When Should You Cut Hedges? The Ultimate Seasonal Guide

Cutting your hedges at the right time is key to keeping them healthy, tidy, and long-lasting. Each hedge species has its own ideal trimming window. In this guide, we break down the best times to cut different hedges so you can enjoy lush, well-shaped growth every season.

The Golden Rule for Hedge Trimming

Most hedges grow vigorously from late March through September. Cutting at least once during this period keeps them in shape—though some fast-growers need more frequent trims. Always consider your hedge’s unique growth habits for the best results.

Season-by-Season Hedge Cutting Guide

Spring (March–May)

Spring is the perfect time for your hedge’s first cut—just wait until hard frosts are over.

• Deciduous hedges: Prune in early spring before leaves emerge—think beech, hornbeam, and hawthorn.
• Formal evergreens: Give box, privet, and yew their first tidy-up in late spring.
• Important: Always check for nesting birds before trimming. In the UK, disturbing active nests is illegal under the Wildlife and Countryside Act 1981.

Summer (June–August)

Summer is peak growth season—most hedges will need at least one trim to keep their shape.

• Fast growers: Privet, laurel, and leylandii may need two or three trims over summer to stay tidy.
• Flowering hedges: Trim spring-flowering types (like forsythia) right after blooms fade.
• Box: Cut in June and again in late summer if needed.
• Beech and hornbeam: Wait until August to trim, after their main flush of growth.

Autumn (September–November)

Autumn is the best time for your final trim, getting hedges ready for winter.

• Deciduous hedges: Give beech, hornbeam, and hawthorn their last cut in September.
• Conifers: Early autumn is ideal for a final tidy-up.
• Evergreens: Trim in early autumn to keep them neat through winter.

Winter (December–February)

Winter is usually not the best time for hedge cutting, but there are a few exceptions.

• Dormant deciduous hedges: Hard pruning or renovation is possible in January or February while plants are dormant.
• Avoid cutting: Most evergreens—frost can harm new cuts.
• Exception: Yew is tough enough for winter trimming if required.

Best Times to Cut Popular Hedge Types

Hedge Type	Best Time to Cut	Frequency
Privet	May to September	2-3 times per year
Beech	August to September	Once per year
Leylandii	April to August	2-3 times per year
Box	May and August	Twice per year
Laurel	June to August	1-2 times per year
Yew	August to September	Once per year
Hawthorn	July to September	Once per year

Expert Tips for Hedge Cutting Success

• Weather: Don’t trim during heatwaves, drought, or if frost is on the way.
• Sharp tools: Use sharp blades for neat, healthy cuts.
• Shape: Angle hedge sides so the base is wider than the top—this helps sunlight reach lower branches.
• Aftercare: Water after trimming in dry spells and mulch to lock in moisture.
• Take it slow: For overgrown hedges, spread heavy pruning over several years.

When Should You Call a Professional?

Most home gardeners can handle routine trimming, but sometimes it’s best to call in the pros:

• Very tall hedges that need special equipment
• Severely overgrown hedges needing restoration
• If you’re unsure about the best method for your hedge
• Hedges near power lines or hard-to-reach spots
