Best shrubs for shelter and berries in gardens

Why structure matters as much as feeders

A bird table brings birds in, but it does not keep them. If your garden is mostly lawn, a fence and a handful of bedding plants, the birds that visit are making quick raids — down, grab a seed, straight back to a hedge or tree somewhere else. What turns a garden from a snack stop into a place birds actually live is structure: layers of dense, twiggy, berry-bearing shrubbery that provides somewhere to hide, roost, nest and shelter from the wind.

Think of shrubs as the bones of the garden. They break the force of a westerly gale, give small birds a safe route between the feeder and the fence, hold insects through the winter, and produce the berries that carry thrushes and blackbirds through the coldest weeks. Get the planting right and everything else — feeders, nest boxes, a bit of long grass — works twice as hard.

Three shrubs that earn their place

If you only plant three things this winter, plant these. All are native, all are hardy, and between them they cover almost every need.

• Hawthorn (Crataegus monogyna) — the single best all-round shrub for a British garden. It supports a huge range of insects, from hawthorn shield bugs to the caterpillars of dozens of moths, and its haws ripen from September onwards, just as redwings and fieldfares arrive from Scandinavia. Song thrushes use its thorns as anvils for smashing snails. It tolerates clay, wind, salt and hard cutting, and makes an almost impenetrable hedge in four or five years.
• Holly (Ilex aquifolium) — evergreen, so it provides solid winter shelter when everything else is bare, and its berries often hang on until February, which is when they matter most. You need a female plant for berries; if there are wild hollies nearby you may be fine, otherwise plant a male within 30 metres or so. The holly blue butterfly lays on the flowers, and the dense canopy is a favourite roosting spot for wrens.
• Guelder rose (Viburnum opulus) — a lovely, underrated native. Flat white lacecap flowers in May, brilliant red autumn foliage, and translucent scarlet berries in late summer. The berries are stripped quickly, usually by September, so treat guelder rose as an early-season crop rather than a winter larder. Bullfinches take its buds in late winter, and it suckers freely, forming the sort of thick tangle that blackbirds and dunnocks nest in.

Plant in mixed groups, not single specimens

A single holly in the middle of a lawn is decoration. Six shrubs knitted together is habitat. Aim for groups of five to nine plants, spaced roughly 1.5 to 2 metres apart for a shrubby thicket, closer if you want a hedge. Mix the species rather than planting in neat blocks — a berry succession from late summer through to February is far more valuable than a glut in one month.

Two practical points on positioning. First, put your evergreens on the windward side. In most of the UK that means the south-west, the direction our prevailing weather comes from, so the hollies take the battering and the softer shrubs behind them sit in calmer air. Second, vary the heights. Keep hawthorn and holly at 2.5 to 4 metres at the back, guelder rose at 2 to 3 metres in the middle, and let the whole thing come right down to ground level at the front.

Making cover that defeats cats and weather

Cats need a clear runway and a clean pounce. A shrub border with a tidy bare-earth strip underneath it offers exactly that. The fix is to let growth come down to the ground: no gap at the base, no ring of bare soil around each stem.

• Use a thorny outer edge. Hawthorn, or a mixed native hedge, makes a genuinely unpleasant barrier along the side a cat is likely to approach from — usually the fence line.
• Position feeders within about 2 metres of dense cover, so birds can flee instantly, but clear the ground beneath them. A feeder over a shrubby thicket just gives a cat somewhere to wait.
• Check fence gaps and gate bottoms. Cats use the same routes every day, so a thorny shrub planted in the gap at the bottom of a panel will put a stop to it.
• Mulch with well-rotted compost or bark rather than leaving soil bare, and plant low ground cover right up to the stems.

For weather, the aim is a windbreak rather than a solid wall. A permeable band of shrubs slows the wind and creates a calm pocket on the leeward side, which is where birds will feed and roost on a frosty night.

Planting and early care

Bare-root plants, available from November to March, establish better and cost far less than container-grown stock. Plant on a mild, frost-free day when the soil is workable but not waterlogged. Dig a hole twice the width of the roots and to the same depth, fork the base, spread the roots out and firm gently in layers. Container-grown hollies can go in at any time of year, though autumn and early spring are kindest.

• Water thoroughly for the first two summers — around ten litres per plant per week in dry spells. This is the single most common reason new shrubs fail.
• Mulch 5 to 8cm deep around each plant, keeping it clear of the stem.
• Stake only if the site is exposed, and check ties each year.
• Skip high-nitrogen feeds. Rich, sappy growth produces leaves, not berries. An annual mulch is plenty.

Pruning and the year ahead

The golden rule is simple: never cut a shrub between flowering and the point when its berries have gone. Beyond that, a little annual attention will keep everything fruiting well.

• Hawthorn: trim in late winter, once the berries have been stripped. If it is a hedge, cut only a third of it each year on rotation so there is always some fruit.
• Holly: trim in late summer, after flowering but before berries colour, and cut a section at a time rather than shearing the whole plant.
• Guelder rose: remove a third of the oldest stems at the base every second winter to keep it vigorous, and edge around suckers if you want to stop it spreading.

Nothing dramatic happens in the first year. By the third, a wren will slip into the base of the thicket when you walk past, and blackbirds will be nesting in the hawthorn. By the fifth, the first hard frost will bring redwings in, and you will watch them strip the holly over a fortnight while the fieldfares work the haws. That is the point at which the garden stops being a place you visit and becomes a place that lives.
