Why a well-kept hedge earns its keep

A hedgerow on a smallholding is never just a line of bushes. It is a stockproof boundary, a windbreak that shelters ewes and lambs, a corridor for wildlife moving between fields, and a slow-growing supply of stakes, binders and firewood. Get the maintenance right and all four jobs happen at once; let it slide and you end up with a gappy, leggy hedge that neither holds sheep nor looks like it belongs in the landscape.

Roughly half of Britain's hedgerows have disappeared since the 1950s, mostly through removal and neglect, so what you do with your own boundaries genuinely matters. A hedge in good heart is thick at the base, dense through the middle, and full of hips, haws and nests by late summer.

The wildlife calendar: when to cut, and when to leave well alone

Timing is the single biggest decision you will make each year. Under the Wildlife and Countryside Act 1981 it is an offence to damage or destroy the nest of any wild bird while it is in use, and for most hedgerow species that means roughly 1 March to 31 August. Treat those dates as immovable unless you have had a proper look and are certain nothing is nesting.

Beyond the legal minimum, think about food. Hawthorn, blackthorn, holly and dog rose carry berries that feed redwings, fieldfares and blackcaps well into winter, and the hips and haws are also stripped by small mammals. Cutting in September or October throws that larder away.

• Ideal window: late November to the end of February, once the berries have gone and the leaves have dropped.
• Avoid: hard frost, when cuts shatter and disease gets in, and waterlogged ground that will poach under machinery.
• Rotation: cut no more than a third of your hedges in any one year. The uncut stretches give birds, hedgehogs and invertebrates somewhere to sit while the rest is trimmed.
• Height: aim for 2 to 2.5 metres where space allows. Taller, thicker hedges shelter stock far better than a low, tight one.

Tools and technique for a tidy but living hedge

For awkward corners a brushcutter and a decent pair of loppers will do, but for long runs a tractor-mounted flail or a reach mower saves days. Whatever you use, keep the blades sharp and run the engine at full revs so the cut is clean rather than bruised.

The shape matters as much as the timing. Cut to an A-profile — wide at the base, narrower at the top. Light reaches the bottom of the hedge, so you keep growth down there instead of a bare, gap-toothed skirt of stems, and the sloped face sheds snow and deflects wind upwards over your stock.

Try not to cut back to the identical line year after year. Repeated trimming at the same point builds up a knuckle of dead wood and hollows out the middle. Vary your cut by a few centimetres and let the hedge breathe.

Laying and rejuvenating a tired hedge

If your hedge is all trunk and no bottom, flailing alone will not fix it. Laying is the traditional answer, and on a smallholding it is one of the most satisfying jobs you can do with a billhook and a chainsaw.

Pleaching means cutting each stem part-way through near the base — leaving a hinge of living wood — and folding it over at roughly 30 to 45 degrees. The pleachers are held down with stakes and woven binders, usually hazel. New growth shoots from the cut base, and the laid stems thicken into a living fence that will hold cattle. Most hedges benefit from laying on a 15 to 25-year cycle, with one stretch tackled each winter.

For gaps and new plantings:

• Plant bare-root whips between November and March, when the ground is workable and the plants are dormant.
• Use a double, staggered row — roughly five to six whips per metre — with a native mix of hawthorn, blackthorn, hazel, field maple, dog rose and guelder rose.
• Fit spiral guards against rabbits and voles, and mulch with well-rotted manure or bark to keep the grass down for the first two seasons.
• Water through the first dry summer; after that, native whips look after themselves.

Boundaries, stock and the rules worth knowing

In England and Wales, the Hedgerows Regulations 1997 mean you need permission from the local planning authority before removing most countryside hedges, particularly older, species-rich ones. Scotland has its own arrangements, so check with your local authority before taking anything out.

The old convention on ownership is that you own the hedge and ditch on your left as you stand at the boundary facing away from your property — useful when a neighbour disputes who should be cutting. You may trim back branches overhanging your land, but you must offer the cuttings to the owner rather than simply tipping them over the fence.

Where a hedge runs alongside a public highway, keep growth clear of the carriageway and footway. The Highways Act 1980 gives local authorities powers to require clearance, and obstructing a road or path is never worth the argument.

A year-round routine that keeps on top of the job

Walk your boundaries properly four times a year rather than glancing at them from the tractor cab.

• Spring: check guards and stakes after winter gales, and note any gaps to plant next season.
• Summer: keep an eye out for nesting birds, and top tall growth only if it is genuinely obstructing a gateway or right of way.
• Autumn: repair fences, clear ditches, and work out which third of the hedges is due for cutting.
• Winter: cut, lay, plant and Coppice hazel stools on rotation.

Do that much and you will have boundaries that hold stock, shelter your fields, and hum with life from March onwards — which is exactly what a rural smallholding should look like.
