9 Hedging Whips from Hopes Grove for a 20-Metre Native Boundary

Nine whips across 20 metres is roughly one plant every 2.2 metres if you run them single-file. That gives you a thin, gappy line that takes six or seven years to knit. The standard Hopes Grove planting density for a stockproof native hedge is 5 to 7 whips per metre in a staggered double row, which for 20 metres means somewhere between 100 and 140 plants. So nine whips is a sample order, a trial run, or the start of a much bigger delivery. Worth knowing before you commit, because the price per whip drops sharply once you cross into the 250+ bundles.

If nine is genuinely all you want, treat them as feature plants. A single hazel (Corylus avellana) every 2 metres interplanted later with hawthorn, or nine whips used to gap up an existing run that has died back. Both are legitimate. Just do not expect a continuous screen from them in isolation.

Why bare-root whips beat pot-grown for a long run

Bare-root season runs roughly November to March, when the plants are dormant and lifted straight from the field. A 60-90cm hawthorn whip bare-root costs a fraction of the same plant in a 2-litre pot, and for 100-plus plants that gap is the difference between a £90 order and a £400 one. The roots establish faster too, because they have not spent a season circling a container.

The catch with bare-root is the window. Once the buds break in spring the whips are no longer liftable, and any supplier including Hopes Grove stops dispatching. Order in October for a December planting and you get first pick of the grades. Leave it to February and the popular species, field maple and hornbeam especially, start selling through.

When the bundle arrives, the roots will be in a plastic bag with a little damp packing. Get them in the ground within a day or two. If you cannot plant immediately, heel them in: dig a shallow trench, lay the whips at an angle, cover the roots with soil, firm down. They will sit happily like that for a fortnight. What kills bare-root stock is roots drying in wind or sun on the patio while you find your spade.

Spacing the staggered double row

Forget single file for anything you want to be stockproof or a real wildlife screen. The standard is a double row, 40cm between the two rows, plants 33cm apart within each row, offset so each whip sits in the gap of the row behind. That works out to six plants per metre.

For 20 metres at six per metre you need 120 whips. Drop to five per metre on a more open ornamental hedge and it is 100. Push to seven per metre for a dense formal hedge and it is 140. The nine whips in the headline cover about a metre and a half of proper double-row hedge. Useful as a test patch to check your soil and your species choices before scaling the order.

Mark the line with two canes and a string before planting. Lay all the whips out on the ground in their final positions first, mixing the species as you go so you do not end up with all the blackthorn at one end. A notched planting board or just a tape measure keeps the 33cm honest. Slit-planting with a spade is fine for whips this size: push the spade in, lever a gap, drop the roots, pull the spade out, firm with your heel. On clean ground a person can plant 100 whips in a long afternoon.

A native mix that actually feeds wildlife

A single-species hawthorn hedge is cheap and stockproof and fine. A mix earns its keep across more of the year. A typical Hopes Grove native conservation mix runs roughly 50 percent hawthorn (Crataegus monogyna) as the backbone, then hazel, blackthorn (Prunus spinosa), field maple (Acer campestre), dog rose (Rosa canina), and hornbeam or dogwood for autumn colour.

The wildlife logic is straightforward. Hawthorn and blackthorn flower in spring for early pollinators and set haws and sloes for autumn birds. Hazel gives you catkins in February and nuts that dormice and squirrels strip. Dog rose hips hang into winter. The companion planting idea that works inside a hedge is letting a climber, dog rose or honeysuckle, scramble through the structural shrubs so you stack two layers of flowering in the same metre.

Blackthorn is worth a word of warning. It suckers. Plant it near a lawn or a border and you will be pulling thorny shoots out of the grass for years. Keep it to the middle of a long rural boundary, not the bit next to your patio. The thorns themselves are vicious and the wounds go septic easily, so it earns its security reputation honestly.

Avoid an all-deciduous mix if you want winter screening. Slip in some holly (Ilex aquifolium) or a band of hornbeam, which holds its dead brown leaves through winter on a trimmed hedge. Ten to fifteen percent evergreen in the mix changes how the hedge reads in January.

North-facing boundary plants

A north-facing hedge line gets less direct sun, especially the lower third in winter. Hazel, hornbeam, holly, dogwood and dog rose all cope well in shade and a north aspect. Beech struggles more on heavy wet shade and field maple prefers a bit more warmth, so weight the mix toward the shade-tolerant species on that side.

First-year watering and mulch

The single biggest cause of bare-root failure is drought in the first summer, not winter cold. Whips planted in December sit dormant and barely need a drink until April. Then the buds break, the plant tries to push leaves with a root system that has not yet re-grown into the surrounding soil, and a dry May or June kills it.

Water deeply and infrequently rather than a daily splash. A full watering can per whip once a week in a dry spell beats a litre every day, because the deep soak pulls roots down. A 50-100mm mulch of bark or composted woodchip along the row holds moisture and smothers the grass that would otherwise outcompete the young roots for water. Keep the mulch a few centimetres clear of the stems so it does not rot the bark at the base.

Grass is the quiet killer. A whip with turf right up to its stem grows at half the rate of one in a 1-metre weed-free strip, because grass roots are ferocious competitors in the top 100mm where the young hedge feeds. A woven mulch mat or a sprayed-off strip before planting makes more difference to first-year growth than any feed you can buy. If you do feed, mycorrhizal root granules sprinkled into the planting slit do more for establishment than a top dressing of general fertiliser the roots cannot yet reach.

Rabbits and deer will browse fresh whips to the ground in a rural setting. Spiral guards on canes handle rabbits for a few pounds per plant. Deer need taller tube guards or netting, which for 120 plants becomes a real line on the budget, sometimes more than the whips themselves.

The first cut

Cut the leaders back by a third on planting, hawthorn and blackthorn especially. It feels brutal on a plant you just paid for. It forces low branching and is the difference between a dense hedge and a row of bare-legged stems with a tuft on top three years later.

When the order outgrows nine

The jump from a feature planting to a real boundary changes everything about the job: the price per whip, the staggered double row, the day of planting, the mulch budget, the guards. Nine whips you can carry home and plant in an hour. One hundred and twenty arrives as a heavy bundle of bare roots with a clock ticking on them. The question worth answering before you order is which of those two jobs you are actually starting, because the spacing maths gives very different answers, and the gappy middle ground of one whip every two metres is the one outcome nobody is happy with in year five.
