Woody prunings become garden structure: Build a small dead hedge
Existing woody prunings can become a small dead hedge between two rows of posts. Plan the structure, materials and wildlife safeguards without the tidying reflex.

An October idea: Existing woody prunings do not have to become a waste pile. A narrow dead hedge uses little material, but it needs a clear structure.
After an autumn tidy-up, twigs are often too bulky for the compost heap and too useful to discard. Loosely stacked between two rows of sturdy wooden posts, they form a dead hedge, sometimes called a Benjes-style hedge. It adds structure to the winter garden and lets the material age slowly where it is. One point matters from the start: this is not a reason to cut healthy shrubs for material. Use branches that have already resulted from an appropriate maintenance job.
Shorten only the awkward pieces
If an existing branch lying on the ground is too awkward for a safe build, a compact pull saw can bring the end to a manageable length. The FELCO 601 has a straight 120 mm blade, cuts on the pull stroke and is rated for a cutting capacity of up to 60 mm. Check the lock, your footing and eye protection first, and keep the supporting hand away from the cutting line.
Five steps to a small dead hedge
- Keep the footprint modest. A quiet strip of open ground is enough. Leave space from busy paths, play areas and open flames.
- Set two rows of posts. Untreated, stable posts form a narrow corridor. Width and height depend on the site and material; the finished structure must not tip.
- Fill loosely, not solidly. Lay branches and twigs lengthways between the posts. A mixture of thicknesses creates a stable structure without compressing it into a wall.
- Turn sharp ends inward. Nothing should project into a path or at eye level. Shorten awkward ends only when this is necessary for a safe build.
- Add to it over time. As the material settles and decays, suitable new prunings can be placed on top. That gradual change is part of the design.
What belongs—and what does not
Suitable: untreated twigs, slender branches and a few thicker pieces of wood from your own garden.
Keep out: painted or pressure-treated timber, plastic, wire, rubbish, material carrying problematic disease, and invasive plant parts that may regrow. Do not place thorny branches beside a path.
The calendar is not blanket permission to prune
Under Section 39 of Germany’s Federal Nature Conservation Act, the seasonal restriction on major work to hedges and shrubs applies from 1 March through 30 September inclusive; such work is generally possible again from 1 October. That does not mean every woody plant should be cut indiscriminately from October: year-round species protection under Section 44, occupied nests and resting sites, the correct pruning season for the species and additional local rules still matter. Inspect plants and existing prunings before any work. Do not move an occupied pile or dismantle it in winter. A dead hedge can be built from material that is already available; never remove wood from woodland, hedges or the wider countryside.
More structure, less tidying reflex
NABU and the Royal Horticultural Society recommend deadwood piles and dead hedges as ways to retain woody prunings in the garden. Material stacked between pairs of posts can be topped up as it settles. Whether—and which—animals actually use the structure depends on the site and its surroundings. It is an opportunity, not a guarantee.
Your 20-minute start: Choose the site today, sort existing branches by length and mark the two rows of posts. The build itself can follow at an unhurried pace.
