Beech hedging becomes a beautiful, bright green hedge in spring/summer and then in autumn/winter, it retains its medium sized leaves but they turn dry and copper coloured so it has two distinctly different appearances depending on the season. Beech hedging plants are classy when cut to a formal shape but it can also be used as a semi-evergreen component in a mixed native hedge. It will grow to 5m (or perhaps even more) but because it's just medium growth rate, it can be easily kept as a relatively low hedge - 1m upwards. It is a species that is really only suitable for free-draining soil - if your soil is wet/heavy clay, you should consider Hornbeam instead which has a very similar appearance but is better suited to wetter soils. Grows 30-60cm per year. Plants supplied 40cm+ high in 2 litre pots.
Potted Plants are a more developed plant as their root systems are not disturbed during the lifting and planting process. They can be planted year round and if necessary can be left in their pots for several weeks before planting if you are unsure as to when you will be able to get round to doing the work; all they need is a little water to keep them happy. As more mature plants you don’t need quite as many per metre as the bare root plants (normally 3 to 5 would suffice depending on how dense you require your hedge and how quickly you need it to look established). Pots are a great way to create a new hedge effect more quickly.
