Leaf mould at WeGrowOrganic

Autumn leaves into fungal-rich gold

Leaf mould is the crumbly, dark, fungal compost that forms when autumn leaves break down slowly on their own — the single best soil conditioner you can make for free.

It takes patience (12–24 months) but the result is unbeatable: a spongy, moisture-holding mulch that transforms tired beds and feeds fruit trees, ferns and shade plantings.
