How to Build a Stumpery for Shade

A stumpery is a shady garden feature made from tree stumps, roots and logs, planted with ferns and woodland plants. It turns a dark, awkward corner into something you’ll want to show off. The stumps often go in roots-upward, so the twisted roots look like sculpture.

The idea is Victorian. One of the earliest stumperies was made at Biddulph Grange in Staffordshire in the 1850s, now looked after by the National Trust. You don’t need a country estate, though. Three or four stumps and a few ferns will do it. This guide covers finding the wood, building it safely, planting it up and keeping it going.

Why a stumpery suits a shady, damp corner

A stumpery is made for the bit of garden where nothing else does well. That’s usually on the north or east side, under trees or against a fence, where light is thin and the soil is either dry or slow to drain.

Grass struggles there and bedding sulks. Stumps and ferns, on the other hand, look at home. Part-buried wood holds moisture in dry shade. In wet shade it lifts plants above soggy ground. As the wood slowly rots, it adds organic matter and builds the dark, crumbly soil woodland plants love.

Size is flexible. A small garden needs only three or four stumps, tucked against a shady wall. A bigger plot can have a whole walk lined with roots. Either way, keep the wood in scale so it looks planned, not like a pile you forgot to clear. If you’re still working out which parts of your plot get sun, our guide to reading your garden’s aspect and light helps you find the shadiest spot.

Three stumps and a skirt of ferns are enough to make a shady corner into a feature, even in a small town garden.

Where to find free stumps, roots and logs

Good stumpery wood is often free. Tree surgeons regularly remove stumps and root-balls, and some are happy to drop them off rather than haul them away. Ring a few local firms and ask them to keep back interesting roots from their next job.

Your own felled or storm-damaged trees are ideal. Firewood merchants sometimes have large butts and root pieces. If you spot wood on a verge or building site, always ask before taking any.

Aim for a mix of sizes. A few big root-balls give you the backbone. Smaller stumps and logs build up the levels around them. Roots with plenty of twists and hollows make the best upturned pieces.

Never use anything painted, treated, oiled or creosoted. That rules out old fence posts, decking offcuts and most reclaimed sleepers. Preservatives leach into the soil and harm the very wildlife a stumpery is meant to shelter. If you can’t be sure the wood is untreated, leave it out.

Freshly dug root-balls like these are the backbone of a stumpery. Ask a local tree surgeon to keep some back for you.

Which wood lasts longest in a stumpery?

Hardwoods last longest. Oak and sweet chestnut rot slowly, so they give the stumpery its lasting shape. Softwoods such as pine and spruce break down within a few years.

Neither is wrong. Slow-rotting wood gives you structure. Fast-rotting wood feeds the soil and the beetles sooner. A mix of both works well, with hardwoods for the big pieces and softwood logs to fill in.

How to build a stumpery step by step

The build needs no cement, no membrane and no power tools. A spade, a wheelbarrow and a strong helper will do. Autumn to early spring is the best time, when the ground is workable and you can plant straight after.

1. Pick the site. Choose a shady, sheltered spot, such as a north or east-facing corner, under trees or against a wall. Clear it of turf and perennial weeds.
2. Set the biggest pieces. Place the large root-balls first, roots-upward, so the best side faces where you’ll look from. Work from the back forward, tallest to shortest.
3. Part-bury each base. Dig each stump in 20-30cm deep and firm the soil hard around it. Heavy stumps can crush fingers and toes, so wear gloves and boots and lift with a helper.
4. Build the levels. Lean smaller stumps and logs against the big pieces so they lock together. Aim for hollows, ledges and planting pockets, not a flat heap.
5. Fill the gaps. Pack the spaces with a mix of leafmould, garden compost and topsoil. Firm it into every crevice so there are no air pockets.
6. Plant the pockets. Set ferns and shade plants into the filled gaps at the same depth as their pots. Water each one well.
7. Mulch. Cover bare soil with 5cm of leafmould or leaf litter. Water the whole feature and let it settle over the first year.

Before planting, give dry stumps a good soak with the hose. Very dry wood soaks up water from the soil around it, so wetting it first helps new plants settle.

Set the big root-balls first and bury their bases 20-30cm deep. Firm the soil hard so nothing can wobble once you start planting.

The best ferns and plants for a stumpery

Ferns are the heart of a stumpery, just as the Victorians intended. Set them in the pockets and let the fronds arch over the roots. Around them, add broad-leaved woodland plants to carpet the ground.

