Planting Bare Root Trees And Shrubs In Winter

Winter might feel like a fallow period in the garden, but for bare root trees and shrubs it is the golden window. Between leaf fall and bud burst, woody plants are dormant above ground while their roots remain quietly active in the soil. Planting now gives them months to settle in before spring asks anything of them, and it is kinder on your wallet too. Whether you dream of a native hedgerow, a community orchard or a single crab apple for the birds, bare root planting is one of the most rewarding winter jobs you can do.

Why winter is the best time for bare root planting

Bare root plants are lifted from the field while dormant, so they travel with no soil around their roots. This sounds brutal, but it is actually ideal. The shock of transplanting is minimal because the plant is not trying to grow leaves or flowers. Instead, it focuses on root growth in the cool, moist soil that UK winters usually provide.

• Roots establish early: new roots can grow whenever soil temperature is above about 4°C, long before top growth begins.
• Better value: bare root is far cheaper than containerised stock, so you can plant a hedge or small copse for the price of a few pots.
• Wider choice: specialist nurseries offer native and heritage varieties that rarely appear in garden centres.
• Less watering: winter rain does most of the work, though you must still check in dry, cold spells.

The window runs from November to late March, but earlier is better in most of the UK. Aim to plant before Christmas if you can, so roots have the longest possible time to anchor themselves.

Choosing frost-tolerant natives for UK gardens

Our native trees and shrubs are fully hardy and have evolved alongside our wildlife. They shrug off frost, tolerate wind and often thrive in poor soil. For a hedgerow that feeds birds and insects, consider hawthorn, blackthorn, hazel, field maple, hornbeam, rowan, crab apple, guelder rose and dog rose. These are all frost-tolerant and will cope with exposed sites once established.

Match the plant to your soil. Hawthorn and field maple are adaptable, but hornbeam prefers heavier clay, while rowan and crab apple like well-drained ground. Blackthorn suckers freely, so give it room. If you have a wet corner, alder or willow will thrive, though they are less tolerant of drought later. For small gardens, choose compact varieties or keep a single specimen tree such as a native crab apple, which offers blossom, fruit and autumn colour in one tidy package.

Preparing the ground and planting correctly

Good preparation makes all the difference. Clear perennial weeds such as couch grass and nettles before you plant, as they will compete fiercely for water and nutrients. Dig the area over lightly, but do not add rich fertiliser; bare root plants prefer a modest start.

• Soak the roots: stand bare root plants in a bucket of water for 30 minutes before planting, but never leave them soaking for hours.
• Dig a wide hole: make it wider than the spread of the roots, and no deeper than the soil mark on the stem.
• Spread the roots: fan them out over a small mound of soil, then backfill gently, firming in layers to remove air pockets.
• Stake if needed: trees in exposed sites benefit from a short stake and a soft tie that allows some movement.
• Mulch well: apply a 5–7cm layer of well-rotted compost or bark, keeping it clear of the stem.
• Water in: even in winter, a thorough soak after planting settles the soil around the roots.

For hedges, plant in a double, staggered row about 30–45cm apart. This creates a dense barrier that wildlife will use as a corridor and shelter.

Caring for new plantings through frost and thaw

Winter aftercare is mostly about monitoring. Check plants weekly during dry, cold spells and water if the soil is dry below the surface. On heavy clay, avoid planting into a waterlogged hole; instead, plant on a slight mound so excess water drains away from the roots.

Frost heave can lift newly planted shrubs as the soil freezes and thaws. If you see roots exposed, gently firm the plant back in. After gales, check stakes and ties, loosening any that have become tight. Do not feed until spring, when new growth appears. A light mulch in late winter will conserve moisture and suppress weeds, but keep it away from the bark to prevent rot.

Planting for wildlife: hedges, berries and shelter

A mixed native hedge is one of the best investments you can make for UK wildlife. Frost-tolerant and long-lived, it offers berries for thrushes and blackbirds, catkins for early bees, and dense twiggy growth for nesting sparrows and finches. Hazel provides nuts for mice and squirrels, while guelder rose and dog rose give autumn colour and hips for birds.

Leave some sections untrimmed through winter so insects and small mammals have somewhere to hide. Even a short run of native shrubs in a small garden will bring in more birds and pollinators than a single exotic specimen. Plant bare root whips in winter and they will knit together within three or four years, creating a living fence that needs little watering once established.

Seasonal pitfalls and final tips

Never plant into frozen or waterlogged ground; wait for a milder, drier spell. Protect young trees from rabbits and deer with spiral guards or a temporary fence, as winter bark is a favourite food. Keep grass and weeds at least 60cm away from trunks for the first two years. Prune only to remove damaged branches at planting time, and leave formal shaping until the following winter.

Remember the old saying: first year they sleep, second year they creep, third year they leap. Bare root planting is an act of patience, but the rewards—a frost-hardy hedge, a blossom-laden tree, a garden alive with birds—are worth every cold-fingered morning.
