Introduction

Well-trimmed hedges can frame your garden beautifully, create privacy, and add a sense of structure to your outdoor space. But getting that crisp, professional look requires more than just running a trimmer over the top. It’s about knowing the right tools, the right technique, and — most importantly — the right time to trim.

In this guide, we’ll walk you through the seasonal approach to hedge trimming so you can keep them healthy, shapely, and thriving all year long.

Spring: Shaping for New Growth

Timing: Late spring, after the first flush of growth (April–May)
Spring is the time to encourage healthy regrowth while shaping hedges for the season ahead. We focus on removing dead or damaged branches, creating a strong outline, and allowing light and air to penetrate the plant. Avoid cutting too early, as frost can still damage fresh growth.

Summer: Keeping the Shape

Timing: Mid-summer tidy-up (June–August)
Warm weather means hedges grow faster, especially fast-growing varieties like privet and leylandii. This is the season for light, regular trims to maintain neatness without over-cutting. Frequent shaping also encourages denser foliage for a fuller appearance.

Autumn: Preparing for Dormancy

As temperatures drop, hedge growth slows, making this the ideal time for a more thorough trim before winter sets in. This helps maintain the shape and prevents overgrown, untidy branches from weighing down the plant.
