Most British gardens have one: the strip behind the shed, the north side of a fence, the ground beneath an old apple tree. It is usually written off as a dead loss — too dark, too dry, too tangled with roots. Yet shade is the natural condition of a wood, and a wood is one of the loveliest things you can make. A woodland garden is simply a garden that copies the layers of a copse: trees above, shrubs and ferns in the middle, bulbs and ground cover below, all knitted together with leaf litter and a path that wanders rather than marches.

Read the shade before you plant

Shade is not one thing, and the difference matters more than any plant list. Dry shade under mature beech, sycamore or conifer is the hardest: the tree roots take the moisture and the soil is dusty by June. Damp shade on the north side of a wall or beside a downpipe is far kinder, and will grow ferns, astilbes and moisture-loving geraniums with ease. Dappled shade beneath birch, rowan or a crab apple gives an hour or two of sun, which is enough for most woodlanders.

• Watch the space for a full day and note how many hours of direct sun it gets, and when. Morning sun with afternoon shade is a gift.
• Push a trowel in 15cm and feel the soil. Crumbly and slightly cool is ideal; bone dry means you will need to water for the first two summers.
• Look up. If the canopy is dense and low, thin a few branches rather than fighting the gloom below.
• Check for compaction and hard pan — a fork worked gently in, without disturbing roots, can work wonders.

Let the leaf litter stay

The single best thing you can give a woodland garden is leaf mould. Rake autumn leaves into a wire cage or a few perforated bin bags, keep them damp, and leave them for a year or two; beech, oak and hornbeam take longest, while lime and sycamore break down quickly. Spread the finished stuff as a mulch 5–8cm deep, keeping it clear of trunks and crowns. It feeds the soil slowly, holds moisture and, crucially, discourages weeds without any digging.

Under trees, put the spade away. Tree roots are shallow and easily damaged, so cultivate with a hand fork at most, and plant in pockets of improved soil rather than turning the whole area over. Plant small specimens in autumn, when the soil is warm and rain does the watering for you.

Plant in layers, not rows

Woodland works because it is stacked. Aim for a loose canopy — perhaps a hazel, a witch hazel or a small ornamental tree — a middle storey of shade-tolerant shrubs, a herbaceous layer of ferns and hellebores, and a ground floor of bulbs, epimediums and wood anemones. Each layer shelters the next, keeps the soil cool and smothers weeds.

• Shrubs: Sarcococca for winter scent, daphne for early flowers, Japanese maple for leaf colour.
• Ferns: Dryopteris filix-mas, Polystichum setiferum and the soft shield fern, planted in groups of three or five.
• Hellebores: Helleborus foetidus and the hybridus types, which flower from January and seed themselves about.
• Bulbs: snowdrops, winter aconites, Cyclamen hederifolium and native bluebells — plant them in drifts, never in neat lines.

Paths and places to pause

A curving path makes a small shaded area feel twice its size, and gives you a dry route through winter. Lay bark chips over a membrane, or set stepping stones into the leaf mould, and edge with cut lengths of hazel or old logs. Do not run a path straight past the best view; let it turn and reveal a group of ferns or a clump of snowdrops. A simple bench at the end, even a log, turns a corridor into a destination.

A year in the woodland garden

In January and February, hellebores and snowdrops carry the garden; tread carefully on frozen ground and enjoy the scent of winter box. Spring brings wood anemones, bluebells and the first unfurling fern croziers, and it is the moment to divide overcrowded clumps. Summer is the garden at its greenest — water only new plantings, leave seedheads standing, and let the shade do its own work. Autumn gives you cyclamen, leaf colour and the main planting window, plus the leaf harvest for next year's mulch. In winter, the structure of trunks, evergreen ferns and mossy logs holds the whole thing together. Work with the shade rather than against it, and that forgotten corner will quietly become the best part of the garden.