Match each plant to its light and moisture. Our guide to the best plants for dry shade covers spots where tree roots take all the water. For more fern choices, see the hardy UK fern guide.

Hostas love the damper pockets, though slugs love them too. Our guide to growing hostas has ways to keep them looking good. Hellebores bring flowers in late winter when little else is out.

For quick cover in smaller crevices, add tiarella, sweet woodruff, foxgloves and ivy. Foxgloves are poisonous if eaten, so skip them if small children or pets like to chew plants. Moss usually arrives by itself within a season or two. Leave it be, as it makes the wood look ancient.

How a stumpery helps garden wildlife

Rotting wood is one of the best wildlife homes you can give a garden. As the stumps break down, beetle larvae, woodlice and fungi move in. Toads, frogs and hedgehogs shelter in the damp gaps.

In southern England, buried rotting wood can help stag beetles. Their larvae feed underground for several years before the adults appear. Further north, other beetles use the same wood. If wildlife is your main aim, a simpler wildlife log pile does a similar job in a fraction of the space.

The golden rule is to leave things alone. Don’t tidy the crevices, and leave fallen leaves where they land.

Beetle larvae and a toad sheltering in soft, rotting wood. This is why it pays to leave a stumpery untidy.

Stumpery care through the year

A stumpery is low-maintenance, not no-maintenance. The jobs are light and seasonal.

Snip off last year’s tatty fronds in March, before the new ones uncurl. It keeps the stumpery fresh without disturbing wildlife.

You’ll need plenty of leafmould for filling and mulching. Our guide to making leaf mould shows how to turn this autumn’s leaves into next year’s supply.

Common stumpery mistakes to avoid

• Picking a sunny spot. Full sun scorches ferns and dries the wood out. A stumpery needs shade and shelter.
• Not burying the stumps. Stumps sitting on the surface lean and can topple, especially once children or dogs climb on them. Bury every base 20-30cm deep.
• Skipping the leafmould. Bare gaps between stumps grow nothing. Fill every pocket with leafmould and compost before you plant.
• Planting sun-lovers. Lavender, sedums and most grasses flop and rot in shade. Stick to ferns and woodland plants.
• Using treated timber. Old posts and sleepers often carry preservatives that harm wildlife. Use clean, untreated wood only.

Give it a few years and moss covers the wood while the ferns knit together. The whole corner starts to look like an old wood.

Frequently asked questions

What is a stumpery in a garden?

A stumpery is a shady feature built from tree stumps, roots and logs. The stumps often sit roots-upward so the twisted roots show. Ferns, mosses and other shade-lovers grow in the gaps. The idea is Victorian, and one of the earliest was made at Biddulph Grange in Staffordshire in the 1850s.

Where do I get stumps for a stumpery?

Ask local tree surgeons, who often have stumps and root-balls to get rid of. Your own felled or storm-damaged trees are ideal too. Firewood merchants sometimes have large butts. Always ask before taking wood from a verge or site, and never use treated or painted timber.

How deep do you bury stumpery stumps?

Bury each base 20-30cm below the soil. This anchors the stump so it cannot shift or topple. The buried wood also stays damp and starts to rot from below, which helps fungi and beetles. Firm the soil hard around each one.

What plants grow best in a stumpery?

Ferns are the classic choice, with hostas, hellebores and epimediums around them. Wood anemones, sweet woodruff and tiarella fill smaller gaps, and moss soon arrives on its own. Pick plants for your light. Dry shade under trees suits epimediums and male fern, damp shade suits hostas and hart’s tongue fern.

How long does a stumpery last?

Hardwood stumps such as oak last many years before they collapse. Softwoods like pine rot much faster, often within a few years. You never need to rebuild all at once. Slot in fresh stumps as older ones break down and the feature keeps going.

Can you build a stumpery in a small garden?

Yes, three or four stumps are enough for a small stumpery. Tuck it into a shady corner, against a north wall or under a single tree. One raised root-ball with ferns around it works in a courtyard. Keep the stumps in scale with the space.

Is a stumpery good for wildlife?

Yes, rotting wood is a valuable home for wildlife. Beetle larvae, woodlice and fungi feed on it, and toads, frogs and hedgehogs shelter in the gaps. In southern England it can help stag beetles, whose larvae feed on buried rotting wood for several years.
