Description
Instant Hornbeam Hedging & Troughs: Carpinus betulus
Hornbeam is probably the most popular deciduous hedging plant in the country for shadier and damper sites where beech won't grow: they are very similar looking.
It is extremely tough and easy to grow. Many times down the years, we've heard from people who didn't water a garden's worth of new plants in Summer, and most of them died ... except the Hornbeam!

Its leaves are the most brilliant of greens in spring; Monty Don says that the colour makes his "eyes dance". The veins on each leaf are separated by a corrugated trough so that the leaf with its serrated edge looks a bit crinkled which gives the hedge an interesting texture. The trunks and bark of hornbeam are always well shaped and slightly ridged. In the autumn (unless it has been exceptionally dry) the leaves turn a clear yellow before becoming pale brown for the winter.

Growing Hornbeam
Hornbeam will thrive in almost all soils, unless it is completely waterlogged all year, but prefers a well-drained rich soil. It will grow more slowly and a bit less luxuriantly, but happy nonetheless, in close to full shade. In open, sunny conditions, it is fast-growing.
Just like with beech, if you trim the hedge in mid-summer, the winter leaves will be 'everciduous', meaning that they stay on the branches until next spring.
Planting Instructions
Growing Hornbeam plants:
Hornbeam will grow well in any averagely fertile conditions, including chalky places. It loves damp clay soil and it will grow well in quite deep shade. It is very hardy when it is dormant in winter, but in the wild, it doesn't grow at high altitude in Northern regions where late spring and early winter frosts are more severe. Nor will it grow well if the soil is very poor and dry.
Watch our video on how to plant a formal hedge for full details. The plants in this video are delivered pot-grown, but planting out bareroot stock is essentially the same.
After you plant a hedge, the most important thing to do is water it in dry weather. If you didn't use a mulch of some kind, you will also need to weed around the hedge. Both of these will be necessary for at least a year after planting.
Trimming Formal hedge plants:
Hornbeam doesn't need any clipping at all in its first year. From the second winter onwards, your young hedge should be trimmed lightly once a year, until it is mature. When it is fully grown, the ideal time to clip it is in August. This will make the hedge hold onto its autumn leaves for longer during winter.
Special notes on caring for Hornbeam hedges:
Hornbeam is a very tough hedge plant that shouldn't need special attention once it has established, except that we advise you not to carry out major pruning work in late spring. It will "bleed" sap, which isn't a major problem but it is better to avoid it.
If you didn't use a mulch fabric, it is beneficial to mulch around the base of the hedge each year with well-rotted manure or compost.
Hygiene & Diseases:
Dead, damaged or diseased wood can be pruned off as soon as it appears. Disinfect your pruning tools between every cut if there is any sign of disease.
Burn or dispose of any diseased material, do not compost it.
Did You Know?
It has been a highly valued tree for many years because its timber is the hardest grown in this country. There is a venerable tradition of hornbeam being used to create butcher's chopping blocks, piano hammers and pulley blocks. It was often grown as wood 'pasture', leaving room for cattle to graze around the pollarded trees, which were pruned every few years for firewood and small objects like handles. The density is excellent for firewood and for making charcoal.
To see hornbeam at its most splendid, take a trip to Het Loo in Holland to see the Queen's garden, a labyrinth of covered walkways, caves and tunnels all fashioned from hornbeam grown over an oak trellis.
The best example of a pleached hornbeam hedge can be seen at Hidcote Gardens.
