I would choose beech for its warm brown winter foliage on ground that drains freely. On heavier ground or a cold site, hornbeam is usually the more forgiving choice. Neither should be bought on the promise of an opaque evergreen screen: both are deciduous, and the leaves that remain through winter can vary.
They look similar enough in a nursery catalogue that price can become the deciding factor. Before comparing bundles, walk the proposed planting line after rain. A hedge runs through several metres of garden, and the low patch beside the gate may behave differently from the raised end near the house.
Choose for the ground first
Beech dislikes persistently wet roots. The RHS beech guide recommends hornbeam instead for very heavy or wet soil and frost pockets. That does not make hornbeam a plant for standing water: its RHS plant profile still specifies moist but well-drained or well-drained conditions.
I would not reject beech simply because a handful of soil feels clayey. The question is whether water moves away from the roots. Equally, a dry surface on the day you order does not prove that the site drains well in January. Look for persistent puddles, compacted access routes and water arriving from adjoining paving.
If part of the boundary remains saturated, investigate that section before committing to a uniform hedge. Replacing failed plants in the same wet pocket costs more than postponing the order while you resolve the planting position.
Decide how much winter cover you need
Clipped beech tends to retain more of its dead leaves than hornbeam. It changes from a green summer boundary to a copper-brown winter one. Hornbeam can retain some leaves too, but I would allow for a more open view through it. The RHS hedge-selection advice makes the same distinction.
Stand where privacy matters: the kitchen window, the patio chair or the pavement outside. A little filtered visibility may be perfectly acceptable along the end of a long garden. It can be disappointing when the hedge is meant to hide a seating area that you use all year.
If green cover all winter matters more than autumn colour, Portuguese laurel or common holly may fit the job better, depending on drainage, available space and the time you can allow for establishment. Beech and hornbeam remain the comparison here when you want a deciduous hedge; closer planting will not change their seasonal behaviour.
Both need room and regular clipping
These are trees managed as hedges. The eventual tree height on a label is not the height you must keep the hedge at, but neither species stays conveniently narrow without attention. Set the intended finished height and width before planting, including room to reach the far side.
A tall boundary you cannot comfortably maintain creates a recurring job or a recurring bill. I would rather keep the hedge within an accessible outline from the start than let it become a large screen and plan a heavy reduction later.
For a formal result, keep the base slightly broader than the top so the lower growth receives light. Ask for species-specific formative pruning advice with the order; sparse young plants and well-branched stock do not necessarily need the same first cut. Check for nesting birds before any trimming and postpone work wherever it would disturb an active nest.
Compare equivalent plants, not the first price shown
The green beech and hornbeam listings offer different sizes and root formats. Compare the same supplied height band and format, then check branching, quantities and delivery. A taller single stem is not automatically better screening than a shorter, bushier plant.
- Confirm the botanical name: Fagus sylvatica for common beech, Carpinus betulus for common hornbeam.
- Check whether the photograph shows the supplied plants or a mature hedge.
- Use spacing for that exact size and format; do not transfer the recommendation from a different pack.
- Compare the delivered cost for the whole run, with gates and deliberate gaps deducted.
For an autumn or winter order, choose a delivery period when you can receive and plant the stock. My guide to planting a hedge in winter covers ground conditions and getting the roots established. Keep watering and weed control in the budget; a cheaper bundle is poor value if it dries out while waiting for the ground to be ready.
On a free-draining site where I wanted a tidy brown screen in winter, I would buy beech. Where the soil is heavier or the position colder, I would lean towards hornbeam and accept the lighter winter cover.
