Why a Hedge Earns Its Place

A hedge is the closest thing to a bargain in the garden. It marks your boundary, softens the wind, gives you something green to look at in the middle of January, and quietly feeds and shelters dozens of creatures you will probably never see. Unlike a fence, it grows more generous every year, and unlike a wall, it warms as the sun goes down, releasing the day's heat slowly into the evening.

If you have never planted anything woody before, a native mixed hedge is a forgiving place to start. Bare-root plants are cheap, they establish quickly in our damp winters, and a hedge is remarkably tolerant of being ignored now and then. Ten metres of hedgerow is a genuine contribution to your local wildlife corridor — a stepping stone between gardens, fields and verges.

Choosing Your Native Species

The secret of a good wildlife hedge is variety. Different plants flower and fruit at different times, so a mixed hedge offers food from February right through to the first hard frost. Aim for at least four or five species, repeating them along the row.

• Hawthorn — the backbone of any British hedge. Frothy white blossom in May, haws for thrushes and fieldfares in autumn, and dense, thorny growth that suits nesting birds perfectly.
• Blackthorn — the earliest blossom of the year, often before the leaves, which is a lifeline for newly emerged bees. Sloes ripen after the first frosts.
• Hazel — yellow catkins in February, plus nuts for squirrels, jays and dormice. Its leaves feed dozens of moth caterpillars.
• Field maple — a native tree that takes kindly to clipping and turns a buttery gold in October.
• Dog rose and guelder rose — flowers for insects in summer, hips and scarlet berries for birds in winter.
• Holly and beech or hornbeam — evergreens and leaf-holders that give shelter and cover when everything else is bare.

Order bare-root plants between November and March, ideally from a British-grown nursery, and plant them while they are still dormant.

Choosing the Spot and Preparing the Ground

Most native hedging will cope with anything from heavy clay to light sand, but almost none of it enjoys waterlogged roots or deep shade. A strip that gets sun for at least half the day will reward you best.

Before you plant, clear the ground of perennial weeds — couch grass and ground elder especially — along a strip at least 60cm wide. Dig it over to a spade's depth, working in a couple of buckets of well-rotted manure or garden compost per metre. Do not add fertiliser; rich soil makes soft, floppy growth that fails to harden before winter.

Check your boundaries first. A hedge can be kept to about 1.2 metres wide, but leave a good 45cm between the planting line and any fence or wall so you can still get a pair of shears behind it.

Planting Day, Step by Step

For a dense, wildlife-friendly hedge, plant a double staggered row — two lines 30cm apart, with the plants spaced 40cm within each line. That works out at roughly five plants per metre.

• Soak the roots for an hour while you dig.
• Set each plant so the soil mark on the stem sits level with the ground. Too deep is worse than too shallow.
• Firm the soil around the roots with your heel, then check by tugging gently — the plant should not move.
• Water well, even if rain is forecast.
• Mulch with 5–7cm of bark chippings, keeping it clear of the stems.
• Fit spiral guards where rabbits or deer are about.

If your soil is heavy and slow, a sprinkle of mycorrhizal fungi in the planting hole is a small kindness that helps roots find their feet.

The First Few Years

Water your hedge properly through its first two summers, giving it a thorough soak in dry spells rather than a daily flick of the hose. Keep a metre either side clear of grass and weeds, which compete fiercely for moisture.

After planting, cut the whole hedge back by about a third. It feels brutal, but it encourages bushy growth from the base rather than a few leggy stems. Trim again the following winter, and once a year after that. Never cut a hedge between 1 March and 31 August — that is peak nesting season, and it is also an offence to disturb a wild bird's nest.

For a truly wildlife-friendly hedge, cut it every second or third year, or trim only one side at a time, so there is always blossom and fruit somewhere along the row. Hawthorn and blackthorn flower on older wood, so a light hand means more haws and sloes next autumn.

The Slow Reward

Nothing about a hedge is instant, and that is rather the point. The first year it looks like a row of sticks; the second it thickens; by the fourth you will hear it before you see it — a small, busy rustle of sparrows, tits and the odd wren working the lower branches.

There is a particular comfort in a job that only asks a little of you each winter and gives back more every year. Plant it, water it, then leave it largely alone and let the seasons do the rest.
