Hedge Cutting: When and How Often to Trim Your Hedges

8 August 2026

Well-kept hedges frame a garden and provide privacy, shelter and a home for wildlife. Timing your hedge cutting right keeps them healthy, dense and looking their best. Here’s our seasonal guide for gardens across Newtownabbey and beyond.

The best time to cut hedges

For most formal hedges, late spring to early autumn is ideal, once the main flush of growth is through. Fast growers like privet and leylandii often need two or three cuts a season, while slower hedges may only need one.

Watch out for nesting season

Between March and August, birds may be nesting in your hedge. It’s an offence to disturb active nests, so we always check before cutting during these months and time heavier work to avoid nesting periods where possible.

How often should you trim?

A light, regular trim keeps a hedge dense and easy to manage. Leaving it too long leads to woody, gappy growth that’s harder to bring back. For most gardens, one to three cuts a year does the job.

Bringing an overgrown hedge back

If a hedge has got out of hand, a hard reduction can usually bring it back under control, and we’ll shape it so it grows back neat and full. Very overgrown hedges may need staged work over a season or two.
