Why native hedging earns its place

If you want privacy in a British garden, a fence goes up in a weekend and does its job from day one. What it will not do is feed a family of blue tits, shelter a hedgehog, or change with the seasons. A native hedge takes a few years to knit together, but once it does, it gives you a screen that is thicker, softer and far more interesting than any panel — and it asks for very little once it is established.

The trick is choosing the right species. Too many people plant a single row of leylandii or laurel and then spend the next twenty years fighting it. A mixed native hedge, built around hawthorn, hazel and blackthorn, grows dense from the base, tolerates a hard trim, and rewards you with blossom, berries, catkins and nesting cover. It is also, pound for pound, one of the cheapest ways to screen a boundary.

Hawthorn: the backbone of a British hedge

Hawthorn (Crataegus monogyna) is the traditional hedgerow tree of these islands, and for good reason. It establishes quickly, copes with wind, clay, chalk and even a bit of shade, and it knits into a thorny barrier that stock, dogs and footballs all struggle to get through. Plant it as the bulk of your mix — around 60 to 70 per cent of the total.

• Wildlife value: dense, low-branching growth makes it a favourite nesting site for blackbirds, dunnocks and robins, while the May blossom feeds early bees and the autumn haws sustain redwings and fieldfares through winter.
• Seasonal interest: frothy white flowers in May, deep red berries from September, and leaves that turn bronze before falling.
• Practical notes: thorny, so keep it back from paths and play areas. It responds well to cutting and can be laid if you fancy a traditional hedge.

Hazel: flexible, shade-tolerant and generous

Hazel (Corylus avellana) is the one to lean on if your boundary is partly shaded or you want a hedge that gives something back. It is happy in most soils, produces long yellow catkins in late winter when little else is happening, and crops of cobnuts in autumn if you get to them before the squirrels do. Make it roughly 20 per cent of the mix.

Because hazel regrows vigorously from the base, you can cut it hard without killing it. That makes it ideal for a hedge you plan to keep at a manageable height, or for a section you want to coppice every few years for pea sticks and bean poles. Its leaves also support a wide range of moths, which in turn feed bats and birds.

Blackthorn: early blossom and a sloe harvest

Blackthorn (Prunus spinosa) is the first hedge plant to flower, often while the branches are still bare in March. Those early blooms are a lifeline for emerging queen bumblebees. It is tough, thrives in poor ground and forms a dense, suckering thicket that is excellent for nesting birds — though that same suckering habit means you should not plant it where it can spread into a lawn you care about.

• Seasonal interest: white blossom before the leaves, followed by small oval leaves and then blue-black sloes in October.
• Uses: sloes make classic sloe gin, and the fruit feeds thrushes and winter migrants.
• Practical notes: the thorns are vicious, so site it along a boundary rather than beside a gate or path. Keep it to about 10 to 15 per cent of a mixed hedge.

Planting a mixed hedge that fills in fast

Bare-root plants go in between November and March, whenever the ground is not frozen or waterlogged. This is far cheaper than potted stock and establishes just as well, provided the roots never dry out.

• Prepare a strip, not individual holes: clear a metre-wide band of grass and weeds, then fork over the soil and work in a little well-rotted compost.
• Plant in a double, staggered row about 40 centimetres apart within the row and 45 centimetres between rows. This density is what gives you a solid screen rather than a line of gaps.
• Firm in well after planting so the roots have good contact with the soil, and water through the first two summers.
• Mulch with bark chippings or well-rotted manure to keep weeds down and moisture in.
• Add a few extras if you have room: field maple, guelder rose, dog rose or wild cherry all slot in nicely and increase the wildlife value.

Looking after it without endless work

The first cut matters more than any other. After planting, cut the whole hedge back to about 45 to 60 centimetres. It feels brutal, but it forces the plants to branch from the base instead of growing into bare-legged whips — the single biggest mistake with new native hedging.

After that, an annual trim is enough:

• Hawthorn: cut in late winter, before the birds nest. Aim for a slightly tapered shape, wider at the base, so light reaches the lower branches.
• Blackthorn: leave the trim until after the sloes have gone in autumn, otherwise you cut off the fruit and the winter larder.
• Hazel: cut on a three to five year rotation if you want catkins and nuts, taking a few stems rather than the whole plant.

Once a native hedge has thickened up, it needs perhaps one afternoon of work a year. In return you get a boundary that blocks sightlines, muffles road noise, shelters your garden from wind, and quietly fills with birds, bees and moths. Few things you plant will work harder for the space they take.
