A lilly pilly hedge is one of the best fast, dense screens for Sydney gardens, as long as you choose a psyllid-tolerant variety and trim it little and often. Plant it in full sun to part shade, space it by the variety’s mature width and prune after each flush of growth.
This guide covers varieties, spacing, fertiliser, pruning timing, costs and the mistakes we see most. It is part of our wider series on hedges.
Key points
- Choose the variety by the height and width you want, because lilly pilly ranges from compact hedges to large trees.
- Prune lightly after each growth flush in spring and summer, and avoid hard cuts in heat or just before frost.
- Feed with a slow-release fertiliser suited to natives or evergreen shrubs, following the label for rate and timing.
- Professional trimming of a small hedge in Sydney typically costs about $115 per job (October 2026).
Lilly pilly varieties for a lilly pilly hedge
Lilly pilly, lillipillies, lilypilly and Australian lilly all describe the Syzygium group (the Acmena genus is now included in Syzygium). Syzygium varieties differ greatly in size, leaf colour and pest tolerance, so match the plant to the job.
| Type | Best for | Notes |
|---|---|---|
| Syzygium smithii (common lilly pilly) | Traditional informal screens | Grows large; tolerates regular shaping but may suffer psyllid damage on new growth |
| Syzygium australe (brush cherry) | Dense hedges and screens | Good for clipped hedges; named forms vary in height |
| Syzygium luehmannii (riberry) | Taller screens and feature hedges | Produces edible fruit; positively identify any fruit before eating |
| Syzygium paniculatum (magenta cherry) | Formal hedges in warm gardens | Often sold as a clipped hedge plant; check council weed advice for your area |
| Resilience lilly pilly | Hedges where psyllid is a problem | See our lilly pilly Resilience guide |
| Straight and Narrow lilly pilly | Tight side passages and narrow beds | Compare it in our Straight and Narrow guide |
Large lilly pilly and advanced lilly pilly hedge plants
Nurseries sell lilly pilly in tubes, pots and advanced bags, and the size you buy decides how quickly the hedge fills in. Check the tag for pot size and expected mature height (indicative — check the plant label).
- Choose advanced plants if you need privacy quickly, and expect to pay noticeably more per plant than for tubestock.
- Pick tubestock or small pots for long runs, because they establish well and cost less across a whole boundary.
- Match large lilly pilly to wide beds, since big varieties become trees if you stop pruning.
- Look for glossy, evenly coloured new growth, and avoid plants with pitted or distorted leaves.
- Buy all plants for one hedge from the same batch so the growth rate and leaf colour match.
- Check your council’s rules on hedge height near boundaries and overhead power lines before you plant.
Lilly pilly screening hedge: Syzygium lilly pilly hedge choices
A lilly pilly screening hedge works best when the plant’s natural habit matches the screen you need. Lilly pilly hedges hit by psyllid in humid Sydney summers show pitted, bumpy leaves, and choosing a tolerant form helps.
- Use upright varieties for narrow side boundaries, so you spend less time cutting back sideways growth.
- Use larger varieties on bigger properties where you can leave a wider planting bed.
- Consider other hedges as alternatives, such as the murraya hedge in sunny positions.
- Look at Rhaphiolepis Snow Maiden for a lower, tidy hedge in part shade.
- Check the Geisha Girl plant if you want a lower, compact edging.
- Read the hedge plants guide to compare other species before you commit.
How far apart to plant a lilly pilly hedge
Spacing depends on how fast you want the gaps to close and the variety’s mature width. Most compact hedge forms go in closer than large screening types.
- Read the tag for mature width, then plant at roughly half that width for a faster hedge, about 60 cm to 1 m apart for many compact forms (indicative — check the plant label).
- Mark a straight line with string and pegs so the hedge doesn’t wander.
- Dig each hole as deep as the root ball and about twice as wide, then loosen heavy clay on the sides.
- Plant at the same level as the pot soil, backfill, firm gently and water in slowly.
- Mulch the bed, keeping mulch off the stems, and water following the Sydney Water Wise Guidelines: before 10 am or after 4 pm, using a trigger nozzle.
- Tip-prune the first growth to encourage branching from the base, which is how you avoid bare lower stems.
What is the best fertiliser for lilly pilly
The best fertiliser for lilly pilly is a slow-release product made for natives or evergreen shrubs, applied in the growing season. Always follow the label for rates and protective equipment.
- Feed in spring when new growth starts, and again in early summer if the hedge looks pale.
- Choose a product labelled for native plants if your soil is low in phosphorus, as the label will say.
- Water before and after feeding, and keep fertiliser off the foliage and out of drains and waterways.
- Avoid heavy nitrogen feeding, because soft new growth attracts psyllid.
- Use Seasol or a similar seaweed tonic as the label directs to help roots settle after planting.
- Keep children and pets off treated beds until the label says it is safe.
When to prune lilly pilly in Australia
| Season | Pruning job | Notes |
|---|---|---|
| Spring (Sep–Nov) | Light trim after the first flush | Best time to shape a young hedge and remove stray shoots |
| Summer (Dec–Feb) | Tip trim only | Avoid hard cuts in heatwaves, which burn exposed foliage |
| Autumn (Mar–May) | Main shaping trim | Gives time to recover before cooler weather |
| Winter (Jun–Aug) | Rejuvenation on overgrown hedges, if needed | Avoid frost-prone times in western suburbs and the Blue Mountains |
How to prune lilly pilly
- Wear eye protection, gloves and closed shoes, and use a stable ladder only for low work; for height above reach, book a licensed hedge trimmer.
- Check the hedge for nesting birds before you start.
- Trim the sides first so the base stays slightly wider than the top, which lets light reach lower leaves.
- Cut just above a leaf node, and never cut into bare brown wood on a young hedge.
- Flatten the top last, using a string line for a straight finish.
- Rake up clippings and watch the NSW noise hours for powered trimmers: 7 am on weekdays and Saturdays, 8 am on Sundays and public holidays, finishing by 8 pm.

Common mistakes to avoid
- Planting too closely for a large variety, which crowds roots and leaves the base thin and bare.
- Pruning hard in a heatwave or just before frost, which scorches leaves and slows regrowth.
- Over-fertilising with nitrogen, which pushes soft growth that psyllid prefers.
- Watering at midday or leaving a hose running, both of which breach Water Wise rules.
- Treating insect infestations yourself without identifying them; for pests, book a licensed pest controller.
- Leaving a hedge untrimmed for years, then cutting back to bare wood that may not reshoot.
FAQ: lilly pilly hedge questions
What is the best fertiliser for lilly pilly?
Use a slow-release fertiliser made for natives or evergreen shrubs, and apply it in spring when growth starts. Follow the label for rate, protective equipment and watering in. Avoid high-nitrogen products, because they push soft growth that pests like.
How to prune lilly pilly?
Trim the sides first so the base stays wider than the top, then level the top using a string line. Cut just above a leaf node and avoid cutting into bare wood. Prune little and often rather than rarely and hard.
When to prune lilly pilly in Australia?
Prune lightly after each growth flush in spring and again in autumn for the main shape. Avoid hard cuts in summer heat and before frost. In cooler areas such as the Blue Mountains, wait until frost risk passes in spring.
How far apart to plant a lilly pilly hedge?
Plant about half the variety’s mature width apart for a fast hedge, often around 60 cm to 1 m for compact forms (indicative — check the plant label). Larger varieties need more room, so read the tag before you dig.
