks and stems of plants to avoid collar rot - slightly more for larger plants and trees.
Occasionally rake the surface of the mulch and annually top up your mulch back to the 75mm (3") thickness.
