A plane tree is a large, fast-growing deciduous tree with mottled bark and broad, maple-like leaves, and the London plane is the one you see lining Sydney streets. It suits big blocks, parks and wide verges, but it is too large for most small suburban yards.
This guide covers size, planting, care, pruning, problems and costs. Use it alongside our main guide on how to prune before you pick up a saw.
Key points
- A mature tree grows very large (indicative — check the nursery label), so it needs wide space away from pipes, paths and buildings.
- It likes full sun and tolerates most Sydney soils, and it copes with city conditions better than many shade trees.
- Maintenance is moderate to high: expect autumn leaf drop, seed balls and regular pruning by a qualified arborist.
- Check your council’s tree rules before you prune or remove one, because many Sydney councils require approval.

Types of plane tree
Nurseries sell a few related species, and street plantings across the Inner West are often cultivated forms.
| Type | Size | Best use | Notes |
|---|---|---|---|
| London plane | Very large (indicative — check the label) | Street tree, park, large garden | Mottled bark and broad leaves, tolerates pollution and pruning |
| Named cultivars | Large (indicative — check the label) | Avenues and parks | Some are sold as more compact or with fewer seed balls |
| American sycamore | Very large (indicative — check the label) | Parkland | Related species, so check the tag to confirm which one you are buying |
| Oriental plane | Large (indicative — check the label) | Parkland, big gardens | Deeper-cut leaves than London plane |
| Smaller alternatives | Medium (indicative — check the label) | Suburban yards | See our guides to maple tree and dwarf crepe myrtle |
Where to plant a plane tree in Sydney
Location is the whole decision, because it outgrows a small yard within a few years.
- Plant only on a large block with plenty of open space, well away from boundaries, fences and neighbours’ windows.
- Keep it far from drains, pipes, paths and house footings, since large roots can lift paving and enter damaged pipes.
- Choose full sun, because shade makes the canopy thin and lopsided and slows growth.
- In heavy clay in western Sydney, loosen the planting area wide and not just deep, so roots can spread outwards.
- In sandy coastal soil, add organic matter and mulch to hold moisture, as covered in our guide to cherry blossom tree care.
- Do not plant under or near power lines, because pruning near lines is work for qualified arborists.
How to plant a plane tree
Plant small stock and let the tree grow into the space.
- Check the council rules and underground services before you dig, and confirm there are no overhead lines.
- Soak the pot well, then dig a hole much wider than the root ball and no deeper than it.
- Loosen any circling roots and set the tree so the top of the root ball sits level with the soil.
- Backfill with the original soil, firm it lightly and form a shallow watering basin around the stem.
- Mulch in a wide ring and keep the mulch clear of the trunk to avoid rot.
- Water slowly with a hand-held hose with a trigger nozzle before 10 am or after 4 pm, and never leave the hose running unattended.
Caring for a plane tree
| Task | When | How |
|---|---|---|
| Watering | Spring to autumn, more often in the first years | Water deeply before 10 am or after 4 pm, within the Water Wise Guidelines |
| Feeding | Spring | Use a registered fertiliser and follow the label for rate and protective gear |
| Mulching | Spring and autumn | Spread a wide, even ring and keep it off the trunk |
| Leaf clean-up | Autumn | Rake leaves from lawns and gutters, and compost or bag the green waste |
| Pruning | Winter, while the tree is dormant | Remove dead or crossing branches and hire an arborist for large limbs |
| Health check | Summer | Look for dieback, fungal spots and cracked limbs, then call an arborist |
Pruning a plane tree
Plane trees tolerate pruning, but the size of the tree decides who should do it.
- Prune in winter when leaves are down, because you can see the branch structure and the tree loses less sap.
- Cut only what you can reach safely from the ground, and leave anything above head height to a qualified arborist.
- Never prune near power lines, and book a licensed arborist for large limbs, climbing or chainsaw work.
- Check your council’s tree rules first, since pruning a large tree often needs approval.
- Keep powered tools inside the legal hours, which are 7 am to 8 pm on most days and 8 am to 8 pm on Sundays and public holidays.
- Expect pruning to cost about $230 to $1375 per tree, with a typical price near $520 (October 2026).
Common plane tree problems
| Symptom | Likely cause | Fix |
|---|---|---|
| Dark spots and early leaf drop | Fungal leaf disease in humid weather | Rake and bin fallen leaves and ask an arborist to inspect the tree |
| Itchy eyes or throat in spring | Fine hairs from leaves and seed balls | Wear eye protection and a mask when raking, and see a doctor if symptoms persist |
| Lifted paving or cracked pipes | Roots too close to hard surfaces | Book a licensed plumber or arborist to assess before cutting roots |
| Dead branches in the canopy | Drought, root damage or disease | Engage a qualified arborist to prune and assess safety |
| Bark peeling in patches | Normal for this species | No action needed unless the wood beneath looks diseased |
| Sticky leaves and black coating | Sap-sucking insects | Book a licensed pest controller to identify the insect |
Plane tree removal cost in Sydney

FAQ: plane tree questions
How big does a plane tree get?
It grows very large and spreads wide, so it suits parks and big blocks rather than small yards. Exact height and width depend on the cultivar and conditions, so check the nursery label. Plant it well away from buildings, pipes and boundaries.
Are plane trees messy?
Yes. They drop leaves in autumn, bark flakes through the year and seed balls that break into fine hairs. Raking is a regular job in streets lined with them. Wear eye protection and a mask when you clean up, and bag the green waste.
Do you need approval to prune or remove a plane tree?
Often yes. Most Sydney councils require approval to remove or heavily prune trees above set sizes or of listed species. Check your council’s tree rules before you cut, and book a qualified arborist for large trees or work near power lines.
Can you grow a plane tree in a small garden?
Not really. It outgrows small gardens and can damage pipes and paving. Choose a smaller tree instead, such as a dwarf crepe myrtle, or ask your nursery for compact options suited to your block size.
