How to Help Wildlife Thrive in Autumn in Your Garden

Updated

You can help autumn wildlife with two simple garden actions the RSPB highlights: use fallen leaves to build a warm winter shelter for hedgehogs and toads, and leave seedheads standing so birds and other wildlife have food through the colder months. Both need no special equipment and fit into ordinary garden tidying — in fact, they often mean doing a little less.

Build a leaf shelter for hedgehogs and toads

The RSPB suggests using leaves to create "a warm and cosy winter sleepover for hedgehogs and toads." The idea is to gather fallen leaves into a sheltered corner rather than clearing them all away.

  • Choose a spot: a quiet corner under a hedge, behind a shed, or beneath dense shrubs — somewhere damp, shaded and undisturbed.
  • Pile the leaves: heap them into a mound roughly the size of a small armchair, and add a few twigs or logs at the base to let air in.
  • Leave it alone: avoid moving or compacting the pile through winter, and keep dogs and children from digging into it.
  • Expected result: a dry, insulated space that hedgehogs and toads can use to hibernate, plus cover for insects that become food for other wildlife.

If you already have a compost heap or a log pile, a leaf pile next to it creates a connected patch of shelter rather than an isolated one.

Leave seedheads standing

The RSPB's autumn activity guidance is to "leave your seedheads standing to provide precious food for birds and other wildlife." This applies to plants such as teasels, sunflowers, coneflowers and ornamental grasses.

  • Delay cutting back: hold off on tidying perennials until late winter or early spring, once seed has been eaten.
  • Pick the right plants: single-flowered varieties produce accessible seed and nectar; heavily double-flowered types often offer little.
  • Expected result: a natural food supply for finches, tits and sparrows, and overwintering cover for insects.

When you do cut back in spring, leave the stems in a bundle in a corner for a few weeks so any insects inside can emerge.

Other simple autumn actions

Beyond the two RSPB highlights, a few low-effort steps complement them:

Action What it does
Leave some fallen fruit under trees Food for thrushes, blackbirds and insects
Avoid disturbing leaf piles and log stacks Protects hibernating animals
Keep a shallow dish of water Drinking and bathing water when natural sources freeze
Delay hedge cutting and strimming Avoids disturbing nests and shelters

The RSPB also runs broader seasonal guidance on feeding garden birds, including feeding seasonally and feeding safely — useful if you want to support birds through winter as well as autumn.

Why these small actions matter

Autumn tidying removes exactly the features wildlife depends on: leaf litter for hibernation, seed for food, and standing stems for shelter. Leaving a corner of the garden "untidy" creates a small habitat patch that supports local biodiversity — insects first, then the birds and mammals that feed on them. The RSPB frames this as part of helping wildlife thrive together, and it costs nothing beyond a change in routine.

Where to go next

If you want to see these habitats in practice or get more involved, the RSPB website offers a reserve finder, a species search, volunteering opportunities and guidance on what to do if you find an injured bird. Membership includes access to over 170 nature reserves across the UK, which can be a good way to see managed autumn habitats first-hand before recreating them at home.
