Why Early Spring Is Prime Time for Bare-Root Planting

There is a narrow, generous window in the British gardening year that opens somewhere around the middle of March and closes again by the end of April. The soil has drained after winter but still holds plenty of moisture, the air is cool enough that plants lose almost nothing through their leaves, and the roots have a fortnight or so of quiet growing weather before anything is asked of them above ground. If you have bare-root shrubs sitting heeled in against a hedge, this is the moment to get them into their permanent places.

Bare-root stock — lifted from nursery fields while fully dormant — is cheaper, lighter and far easier to establish than container-grown plants, provided the roots never dry out and the shrub goes in before it breaks into leaf. Once the buds open, the plant is spending energy it cannot yet replace. Plant now, while the soil is still cool and damp, and you give it the best possible start.

Choosing Native Shrubs for a Woodland Border

A woodland border works best when it mimics the structure of a real wood: taller trees at the back, a middle storey of shrubs, and low-growing plants knitting the ground together. Native species bring wildlife with them — caterpillars, berries, catkins and nesting cover — and they are forgiving of our climate.

• Hazel (Corylus avellana) — coppiced every few years for catkins and straight stems; excellent as a mid-layer shrub.
• Hawthorn — dense, thorny nesting cover, May blossom and autumn haws; good on heavy clay.
• Blackthorn — the earliest blossom, followed by sloes; suckers freely, so give it room.
• Guelder rose — lacecap white flowers, translucent red berries and brilliant autumn colour.
• Spindle — unfairly overlooked; pink-and-orange autumn foliage and curious four-lobed fruits.
• Dogwood — dark stems and black berries; happy in damper, shadier corners.
• Wild cherry and crab apple — blossom for pollinators, fruit for birds, and a light canopy to plant beneath.

Plant in loose drifts of three, five or seven of the same species rather than dotting them about singly. Woodland plants naturally grow in colonies, and drifts read far better in a border.

Planting Bare-Root Shrubs Properly

Unwrap the roots the day you intend to plant. If you cannot get them in straight away, heel them into a spare patch of soil and keep them damp. Before planting, stand the shrub in a bucket of water for an hour — no longer, or the fine roots will suffocate.

Dig a hole wide enough to take the roots spread out comfortably, roughly twice the spread of the root system, and deep enough that the old soil mark on the stem sits level with the surrounding ground. Break up the base and sides of the hole with a fork, particularly on clay. Work a couple of handfuls of leaf mould or garden compost into the backfill, but do not enrich it so heavily that the roots have no incentive to venture out.

Spread the roots over a small mound, backfill in stages, and shake the shrub gently so soil trickles between the roots. Firm with your heel in a circle around the stem — enough to close air pockets, not so hard that you compact the ground to concrete. Water generously, even if rain is forecast, and fit a rabbit guard or spiral guard where deer or rabbits are active. Trees and larger shrubs will want a short stake for their first two years; smaller shrubs usually manage without.

Mulching with Leaf Mould or Bark

Mulching is the single most useful thing you can do for a new woodland border. A layer of organic matter suppresses annual weeds, holds moisture in the root zone, keeps the soil temperature steadier and slowly feeds the soil life beneath it.

Leaf mould is the woodland mulch par excellence — soft, dark and full of the fungal life that trees and shrubs associate with. If you have none of your own, use a well-rotted bark mulch or composted woodchip instead. Aim for a layer 5–7cm deep, spread over a ring at least 1m across for a shrub and wider for a tree.

• Clear perennial weeds such as couch grass or ground elder before mulching — a mulch will not kill them, only hide them.
• Keep the material clear of the stem by a hand's width; piling mulch against bark encourages rot and invites voles.
• Water thoroughly first, then mulch. Mulching dry soil merely keeps it dry.
• Top up in autumn, and let the worms do the incorporation for you.

Watering and Weeding Through the First Season

For the first summer, treat new plantings as guests rather than residents. Water deeply once a week in dry spells — a full watering can per shrub, less often but properly, rather than a daily sprinkle. Hoe or hand-pull weeds before they set seed, and resist the temptation to feed with a high-nitrogen fertiliser, which pushes soft growth at the expense of roots.

By the following spring you should see strong new shoots and, in many species, the first tentative flowers. That is the sign that your woodland border has taken hold — and that the quiet work of a damp March morning has paid off.
