The best hedge plants for most Sydney gardens are lilly pilly for tall privacy, murraya or westringia for medium screens, and small-leaf shrubs such as Japanese box for clipped formal edges. The biggest mistake is choosing a plant for its look without checking its mature size, which leads to constant trimming within a few years.
This guide compares popular hedge plants in Australia, explains when and how to plant them, and shows what hedge trimming costs in Sydney.
Key points
- Plant hedges in autumn or spring, when Sydney soil is warm enough for roots but the weather is not extreme.
- Pick a hedge plant by mature size, sun, soil and how tightly you want to clip it, and check the label for exact sizes.
- Powered hedge trimmers must follow NSW noise hours: 7 am to 8 pm Monday to Saturday, and 8 am to 8 pm on Sundays and public holidays.
- Small hedge trimming in Sydney costs about $69 to $205 per job, with $115 typical, including GST (October 2026).
When to plant hedge plants in Sydney
| Season | What to do | Why |
|---|---|---|
| Autumn (Mar to May) | Plant most evergreen hedging plants and water in well | Warm soil and cooler air let roots settle before summer |
| Winter (Jun to Aug) | Plan the line, prepare soil and order plants | Frost in the west can damage new growth on tender plants |
| Spring (Sep to Nov) | Plant, mulch and give the first light trim | Growth is strong, so new plants establish fast |
| Summer (Dec to Feb) | Water deeply and trim lightly | Humid summers invite disease and pests, such as psyllid on lilly pilly new growth |
What you need to plant hedge plants
| Item | What it is for | Tip |
|---|---|---|
| String line and pegs | Marking a straight planting line | Stretch the line before digging so the row stays true. |
| Spade and mattock | Digging holes in clay or compacted soil | Rough up the sides of each hole so roots can spread. |
| Quality garden mix and mulch | Improving soil and holding moisture | Keep mulch off the trunks to avoid rot. |
| Slow-release fertiliser | Feeding young plants | Use a product made for the plant type and follow the label. |
| Hedge shears or trimmer | Shaping the hedge as it grows | Sharp blades make cleaner cuts that heal faster. |
Best hedge plants for Sydney gardens
All sizes depend on the variety, so check the plant label (indicative — check the label for mature height and width).
| Plant | Best for | Notes |
|---|---|---|
| Lilly pilly | Tall privacy screens and tight clipped hedges | Choose psyllid-resistant varieties, and see lilly pilly resilience for tougher types. |
| Lilly pilly Straight and Narrow | Narrow side passages and tight boundaries | Compact habit, but still needs regular tip pruning. |
| Murraya | Medium to tall fragrant hedges | Fast and dense, though it needs regular trimming. |
| Rhaphiolepis Snow Maiden | Low to medium flowering hedges | Tough in sun and coastal conditions with spring blossom. |
| Geisha girl | Compact formal hedges | Check the label for the exact species and mature size. |
| Westringia | Native coastal and low-water hedges | Small grey-green leaves, though it can go woody if cut hard. |
| Japanese box | Formal clipped borders and small leaf hedges | Slow growing and neat, but needs good drainage. |
Hedge plants: step by step planting
- Mark the line with string, and check that it sits well clear of fences, pipes and paths (indicative — check the label for mature spread).
- Soak each pot in water until the bubbles stop, so the root ball is moist before planting.
- Dig each hole as deep as the root ball and wider than it, loosening clay on the sides.
- Space plants evenly along the line as the label advises, closer for tight screens and wider for relaxed hedges.
- Tease out circling roots, then set each plant so the top of the root ball is level with the soil.
- Backfill with existing soil, firm gently and water slowly to settle the roots.
- Spread mulch around the base, keeping it clear of the stems.
- Water within Sydney Water rules: before 10 am or after 4 pm, using a trigger nozzle, or drip irrigation any time.
Hedge plants for privacy screens
Privacy hedges need height and density, and they take a few seasons to fill in.
- Choose lilly pilly or murraya for the tallest screens, and check mature height against your boundary.
- Plant close enough to merge, but not so close that the plants compete hard for water and light.
- Keep the base wider than the top so lower leaves still get light and do not thin out.
- Avoid planting under power lines, where trimming becomes a job for a qualified arborist or the network operator.
- Talk to your neighbour before planting along a shared fence, as NSW has rules about high hedges and disputes.
- Allow space for ladder access so you can trim safely from the ground where possible.
Small leaf hedge plants for formal clipping
Small leaves suit tight, geometric shapes and neat edges.
- Japanese box and compact lilly pilly cultivars take clipping well and look sharp in front gardens.
- Westringia has fine foliage and works for informal rounded hedges in coastal sun.
- Clip lightly and often, because heavy cuts into bare wood may not reshoot on some plants.
- Use sharp shears for small-leaf plants so you do not tear leaves, which leaves brown edges.
- Mulch and feed regularly, as tightly clipped hedges lose a lot of leaf growth.
- Watch for fungal leaf spot in humid summers, and improve airflow rather than overwatering.
Hedge bushes for shade, coast and clay
Your site decides which hedge bushes will survive, so match plant to conditions.
- Shade: choose plants labelled for part shade, and expect slower, looser growth.
- Coastal wind: westringia and tough native shrubs handle salt-laden air better than fussy exotics.
- Heavy clay in western Sydney: improve drainage with gypsum or organic matter as the product label directs.
- Sandy soil: add compost and mulch, and water deeply until roots are established.
- Frost pockets: pick hardy varieties and protect young plants in their first winter.
- Pots and planters: use a good potting mix and expect to water far more often.
Common hedge plants mistakes
- Planting too close to a fence or wall, which leaves no room for trimming access.
- Ignoring mature size, so a hedge grows far taller than the space allows.
- Cutting a hedge flat on top and wider at the top, which shades and thins the base.
- Trimming heavily in the hottest weeks, which can scorch fresh growth.
- Skipping mulch and deep watering in the first summers, when most failures happen.
- Using powered trimmers outside the NSW noise hours.
When to call a gardener or a licensed specialist
- Tall hedges that need a ladder or work above head height are safer in a professional’s hands.
- Large trees or hedges that have become trees need an arborist and often council approval.
- Paid weed spraying under a hedge needs a licensed ground applicator, though routine garden maintenance has an exemption.
- Persistent pests such as psyllids or scale are a job for a licensed pest controller.
- Fence or retaining wall repairs along the hedge line need a licensed handyman or builder.
- If your hedge needs a regular trim, a gardener can do it on a schedule.

Hedge plants FAQ
What are the best hedge plants for Australia?
Lilly pilly, murraya, westringia and Japanese box are popular because they take clipping well and suit different spaces. Pick by mature size, sun and soil, and check the nursery label for exact dimensions. Our hedges guide explains more about each option.
What is a good hedging plant for a small garden?
A compact, small-leaf plant such as Japanese box, a narrow lilly pilly or Rhaphiolepis suits tight spaces. Check the mature width on the label, plant at the spacing advised and plan to trim lightly and often to keep the shape.
What are the best small leaf hedge plants?
Japanese box, westringia and compact lilly pilly cultivars all have small leaves that suit clipping. They need sharp shears, regular light trimming and good drainage. Avoid cutting into bare wood, because some plants will not shoot again.
When should I trim hedge plants in Sydney?
Give most hedges a light trim in spring and another in late summer or early autumn, avoiding the hottest and driest weeks. Check the plant’s growth habit and use powered trimmers only within NSW hours: 7 am to 8 pm Monday to Saturday, and from 8 am on Sundays and public holidays.
