How & When to Trim Your Hedges

Thursday 1st August 2019



The time of year in which you choose to trim your hedges plays a large role in not just how they look for the rest of the year, but how healthy they are, and how well they grow the following year. 

That's why we've put together this handy guide to tell you the best practices for some of the most common types of hedges.

Yew should be trimmed once a year in August or September. Prune it back hard in April if it's getting too large.  You can manage a large hedge by trimming it right back to the main trunk. Trim back the top in year one, then one side of the hedge in the year two before finally trimming the other side in the third year. This means the hedge always has a good amount of green leaves to fuel the plant as it regrows. Remember to give the hedge a granular, slow release feed to help it put on good growth. 




These should be trimmed up to three times a year: April, July and late August. This hedge is fast growing and you can't cut back beyond the green growth, or the plant won't recover and it will leave bare patches. Little and often is the best way to keep it under control. 




Beech and hornbeam hedges can be pruned in August. They grow quickly in the earlier part of the year, but need to grow a bit after cutting to make sure there's no bare patches through the winter. If the hedges have grown too large, trim back hard in mid-winter, avoiding very cold spells. 




Privet should be trimmed at least twice a year, from May to August. The more you trim it, the more it forms a thick, even hedge and the easier it is to maintain it at the size you want. If required, prune it hard in April to keep the size down.. 




Cut your Laurel hedges in either July or August. This plant has large, tough leaves, and hedge trimmers can leave them looking ragged. Remove any damaged leaves with secateurs to keep the hedge healthy and attractive. Trim back hard in spring to reshape overgrown hedges. 




Hawthorn flowers in May, so trim it after flowering in June. If you want to have a dense, formal hedge then trim again in autumn, but you'll probably have far fewer flowers. Alternatively, trim every few years and leave the berries for the birds to feed on if you like an informal hedge. To reduce a large hedge, cut back hard in winter. 




Holly should be cut once a year in late summer. If it's overgrown, cut back hard in spring. 




Berberis should be cut back after it has flowered. It can be trimmed into a dense, formal hedge. If you prefer an informal hedge with berries, cut back every few years to stop it getting too big




Escallonia can be trimmed in May and again in late August if you want a formal hedge without flowers. For an informal, flowering hedge, cut after flowering in June. Hard prune in the spring to reduce its size.
