Planting bare-root hedging is a cost-effective way to establish a boundary, provided the plants are installed while dormant. Bare-root plants are lifted from the ground without a surrounding soil ball, making them lighter and generally cheaper than container-grown alternatives. Success depends on precise timing, correct planting depth, and consistent moisture during the first two years of establishment.

Timing and selection

Bare-root hedging is only available when plants are dormant, typically from mid-autumn to late winter. The specific window depends on the type of hedge:

Deciduous hedges: Species such as beech, hornbeam, and hawthorn should be planted from the time of leaf fall through to late winter.
Evergreen and semi-evergreen hedges: Bare-root stock must be planted in its dormant lifting season. Early-autumn advice for evergreen hedging generally concerns container-grown or suitable rootballed plants; follow the nursery’s instructions for the form supplied.

Planting must be delayed if the soil is frozen or waterlogged, as these conditions prevent the soil from being worked and can lead to root rot. If plants arrive before the ground is ready, they should be stored in a frost-free shed with roots covered in moist paper, straw, or potting compost. Alternatively, they can be “heeled-in” by planting them temporarily and closely together in a trench with roots fully covered in moist soil, without burying the stems deeply. Keep roots protected from drying wind while handling the plants.

Preparing the planting site

Proper soil preparation ensures that roots can penetrate the earth easily and access nutrients. Begin by digging over a strip 60–90cm wide to a depth of one spade blade (one spit). All weeds should be removed using non-chemical methods before planting begins.

For boundary hedges, the trench should be set back from the boundary line—for example, by 90cm—to allow the hedge to grow to its full width without overhanging a neighbour’s property or a public pavement.

Managing soil types:

Waterlogged soil: If the site is prone to winter flooding, a permanent drainage system may be necessary. A suitably raised planting ridge may help some sites, but it cannot make a persistently flooded site suitable for every hedge. Choose a species suited to the conditions and resolve drainage before planting.
Sandy or heavy clay soils: These benefit from the addition of organic matter. Improve the wider planting strip with well-rotted organic matter where needed; avoid filling a narrow trench with a rich compost pocket. Backfill mainly with the excavated soil and mulch the surface afterwards.

Crucially, do not place organic matter directly at the bottom of the planting trench; as it decomposes, it can cause the shrubs to sink.

Planting technique

Before planting, soak bare-root specimens in water for approximately 30 minutes to rehydrate the root system. Use a sharp knife or secateurs to trim any damaged roots back to healthy growth.

Spacing and layout:
Spacing varies based on the desired thickness and the vigour of the species. For a standard single row, plants are typically spaced 30–60cm apart. For a thicker hedge (over 90cm), use a staggered double row. For example, if planting a double row, the two rows could be 45cm apart, with individual plants spaced 90cm apart within each row.

Depth and installation:
1. Spread the roots out evenly in the trench.
2. Ensure the planting depth is correct: the point where the roots flare out from the stem should be level with the surrounding soil surface. Planting too deep can restrict air movement and increase disease risk.
3. Backfill with soil, working it carefully between the roots to eliminate air pockets.
4. Firm the soil gently with the heel of the boot to ensure close root-to-soil contact.
5. Water in after planting to settle soil around the roots, allowing excess to drain; do not plant into saturated ground.

Initial aftercare and establishment

The first two years are critical for hedge establishment. The primary goal is to prevent drought stress, as rain often fails to reach the root zone even when the surface appears damp.

Watering and weeding:
Keep the hedge well-watered during dry spells. In dry weather during the growing season, a general guideline for trees and shrubs is 30–50 litres of water per square metre each week, though this varies by soil type. Keep the hedge and a 45cm strip on either side free of weeds to prevent competition for nutrients and water.

Mulching:
Apply a mulch layer at least 5cm thick (up to 7.5cm) in late autumn or late winter. Materials such as well-rotted garden compost, chipped bark, or gravel help suppress weeds and retain soil moisture. When mulching, leave a small collar of about 10cm around the woody stems to prevent the bark from rotting.

Feeding:
Do not add fertiliser simply because the hedge is newly planted. Assess growth and soil in spring, and use an appropriate feed at its label rate if needed. If using a mycorrhizal product, follow its instructions; inoculants are optional and cannot replace suitable soil and watering.

Formative pruning and training

Pruning encourages the hedge to knit together and become dense rather than growing as a series of individual shrubs.

Formative pruning is species-specific. Hawthorn is often cut back firmly to encourage a dense base, whereas beech and hornbeam leaders are generally retained until the desired height is reached. Many conifer hedges also need their main leader preserved. Follow the nursery’s instructions for the named species rather than shortening all deciduous leaders by one-third.

Check for active bird nests before any trimming, at any time of year. March to August covers much of the nesting season, but birds can nest outside those dates. Leave a nest and surrounding cover undisturbed until breeding has finished; a quick check is not permission to trim close to an active nest.

Diagnosis of common problems

Newly planted hedges are more vulnerable to establishment issues than mature ones. Common signs of trouble include:

Dull, lifeless foliage: This is often a sign of drought stress. If the surface is moist but the plant looks stressed, dig down with a trowel to check if the root zone is dry.
Sinking plants: This usually occurs if too much organic matter was placed at the bottom of the planting hole.
Poor growth: This may be caused by planting too deeply or by competition from deep-rooted perennial weeds.

In exposed sites, young hedges may require temporary shelter for the first few years to protect them from wind damage.
