When and How Often Should You Trim Hedges? A Seasonal Pruning Calendar

Hedges play a big part in keeping your garden neat and beautiful. They create natural boundaries, add greenery, and even protect your privacy. But to keep them healthy and tidy, regular trimming is important. Many Sydney homeowners are unsure about when and how often to trim their hedges, so in this guide, we’ll explain it season by season.

If you’re looking for simple, expert-backed advice on hedging and pruning Sydney, this article will help you understand the right timing, techniques, and care tips.

Why Hedge Trimming Matters

Trimming your hedges isn’t just about making them look good — it’s about keeping them healthy. Regular pruning:

  • Encourages new and strong growth

  • Keeps hedges in shape and balanced

  • Prevents overgrowth and pest issues

  • Improves sunlight and air circulation

Neglecting your hedge can lead to uneven growth, disease, or dead branches. With Sydney’s changing weather, following a seasonal pruning calendar helps your plants thrive all year long.

 Spring (September – November): The Season for Growth

Spring is one of the most important seasons for hedging and pruning Sydney gardens. This is when plants wake up from their winter rest and start growing quickly.

What to do:

  • Lightly trim new growth to maintain shape.

  • Remove any dead or frost-damaged branches.

  • Avoid heavy pruning early in the season — wait until the new growth is strong.

Pro tip: If you have flowering hedges like lavender or camellia, prune right after they finish blooming to avoid cutting off next season’s buds.

Summer (December – February): Control and Shape

In Sydney, summer brings strong sunlight and fast-growing plants. Regular hedge trimming during this time helps maintain the shape and prevents them from getting too thick.

What to do:

  • Trim every 4–6 weeks if your hedge grows fast.

  • Water deeply after trimming to reduce stress.

  • Avoid pruning during the hottest part of the day.

Extra care: For formal hedges like boxwood or lilly pilly, sharp tools and clean cuts keep edges neat. This is also the time to check for insects or scale buildup.

Autumn (March – May): Preparing for Cooler Months

Autumn is a great time to give your hedges a moderate trim. The growth rate slows down, and this is your chance to shape and tidy up your garden before winter.

What to do:

  • Trim back overgrown areas gently.

  • Remove dry or damaged branches.

  • Feed hedges with an organic fertilizer to help them stay strong through winter.

This seasonal trimming keeps your garden neat and prevents your hedge from becoming too dense or weak.

Winter (June – August): Rest and Light Pruning

Winter in Sydney is usually mild, which means some plants still grow slowly. This is a good time for light pruning and cleanup.

What to do:

  • Remove deadwood and diseased branches.

  • Avoid heavy trimming since growth is minimal.

  • Sharpen your tools and prepare for spring trimming.

If your hedge is evergreen, a light trim will keep it tidy. For deciduous types, wait until late winter before new buds appear.

How Often Should You Trim Hedges?

The frequency depends on your hedge type and growth rate:

Hedge Type

Suggested Trimming Frequency

Fast-growing (e.g., lilly pilly, privet)

Every 4–6 weeks during growing season

Medium growth (e.g., viburnum, murraya)

Every 2–3 months

Slow-growing (e.g., boxwood)

2–3 times a year

For most homeowners, regular hedging and pruning in Sydney means a quick trim every few months keeps things tidy and healthy.

Simple Tips for Healthy Hedges

  1. Always use sharp, clean shears or trimmers.

  2. Water your hedge deeply after trimming.

  3. Don’t trim too hard during hot weather.

  4. Feed your plants with compost or fertilizer twice a year.

  5. Keep the base wider than the top so sunlight reaches all leaves.

Following these small steps will make your hedge greener, fuller, and more attractive all year round.
