Why a native hedge beats a panel fence

A close-boarded fence goes up in a weekend, but it never gets any better than the day you built it. A native hedge starts as a row of bare sticks and spends the next twenty years improving: thickening at the base, filling in the gaps, muffling traffic noise, and quietly becoming the busiest wildlife corridor on your plot. It also filters wind rather than blocking it, which means it stays upright in a gale and doesn't funnel gusts into your neighbour's garden.

If privacy is the goal, you need density. That means the right species, the right spacing, and planting at the right time of year — which is autumn, without exception.

The three workhorses: hawthorn, blackthorn and hazel

You can build a superb boundary from just three natives. They knit together at different heights and flower at different times, which keeps the hedge useful to insects and birds from February through to November.

• Hawthorn (Crataegus monogyna) — the backbone of almost every traditional British hedge. Thorny, fast, and tolerant of clay, wind and salt. Expect 30–60cm of growth a year on decent soil. Creamy May blossom, then red haws that feed redwings and fieldfares in winter.
• Blackthorn (Prunus spinosa) — the earliest blossom of the three, a froth of white on bare black twigs in March. It suckers freely, which is exactly what you want at ground level: a genuinely impenetrable thicket where a fence would leave a gap. Sloes follow in autumn if you fancy gin.
• Hazel (Corylus avellana) — lambs' tail catkins in late winter, nuts in September, and handsome pleated leaves. It copes with a bit of shade and responds well to hard cutting, so it adds structure and longevity to the mix.

A workable ratio is roughly 60 per cent hawthorn, 20 per cent blackthorn, 20 per cent hazel. If you want more variety, slip in the odd field maple, guelder rose or dog rose — but keep the thorny species dominant, because they are what makes the hedge stock-proof and private.

Getting the planting right in autumn

Buy bare-root whips rather than container-grown plants. They are cheaper, establish faster, and the season runs from November to March while the plants are dormant. Aim for November to early December if you can — the roots get a head start before the soil goes cold. Never plant into frozen or waterlogged ground, and if your whips arrive before you are ready, heel them into a spare patch of soil so the roots don't dry out.

For a genuinely dense screen, plant a double staggered row: about 40cm between the rows and 45cm between plants within a row, which works out at roughly five whips per metre. A single row at 30cm spacing will do for a thinner boundary, but it will never be as solid.

• Clear perennial weeds first — couch and bindweed will smother young whips.
• Dig a trench, fork the base to break up compaction, and work in well-rotted organic matter.
• Soak the roots for an hour before planting, and set the whips at the same depth as the soil stain on the stem.
• Firm in with your heel, then cut each whip back by about a third to encourage bushy growth from the base.
• Fit spiral guards against rabbits and mulch around the plants, keeping the mulch clear of the stems.

Looking after the first two years

Weeding matters far more than feeding in the early years. A whip competing with grass will sit still for two seasons. Water thoroughly in dry spells — one slow, deep soak a week beats a daily flick of the hose — and keep the ground around the base clear for the first two summers.

Resist the urge to trim the top during this period. Let the leaders run up towards your target height, which for privacy is usually somewhere between 1.8m and 2.5m. A double row planted at the spacing above will start to feel like a real screen in four or five years, and will be properly dense by year seven.

Trimming with birds in mind

Nesting season runs roughly from March to August, and under the Wildlife and Countryside Act 1981 it is an offence to damage or destroy a nest that is in use. So leave the hedge alone through spring and summer, and do your cutting in late September or October once the young have flown. A mild, dry day in winter works too — just avoid frost, which can shatter cut stems.

Cut the sides before the top, and taper the hedge so the base is wider than the crown. That A-shaped profile lets light reach the bottom, keeping it thick low down where you actually need the privacy. In the first few years, just tip the sides back lightly; once the hedge has reached the height you want, start cutting the top to that line.

Leave the haws, sloes and hazelnuts standing through the winter. They cost you nothing and they are the whole point of planting native in the first place.
