Mulching feeds the beds. As leaves decompose over winter, they release nitrogen and other nutrients into the soil. Earthworms and other soil organisms feed on the leaves and produce concentrated fertiliser as a result;
Insects and worms attracted by the mulch help to keep the the soil surface loose and oxygenated, creating a nurturing environment for plant roots, beneficial fungus and microorganisms
Mulching protects plants from drying out during long cold spells. The real danger to plants in winter locally isn't the cold, it's desiccation. The freezing air temperature sucks the moisture from soil and plants, causing them to dry out and die. Mulching helps prevent the soil from drying out and also creates a barrier against wind.
This effect continues into summer. Leaving some mulch in place over summer will reduce evaporation and watering needs.
Mulching helps keep weeds down. Mulch helps stop weeds from taking root or thriving in garden beds, making maintenance much easier.
Mulching provides over-wintering protection for the caterpillars of butterflies, ladybugs and lacewings, and many other beneficial insects. More mulch, more butterflies!
Mulching creates rich winter feeding areas for small birds. All those leaves hide insects and seeds which attract all kinds of small to medium size bird species. It's an easy and natural way to encourage birds and provide entertainment for residents and staff.
