Why a native hedge earns its space

Few garden features work as hard as a native hedge. In a single run of ten or fifteen metres you get nesting cover, winter berries, spring blossom, summer nectar and a sheltered corridor that lets small mammals and insects move safely between gardens. Unlike a fence, it changes with the seasons and improves with age.

Hawthorn, blackthorn and hazel sit at the heart of a good British mixed hedge, and for good reason. They are tough, they tolerate most soils, and between them they feed dozens of species. Hawthorn alone supports more than 300 insect species, and its haws are a vital winter larder for redwings and fieldfares.

You do not need a large plot. Even a five-metre stretch along a boundary or the end of a lawn will make a difference, particularly if neighbouring gardens have hedges too. Think of it as stitching your garden back into the wider landscape.

Choosing the right mix of species

Aim for five to seven species, with one or two making up the bulk of the planting. Hawthorn (often sold as quickthorn) should usually be the backbone — around 60 per cent of the mix. It is dense, thorny, quick to establish and generous with both blossom and berries.

Then add interest and extend the season with the following:

• Blackthorn — clouds of white flowers in March, before almost anything else, and sloes for gin in autumn. It suckers freely, so give it room or a wild corner.
• Hazel — yellow catkins in February, nuts in September, and it coppices beautifully if you ever want to cut it back hard.
• Field maple — good autumn colour and a favourite of aphids, which in turn feed blue tits.
• Crab apple — blossom for bees and fruit that blackbirds will strip by November.
• Dog rose and guelder rose — hips and berries, plus lovely foliage. Guelder rose has excellent autumn colour.
• Holly — slow-growing but invaluable for winter shelter and berries, and it will tolerate shade.

If your soil is heavy clay, add a little dogwood or spindle. On light, chalky ground, wayfaring tree and buckthorn do well. A mixed hedge will always outperform a single-species one for wildlife, so resist the temptation to plant a neat row of one thing.

Bare-root planting: the winter advantage

The single best money-saving decision you can make is to buy bare-root plants rather than container-grown ones. Bare-root whips are lifted from the field while dormant, usually between November and March, and sold without soil around the roots. They cost a fraction of potted stock, are far lighter to carry, and in most soils they establish more quickly because the roots are not confined to a pot-shaped ball.

Order in autumn for delivery in winter, and plant as soon as the ground is workable. Choose a mild, frost-free spell when the soil is not waterlogged. If your plants arrive before you are ready, heel them in — dig a shallow trench, lay the roots in it, cover with soil and firm gently. Never let the roots dry out; keep them in a damp sack or bucket of water while you work.

Whips of 60–90cm are ideal. They are cheaper, establish faster and will catch up with, and overtake, larger plants within a couple of seasons.

Ground preparation and planting day

Clear a strip about a metre wide along the hedge line. Perennial weeds such as couch grass and bindweed will out-compete young whips, so it pays to smother the strip with cardboard and a thick mulch the autumn before planting, or to dig the weeds out thoroughly.

Plant in a double, staggered row: rows about 40cm apart and plants 40cm apart within each row, giving roughly five plants per metre. This density looks thin at first but fills out fast and makes a hedge that is thick to the base.

• Dig a trench or individual holes deep enough to take the roots without bunching them.
• Plant to the same depth as the nursery mark on the stem — look for the darker line where the soil came up to.
• Firm the soil around the roots with your heel, then water well.
• Mulch 5–7cm deep with well-rotted compost or bark, keeping it clear of the stems.
• Fit spiral guards against rabbits and, on a windy site, consider a temporary windbreak.

Water through the first two summers if the weather turns dry. Once the roots are down, the hedge will look after itself.

Aftercare and a cutting regime that suits wildlife

Cut the new plants back by up to half straight after planting. It feels brutal, but it forces growth from the base and gives you a bushy hedge rather than a row of bare stems. For the next two or three years, trim lightly in late winter to encourage sideways growth.

After that, move to a rotation. Cut just one third of the hedge each year, on a three-year cycle, in late winter. That way there is always a section left to flower and fruit, and always somewhere for birds to nest. Never cut a hedge between March and August — that is peak nesting season, and active nests are legally protected.

Avoid flailing the top to the same height every year. It creates a dense outer shell with a hollow, lifeless middle. Let some sections run taller, leave the leaf litter at the base, and resist tidying the hedge bottom. The mess is where the wildlife lives.
