The best native hedge for most Sydney gardens is a lilly pilly, westringia or dwarf bottlebrush, planted in autumn or early spring and clipped lightly once or twice a year. Each one gives you an evergreen screen that supports birds and bees and needs less water than most exotic hedges once established.
This guide covers the best Australian native hedge plants, spacing, planting steps, trimming, costs and the mistakes we see most often. For the wider picture, start with our hedges guide.
Key points
- Lilly pilly, westringia, bottlebrush and tea-tree are the most common native hedge choices in Sydney, and each suits a different site and style.
- Plant in autumn or early spring, space plants according to the label (indicative — check the plant label or product instructions) and water through the first summer.
- A small hedge trim in Sydney typically costs about $69 to $205 per job, including GST (October 2026).
- Watch-out: clipping into bare wood or shearing too hard leaves brown patches that many native shrubs are slow to regrow.
Best native hedge plants for Sydney
These are the plants most often used as a native hedge in Sydney, with the traits that matter when you choose.
| Plant | Style | Size (indicative) | Best for | Watch-out |
|---|---|---|---|---|
| Lilly pilly (Syzygium and Acmena) | Formal or informal | Small to tall, by variety (indicative — check the plant label or product instructions) | Privacy screens, formal clipped hedges | Psyllid damage on susceptible varieties in humid summers |
| Westringia (coastal rosemary) | Informal to semi-formal | Low to medium (indicative — check the plant label or product instructions) | Coastal and sandy sites, low hedges | Dislikes wet, heavy soil |
| Dwarf bottlebrush (Callistemon) | Informal | Small to medium (indicative — check the plant label or product instructions) | Flowering hedge, wildlife | Prune after flowering |
| Tea-tree (Leptospermum) | Informal | Medium (indicative — check the plant label or product instructions) | Sunny screens, fine foliage | Can be short-lived in poorly drained soil |
| Correa | Informal | Low (indicative — check the plant label or product instructions) | Shaded garden borders | Needs good drainage and shelter |
| Honey myrtle (Melaleuca) | Informal to formal | Medium to large (indicative — check the plant label or product instructions) | Windbreaks and larger gardens | Check mature size before planting near fences |
Australian native hedging plants: formal vs informal hedges
Choose the style first, because it decides how often you need to trim and which plants suit.
| Style | Look | Trimming needed | Suitable native plants |
|---|---|---|---|
| Formal hedge | Tight, geometric, flat sides | Frequent light clipping through the growing season | Lilly pilly, some honey myrtles |
| Informal hedge | Soft, natural and flowing | One or two light trims a year | Westringia, bottlebrush, tea-tree, correa |
| Mixed hedge | Layered, varied heights and textures | Selective pruning of each species | Westringia with grevillea and bottlebrush |
| Low hedge | Knee to waist high edging | Light trims after flowering | Dwarf westringia, dwarf bottlebrush |
Where to plant a native hedge in Sydney
- Match the plant to the site: westringia suits sandy coastal gardens, while lilly pilly handles richer, moister soil.
- Give the hedge sun for most of the day, because shade makes native shrubs open and leggy.
- Leave enough width between the hedge and a fence or wall for the plants to reach their full spread (indicative — check the plant label or product instructions).
- Improve heavy western Sydney clay with compost and gypsum-free coarse material so water drains away from the roots.
- Keep native hedge roots clear of stormwater pipes, drains and paving, and check council rules for hedges beside footpaths.
- Plant lower informal species at the front and taller species behind if you are building a layered hedge.
How to plant a native hedge
- Mark a straight line with string and stakes, then dig a continuous trench or individual holes along it.
- Space each plant according to the label so the hedge joins up within a few years (indicative — check the plant label or product instructions).
- Water the plants in their pots before planting and loosen any circling roots.
- Set each plant so the top of the root ball sits level with the soil surface.
- Backfill, firm lightly and water deeply to settle the soil around the roots.
- Mulch along the line, keeping it clear of the stems.
- Use a slow-release native or general fertiliser exactly as the label directs, avoiding high-phosphorus products on sensitive natives.
- Water before 10 am or after 4 pm, use a trigger nozzle on hand-held hoses and never leave a hose running unattended.
Native hedge trimming and care
| Task | When | How |
|---|---|---|
| Tip pruning young plants | First two years, spring and summer | Pinch or snip growing tips to build dense side branching. |
| Formal clipping | Spring to early autumn | Trim lightly, keeping the base slightly wider than the top. |
| Informal pruning | After flowering | Cut back spent stems to keep shape without losing next year’s flowers. |
| Watering | Spring to autumn | Soak deeply until established. Drip irrigation may run between 10 am and 4 pm. |
| Feeding | Early spring | Use a low-phosphorus fertiliser suitable for natives, following the label. |
| Pest and disease watch | Spring and summer | Check for psyllids and scale. For insects, see a pest controller. |
- Trim powered hedge trimmers within NSW hours: 7 am to 8 pm Monday to Saturday, and 8 am to 8 pm on Sundays and public holidays.
- Wear eye and hearing protection, closed shoes and gloves, and keep children and pets away.
- Disconnect the battery or spark plug before you touch the blades.
- Book a licensed arborist for tall hedges, work near power lines or anything above head height.

Common mistakes to avoid
- Planting a large honey myrtle or tall lilly pilly close to a boundary, then fighting its width for years instead of picking a compact variety.
- Shearing flat into bare wood, which leaves brown patches because many natives do not reshoot well from old stems.
- Over-feeding with fertiliser high in phosphorus, which can harm sensitive natives such as some grevilleas and banksias.
- Ignoring drainage, so roots sit wet after rain and the plants decline within a season or two.
- Choosing lilly pilly varieties prone to psyllids in humid areas instead of a more resistant variety.
- Trimming before 7 am or after 8 pm and annoying neighbours, who can complain to council.
FAQ: Australian native hedge
What is the best native hedge in Australia?
For most Sydney gardens, lilly pilly makes the best formal native hedge and westringia the best informal one. Choose by site: westringia for sandy, coastal sun, lilly pilly for richer soil. Check the mature size on the label and ask your nursery which variety suits your suburb.
What are good native hedging plants for Australia?
Westringia, dwarf bottlebrush, tea-tree, correa and lilly pilly are the most common native hedging plants. They differ in height, flowering and water needs. Match each to your sun, soil and the look you want, and ask a native nursery for local advice.
What are the best informal hedge plants in Australia?
Westringia, bottlebrush, correa and tea-tree make soft, flowing informal hedges. They need only one or two light trims a year, usually after flowering. They suit relaxed gardens, coastal blocks and wildlife-friendly planting better than tightly clipped formal hedges.
How do you keep a native hedge dense?
Tip-prune young plants regularly so they branch from the base, then trim lightly rather than hard. Avoid cutting into bare wood, keep the base slightly wider than the top, and water and mulch through the first summer.
