Pruning is essential to the health and aesthetics of beech hedges. When you prune correctly and at the right time, the hedge will look elegant, stay healthy and keep producing new foliage.
So, keep reading to find out how and when to cut a beech hedge. This little blog post will cover the basics of trimming, pruning and cutting beech hedges.
Understanding beech hedges
Beech hedges are stunning deciduous plants with dense, wavy foliage. Depending on the species, the leaves are usually lush green in summer. They start browning around autumn, developing shades of copper.
The foliage becomes brown during autumn. It remains this way throughout winter. Then, everything changes again as the growing season kicks off in spring. Throughout all of these, beech hedges remain elegant and visually appealing.
They are relatively fast-growing, too. Beech hedges can reach up to 10 metres tall and 5 metres wide. They grow at the rate of 30-60 cm per year.
These are why it’s so important to prune beech hedges. Pruning keeps the hedge’s size and shape under control, encourages new growth and discourages pests and diseases.
Remember, pruning technique and timing are crucial. So, let’s talk about when to cut a beech hedge.

When to cut a beech hedge
The right time to prune or cut a beech hedge is late summer. This gives the hedge enough time to recover before winter. By recover, we mean growing new foliage that will protect it from the winter cold.
So, late summer, especially around August, is the best time to cut a beech hedge. After this, you don’t have to prune it again until next summer. There are some exceptions. For example, if you want to keep a show hedge with a specific shape or size.
In this scenario, you can trim the beech hedge lightly in autumn. You can also trim off dead foliage and limbs in early spring or late winter. This kicks off the growing season by encouraging new growth.
Above all, you should avoid cutting a beech hedge between late March and late July. This is the nesting season for birds. Cutting the hedge during this period will disturb the birds, affecting the ecosystem of your garden. Besides, it’s illegal under the Wildlife and Countryside Act of 1981.
How to prune a beech hedge
Now that you know when to cut a beech hedge, let’s discuss how. The technique should depend on the condition of the hedge.
For a young beech hedge, you only need to trim the buds lightly to encourage branching and new growth. For established hedges, you need to prune annually. As for overgrown and old hedges, you have to renovate them over a period of 2 to 3 years.
Follow these steps and tips to trim or prune a beech hedge.
Step 1: Prepare your tools
Your cutting tools should include pruning saws, shears, secateurs and lopping shears. Sterilise them to avoid infecting the beech hedge(s) with diseases. You may also want some protective clothing like goggles, booths and gloves.

Step 2: Identify the limbs you want to cut
The primary targets are dead, damaged and diseased branches. Another set of targets is excess growths that affect the hedge’s shape, size and integrity. Finally, identify healthy branches that you can cut to encourage branching and new growth.

Step 3: Cut the beech hedge
Cut dead, damaged and diseased branches into healthy limbs. Cut the other branches that you marked earlier, too. You can use a string as a guide to help you make even cuts.
Use cutting tools that are sharp and sterile. They will allow you to make clean cuts and avoid infecting the beech hedge(s). Make your cuts from a 45-degree angle. Finally, let the base of the hedge(s) be wider than the top. This will ensure proper ventilation and supply of sunlight to the base.

Step 4: Dispose of the cuttings and clippings
This step is crucial, especially when dealing with diseased and pest-infested branches. If you don’t dispose of them properly, the disease could spread to healthy hedges and nearby plants.
So, get rid of those clippings and cuttings. You can burn, bury, compost or dump in a landfill.

Summary

Do these, monitor the hedge properly, and follow other maintenance tips. Then, your beech hedge should be healthy and visually appealing year-round.
