Syzygium lilly pilly is an Australian native evergreen tree or shrub with glossy leaves, fluffy flowers and colourful edible berries, and it suits Sydney gardens that need a dense hedge or screen. Most gardeners choose a compact, psyllid-resistant variety, plant it in well-drained soil and trim it two or three times a year.
This guide covers what a lilly pilly is, the main varieties, where to plant them, how to look after them and what to do about bumps on the leaves.
Key points
- Syzygium lilly pilly plants range from small hedging shrubs to tall trees, so check the mature size on the nursery label before you buy (indicative — check the plant label or product instructions).
- They grow best in sun to part shade with well-drained soil, regular water while young and mulch around the base.
- Maintenance is moderate: expect to trim a hedge a few times a year, and a small hedge trim in Sydney typically costs about $115 per job (October 2026).
- Watch for bumpy, pimpled new growth, which usually signals psyllids; choose a resistant variety such as Resilience and book a licensed pest controller if the problem is severe.

Lilly pilly hedging and the Syzygium australe hedge
A hedge is the most common use for these plants, and dense foliage down to ground level makes them good privacy screens. Compare them with other hedges in our guide to hedge plants for Sydney gardens, or see the detailed lilly pilly hedge guide.
- Choose a Syzygium australe hedge when you want fast cover and a plant that responds well to regular shaping.
- Pick a small lilly pilly hedge variety for front borders where tall growth would block windows or paths.
- Check each plant tag for the mature size, because a hedge plant sold as compact can still outgrow a narrow bed.
- Compare with a murraya hedge if you want scented flowers, and note that murraya has different pruning needs.
- Consider Rhaphiolepis Snow Maiden or the Geisha Girl plant if you want a lower, more formal border.
- Expect to trim two or three times a year during active growth, and a small hedge trim in Sydney typically costs $69 to $205 per job.
Where to plant syzygium lilly pilly in Sydney
- Choose a sunny or part-shaded spot, because dense shade slows growth and encourages thin, leggy branches and more disease.
- Plant in well-drained soil. In western Sydney clay, mix in organic matter and mound the planting site slightly so water does not pond around the roots.
- Allow for spacing between plants that matches the mature width on the label (indicative — check the plant label or product instructions).
- Keep large varieties well back from pipes, paths and house footings, and check the label for the root spread of tall types.
- Use a compact variety in a large pot on balconies and courtyards, with premium potting mix and a saucer that never holds standing water.
- On exposed coastal blocks such as the Northern Beaches, give new plants a windbreak for their first season.
How to plant a lilly pilly
- Water the plant in its pot and leave it to drain before you start.
- Dig a hole about twice as wide as the root ball and no deeper than the pot (indicative — check the plant label or product instructions).
- Loosen circling roots gently with your fingers.
- Set the plant level with the surrounding soil and backfill without stamping hard.
- Water slowly until the soil is soaked, keeping to the Sydney Water Wise Guidelines: water before 10 am and after 4 pm, and use a trigger nozzle on a hand-held hose.
- Spread mulch around the plant and keep it clear of the trunk.
- Check moisture weekly for the first season, especially in hot, dry spells.
Caring for lilly pilly: soil, water and feeding
| Task | When | How |
|---|---|---|
| Watering | All year, more in summer | Water deeply and less often once established. Irrigation may run between 10 am and 4 pm if it is smart or drip, otherwise water early or late. |
| Lilly pilly soil requirements | At planting | Well-drained soil with plenty of organic matter. Improve heavy clay and avoid compacted, soggy ground. |
| Feeding | Spring and early autumn | Use a slow-release fertiliser registered for natives or hedges and follow the label exactly. Keep pets and children off treated areas until the label says it is safe. |
| Mulching | Autumn or spring | Spread coarse mulch around the base to hold moisture and suppress weeds. |
| Trimming | After flushes of new growth | Trim lightly and often rather than cutting hard into bare wood. |
| Pest and disease watch | Humid summers | Check new growth for bumps or curling. For serious infestations, book a licensed pest controller. |
Pruning syzygium lilly pilly as a hedge or screen
- Trim in spring after the first flush of growth and again in late summer, and avoid hard cuts in the heat of midsummer.
- Shape the hedge slightly wider at the base than the top, so light reaches the lower leaves and the hedge stays dense to the ground.
- Use sharp, clean hand shears or hedge trimmers, and wear eye protection, gloves and closed shoes.
- Disconnect the battery or power before you clear a jammed blade, and keep children and pets away from the work area.
- Run powered trimmers only during legal hours: not before 7 am or after 8 pm Monday to Saturday, and not before 8 am or after 8 pm on Sundays and public holidays.
- Book a qualified arborist if the plant is a full grown lilly pilly tree, close to power lines or above head height, and check your council’s tree rules before heavy cutting.
Lilly pilly fast growing: how big does a mature lilly pilly get?

| Is lilly pilly fast growing? | Many varieties grow quickly in warm, moist, sunny conditions, but growth depends on the variety and soil | Feed and water well in the first two seasons |
| How big is a full grown lilly pilly tree? | Tall varieties can become large trees if left unpruned (indicative — check the plant label or product instructions) | Choose a variety whose mature size fits the space |
| What does a mature lilly pilly look like? | A dense canopy with glossy leaves, creamy flowers and clusters of coloured berries | Prune to keep it clear of roofs and wires |
| Is a lilly pilly price high? | Prices change with pot size and variety (indicative — check the nursery or Bunnings for current pricing) | Compare pot sizes against the time you can wait for cover |
Common lilly pilly problems and bumps on leaves
| Symptom | Likely cause | Fix |
|---|---|---|
| Bumps or pimples on new leaves | Psyllid feeding, common in humid Sydney summers | Trim off affected tips and plant a resistant variety. For severe cases, book a licensed pest controller. |
| Yellow leaves | Waterlogging, poor drainage or nutrient shortage | Improve drainage, check moisture and feed with a product registered for the plant |
| Leaf drop in summer | Heat stress or dry roots | Mulch and water deeply early or late, within the Water Wise Guidelines |
| Thin, patchy hedge | Too much shade or trimming only the tips | Move to a sunnier spot or trim more evenly |
| Sooty black coating | Mould growing on insect honeydew | Treat the underlying cause and book a licensed pest controller |
| Brown leaf edges | Frost burn or wind scorch | Shelter young plants and wait for spring regrowth |
FAQ: lilly pilly questions
What is a lilly pilly?
A lilly pilly is a common name for a group of evergreen Australian native trees and shrubs, mostly in the genus Syzygium. They have glossy leaves, fluffy summer flowers and coloured berries. Gardeners use them for hedges, screens and feature trees, and many varieties suit Sydney conditions well.
What are lilly pillies?
Lilly pillies are the many species and cultivars sold under the lillipilly name, including Syzygium smithii, Syzygium australe and riberry. They vary in size, leaf colour and psyllid resistance. Always check the botanical name and mature size on the label before you plant one.
Why does my lilly pilly have bumps on the leaves?
Bumps or pimples on new growth usually come from psyllids feeding on the leaves. The damage is mostly cosmetic, but heavy attacks can weaken plants. Trim affected tips, consider a resistant variety, and book a licensed pest controller if the infestation keeps returning.
Are lilly pilly berries safe to eat?
Some lilly pilly berries are widely eaten, but varieties differ in taste and quality. Positively identify the plant before you eat any fruit, and do not eat berries from plants that may have been sprayed. If your pet eats berries and seems unwell, contact your vet.
