The advice goes: you must take away fallen leaves from round vegetation to scale back slug and snails and to keep away from shading the vegetation. Each of those items of recommendation are counterintuitive and I’ll clarify why.

1) Fallen leaves are the wild means

As I clarify commonly in my Wild Means E-newsletter, if we glance to nature, it is going to inform us all the things we have to find out about rising in gardens. Within the wild, leaves fall and this kinds the idea of most natural matter that powers development the next 12 months. The leaves decompose thanks to numerous organisms within the ecosystem, which incorporates slugs and snails, as effectively fungi, micro organism and different microorganisms. Folks typically ask me “what’s the level of slugs?” and the reply is straightforward, one in every of their essential roles is to interrupt down fallen leaves, recycling it as nutrient wealthy humus that vegetation use for development sooner or later.

In reality, the leaves supply a layer of safety from the winter parts. When you’ve got smaller evergreen vegetation you possibly can brush the leaves off or, personally, I’d transfer them to a extra applicable place or exchange them with one thing extra tolerant. Ferns as an illustration will be evergreen however are additionally extraordinarily shade tolerant, shade loving vegetation like this received’t bat a leaf a couple of skinny layer of leaves in winter.

4) Fallen leaves don’t final lengthy in a wholesome ecosystem

Most fallen leaves will blow round vegetation and start decomposing rapidly, particularly with a wholesome ecosystem that features slugs and snails. Above you possibly can see how the leaves that fell from a really massive rowan, birch and an amelanchier have nearly all been absorbed into the soil inside a month or so. It’s true that some timber like oak and beech have more durable leaves that take for much longer to decompose. Nevertheless, these make incredible habitats for useful animals like frogs, toads, gradual worms and hedgehogs. It simply requires bigger vegetation like massive ferns that the leaves will fall round and never on.
