Planting Native Trees for a Resilient Landscape

Why native trees earn their place

A native tree is not simply one that grows here. It is one that evolved here, alongside our insects, fungi, birds and mammals, and that carries the local genetics to cope with our wind, wet and frost. An English oak may support more than two hundred species of moth and butterfly; a sycamore, useful as it is, supports a fraction of that. Plant native and you feed the whole chain — the caterpillars that raise the blue tits, the aphids that feed the ladybirds, the catkins and berries that carry birds through late winter.

There is a harder argument too. A landscape with a mix of species and ages is more resilient than one planted with a single tree. If disease, drought or a run of gales takes one species, the wood still stands.

Read the ground before you order a single tree

Most planting failures are decided long before the trees arrive. Spend an hour on the site first.

• Soil. Squeeze a handful of damp soil. If it rolls into a smooth ball that holds its shape, you have clay; if it crumbles and feels gritty, sand; if it is silky and slippery, silt. Clay holds water and nutrients but sits wet in winter; sand drains fast and dries out in August.
• Depth and drainage. Dig a spade-deep hole and fill it with water. If that water is still there in an hour, plan for alder, willow or aspen rather than beech.
• Lime. Chalk and limestone suit field maple, hawthorn, beech, yew and wild cherry. Acid ground favours birch, rowan, Scots pine and oak.
• Exposure. A windy western edge wants hawthorn, blackthorn and holly, planted densely enough to shelter what sits behind them. Tender species will be shredded.
• Frost pockets. Hollows where cold air pools favour late-flushing trees such as oak, beech and hornbeam, whose new growth avoids the worst of the spring frosts.

Species worth planting, and where

• Oak, field maple, wild cherry and crab apple: the backbone of a mixed wood on decent loam.
• Silver birch and rowan: quick, graceful and excellent on light acid soils or in a small garden.
• Alder and willow: wet ground and stream banks, where their roots hold soil together.
• Hawthorn, blackthorn, hazel and holly: the hedgerow and woodland-edge mix — nesting cover, blossom and autumn berries.
• Scots pine and yew: structure, winter colour and very long life where the site suits them.

Aim for a mix. Three or four species in a small copse, seven or eight in a field corner, and always some shrubby material along the edges.

Planting day: the details that decide survival

Bare-root whips, lifted while dormant and planted between November and late March, establish far better than potted stock and cost a fraction as much. Choose a mild, damp spell and avoid frozen or waterlogged ground.

Dig a hole wide enough for the roots to sit spread out comfortably, but no deeper than the tree's original soil mark. Tease out any circling roots. A sprinkle of mycorrhizal fungi over the roots helps them find water and nutrients in that first year. Refill in stages, firm with your heel, and check the tree does not rock. Water it in well, even in February.

• Stake only where exposure demands it. A short stake driven in at an angle, with a soft tie low on the trunk, lets the tree move and thicken. Remove the stake after three years.
• Guard against rabbits and deer. A spiral guard for whips; a taller mesh tube where deer browse.
• Mulch 5–7cm deep with well-rotted bark or compost, kept clear of the trunk. This is the single best investment you can make.

The first five summers

Grass and weeds are the great killers of young trees, taking water and light at exactly the moment the tree has least to spare. Keep a metre-wide circle clear around each one for at least three years.

In dry spells, give each tree ten to twenty litres a week — a slow soak, not a sprinkle. Check ties and guards every spring, and replace failures promptly; a ninety per cent survival rate after five years is a good result, and filling gaps early keeps the wood even.

Only light formative pruning is needed at this stage: take out a double leader or a badly crossing branch, and shape fruit trees in winter. Leave the rest alone to find its own form.

A wood is a long conversation

Think in decades rather than seasons. Plant quick growers such as birch, willow and alder as nurses, underplant oak and beech among them, then thin the nurses out once they have done their work. Coppice hazel on rotation, lay hedges as they thicken, and leave standing deadwood and a few fallen logs for beetles and fungi.

Keep a simple record — species, date, and where the stock came from — so that when someone asks in thirty years what is growing there, you can tell them. Then let the wood get on with it.
