How to prune: use clean, sharp tools, remove dead, damaged and crossing branches first, then shape the plant with cuts just outside the branch collar, at the right time of year for the species. The biggest mistake is cutting too much at once or at the wrong time, which weakens the plant and can remove next season’s flowers.
This guide explains what pruning is, when to prune, how to prune trees and shrubs, rules around council approval, and what a Sydney pro charges.
Key points
- The best time to prune most Sydney plants is straight after flowering or in the dormant season, and each species differs, so check the timing first.
- You need sharp secateurs, loppers and a pruning saw for small branches, plus eye protection and gloves.
- Check your council’s tree rules before cutting, and leave large trees, work above head height and anything near power lines to a qualified arborist.
- A Sydney arborist typically charges about $230 to $1,375 per tree for pruning, with a typical price of $520 (October 2026).
What is pruning?
Pruning is the selective removal of branches, stems or roots to improve a plant’s health, shape and safety. The table below defines the main terms.
| Term | Meaning | Why it matters |
|---|---|---|
| Pruning | Cutting living or dead parts to guide growth | Improves structure, flowering and plant health. |
| Trimming | Light cutting of tips and edges, often on hedges | Keeps hedges and shrubs tidy and dense. |
| Thinning | Removing whole branches back to a main stem | Lets light and air through the canopy. |
| Branch collar | The swollen ring where a branch meets the trunk | Cutting just outside it helps the wound heal. |
| Dormant season | The cooler months when deciduous trees rest | A common time to prune many deciduous trees. |
When to prune in Sydney
Timing depends on whether the plant flowers on old or new wood. Cold, wet weather in a western Sydney winter can also invite disease into fresh cuts.
| Season | What to prune | Why |
|---|---|---|
| Spring (Sep–Nov) | Spring-flowering shrubs and natives after their flowers fade | You keep next year’s buds and encourage fresh growth. |
| Summer (Dec–Feb) | Light trims on hedges and stray growth | Hot weather speeds regrowth, but avoid heavy cuts in a heatwave. |
| Autumn (Mar–May) | Summer-flowering shrubs and tidy-ups before winter | Plants recover while the soil is still warm. |
| Winter (Jun–Aug) | Deciduous trees and dormant roses | You can see the branch structure clearly without leaves. |
What you need to prune trees and shrubs
| Tool | What it’s for | Tip |
|---|---|---|
| Bypass secateurs | Cutting small stems cleanly | Keep the blades sharp and clean to avoid spreading disease. |
| Loppers | Cutting thicker branches | Long handles give leverage without straining your wrists. |
| Pruning saw | Larger branches you can reach from the ground | Never use it above head height or from an unstable ladder. |
| Hedge shears or trimmer | Formal hedges | Powered trimmers must follow NSW noise hours. |
| Gloves and eye protection | Protection from thorns, sap and flying debris | Wear closed shoes as well. |
| Pole pruner (hand) | Branches slightly out of reach | Keep clear of power lines at all times. |
How to prune: step by step
- Identify the plant and find out when it flowers, because that decides whether you prune now or wait.
- Clean your blades with a household disinfectant, then check that they are sharp enough to cut cleanly.
- Stand back and look at the whole plant, deciding which branches are dead, diseased, rubbing or crossing.
- Remove dead and damaged wood first, cutting back to healthy tissue just outside the branch collar.
- Take out crossing and inward-growing branches, so air and light can reach the centre.
- For a branch too heavy to hold, make an undercut first, then a top cut further out, then the final cut at the collar.
- Shape the plant lightly, removing no more than about a quarter of the canopy in one season (indicative — check the plant label).
- Step back and check the balance, then stop if the shape already looks good.
- Collect the cuttings and dispose of diseased material carefully, rather than composting it.
How to prune trees: tree pruning tips
Pruning trees is more serious than trimming a shrub. These tree pruning tips apply to small trees you can reach from the ground.
- Cut one branch at a time and step back, since you can always remove more but can’t put a branch back.
- Leave the branch collar and the branch bark ridge intact, and never cut flush to the trunk.
- Avoid topping, which means cutting large branches back to stubs and leaves weak regrowth.
- Prune during the right season for the species to protect flowers, fruit and plant health.
- Keep the tree’s natural shape, because heavy shaping often makes it unstable and unattractive.
- Book an arborist for any tree you can’t prune safely from the ground, and never cut near power lines.
