When to Trim Your Hedges

Timing is key for hedge trimming & pruning. Different types of hedges have different growth cycles, so trimming at the right moment encourages healthy growth and prevents damage.

Spring and Early Summer

Most hedges benefit from a trim in late spring or early summer. This period follows the main growth spurt, allowing you to shape the hedge without cutting off new buds. For example, boxwood and privet hedges respond well to trimming in May or June.

Late Summer to Early Fall

A second trim in late summer or early fall helps maintain shape and control size before winter. Avoid trimming too late in the Autumn, as new growth may not harden off before cold weather, making the hedge vulnerable to frost damage.

Avoid Winter Trimming

Trimming hedges in winter can expose plants to cold damage and slow recovery. Most hedges enter dormancy during this time, so cutting can stress the plant and reduce its ability to survive harsh conditions.

Special Cases: Flowering Hedges

Flowering hedges like lilac or forsythia require careful timing. Trim these immediately after flowering to avoid cutting off next year’s buds. For example, prune lilacs in late spring right after they bloom.

How to Trim Your Hedges Properly

Proper technique ensures your hedges stay healthy and look their best. Follow these steps for effective trimming:

Tools You Need

• Hedge shears for small to medium hedges

• Electric or petrol hedge trimmers for larger or tougher hedges

• Pruning saw for thick branches

• Gloves and safety glasses for protection

  
  

Keep your tools sharp and clean to make smooth cuts and reduce the risk of disease.

Step-by-Step Trimming Process

1. Start with a clear shape in mind. Decide whether you want a formal, geometric look or a more natural shape.

2. Trim the sides first. Cut the sides slightly narrower at the top than the base. This shape allows sunlight to reach lower branches and prevents bare spots.

3. Shape the top last. Use a string line to keep the top even.

4. Remove dead or damaged branches. Cut these back to healthy wood to encourage new growth.

5. Avoid cutting into old wood. Many hedges do not regrow from old, leafless branches, so trim only where there is green growth.

   
   

Tips for Best Results

• Trim on a dry day to prevent disease spread.

• Work slowly and step back often to check your progress.

• Use light, frequent trims rather than heavy cuts to keep hedges healthy.

• Dispose of clippings properly to avoid pests and diseases.