When to prune popular trees in Sydney
Use this table as a general guide, and always check the label or ask a nursery about your exact variety.
| Tree | Best time to prune | Notes |
|---|---|---|
| Cherry blossom tree | Lightly, after flowering | Avoid cutting in cold, wet weather. |
| Maple tree | Late autumn to winter, when dormant | Avoid pruning when sap is rising in early spring. |
| Dwarf Japanese maple | Winter dormancy | Remove dead and crossing wood only, with minimal shaping. |
| Dwarf crepe myrtle | Late winter, before new growth | Avoid hard topping, which weakens the tree. |
| Magnolia Little Gem and Teddy Bear | Lightly, after flowering | Little pruning is needed beyond removing dead wood. |
| Port wine magnolia | After flowering in late spring | Trim lightly to keep a compact shape. |
| Flowering gum | Lightly, after flowering | Avoid cutting deep into old wood. |
| Frangipani | Late winter, before growth restarts | The sap can irritate skin, so wear gloves. |
| Illawarra flame tree | Lightly, after flowering | Large trees need an arborist. |
| Palms such as lady palm | Any time | Remove only dead fronds, never green ones. |
When to prune bottlebrush
Bottlebrush (Callistemon) is a tough native that flowers on the ends of its branches. Prune it straight after its flowers fade.
- Cut off spent flower spikes and a little of the new growth below them to encourage bushy growth.
- Prune in late spring to early summer for most varieties, once the main flowering is over.
- Avoid cutting deep into old bare wood, because bottlebrush can be slow to shoot from it.
- Shape lightly each year rather than cutting hard every few years.
- Check the label for your variety, because flowering times differ.
How to trim bushes and shrubs
For garden shrubs and hedges, regular light trimming beats occasional hard cuts. Roses have their own rules, so see our guide on how to prune roses.
- Trim lightly several times a year, rather than cutting back hard in one go.
- Cut the sides of a hedge slightly narrower at the top, so light reaches the lower leaves.
- Prune just above an outward-facing bud or leaf to direct new growth away from the centre.
- Avoid cutting into bare wood on conifers and many natives, because they may not regrow.
- Clean up clippings promptly, and respect NSW noise hours when using powered trimmers.
Council rules before you prune a tree
Most Sydney councils protect trees above a certain size or of listed species, and fines can apply for unapproved work.
- Check your council’s tree preservation rules before cutting any large branch or removing a tree.
- Read our guide to council tree removal permits to see how approvals work.
- Take photos of the tree and write down the species and the work you propose before you apply.
- Ask neighbours before pruning overhanging branches, and check strata by-laws if you live in a complex.
- Use a qualified arborist if the council requires a report for the work.
What to do about a stump after you prune or remove a tree
If a tree comes out, the stump is left behind. You can kill it, dig it out or have it ground.
- Read our guide on how to remove a tree stump to compare the methods.
- See stump removal cost for current Sydney pricing and what is included.
- Use chemicals only as the product label directs, and keep children and pets away.
- Book a stump grinder for large stumps, which are heavy and dangerous for homeowners.
- Check for underground pipes and cables before any digging or grinding.
Common mistakes with how to prune
- Pruning at the wrong time, which removes buds and reduces flowering next season.
- Removing too much canopy in one go, which stresses the tree and invites weak regrowth.
- Using blunt or dirty tools, which tear the bark and spread disease.
- Cutting flush to the trunk or leaving long stubs, both of which slow wound healing.
- Working near power lines, which is dangerous and a job for a qualified arborist.
- Pruning a protected tree without checking council rules first.
When to call an arborist (or a licensed specialist)
- The tree is large, or you can’t reach every cut safely from the ground.
- Branches are near power lines, which only qualified arborists should handle.
- You need a chainsaw above head height, which is unsafe for most homeowners.
- The tree is diseased, leaning or cracked, or has dead limbs hanging over a house.
- Council approval is required and a report or application is needed.
- Insects or pests are damaging the tree, so book a licensed pest controller, and book a licensed applicator for any paid weed spraying.

FAQ: how to prune
How to trim bushes?
Trim bushes lightly and often, cutting just above an outward-facing bud and keeping the top slightly narrower than the base. Avoid cutting into bare wood on conifers and many natives. Clean your blades first, and wear eye protection and gloves.
What is pruning?
Pruning is the selective removal of branches, stems or roots to improve a plant’s health, shape and safety. It includes removing dead or diseased wood, thinning crowded growth and shaping. Done well, it encourages strong structure and better flowering.
How to prune a tree safely?
Cut small branches from the ground using sharp tools, working just outside the branch collar. Remove dead and crossing wood first, and never take too much canopy. Leave large trees, work above head height and anything near power lines to a qualified arborist.
When to prune most trees in Sydney?
It depends on the species. Flowering trees are usually pruned lightly after their flowers fade, while many deciduous trees are pruned in winter dormancy. Check your tree’s timing, and avoid heavy cuts during heatwaves or cold, wet spells.
When to prune bottlebrush?
Prune bottlebrush straight after flowering, usually in late spring to early summer. Cut off spent flower spikes and lightly tip-prune for bushy growth. Avoid cutting deep into old bare wood, which may not reshoot.
Do you need council approval to prune a tree?
Often, yes. Most Sydney councils require approval to remove or significantly prune trees above set sizes or of listed species. Check your council’s tree rules before cutting, and ask an arborist if you’re unsure.
