How to grow Peach in Australia
Peaches are one of the most rewarding backyard fruit trees, with spring blossom and sweet summer fruit. The key is choosing a variety whose chill needs match your winter: low-chill peaches crop in south east Queensland, while high-chill types suit Melbourne, Canberra and Adelaide. Plan for leaf curl in winter and fruit fly in summer.

When to plant by region
| Region | When to plant | Regional note |
|---|---|---|
| South East Queensland | June to August | |
| Northern Rivers NSW | June to August | |
| Sydney & Coastal NSW | June to August | |
| Melbourne & Victoria | June to August | |
| Adelaide & SA | June to August | |

| Tasmania | June to August | Plant bare-root Jun to Aug. Choose late-flowering varieties to dodge spring frost. Spray for leaf curl in winter. |
| Canberra & ACT | June to August | |
| North Queensland | Not suited | Not viable. Even low chill peaches need 100 plus chill hours; the Townsville coast does not deliver them. |
| Darwin & Top End | Not suited | Not viable. Even low chill peach needs cool winter nights Darwin never gets. |
Not to be confused with: Nectarine, which is the same species with smooth skin instead of fuzz, grown in exactly the same way.
Where to plant
Plant in full sun in deep, fertile, well-drained soil. Peach trees do not tolerate poorly drained ground, where the roots rot, and struggle in light, shallow soil. They flower early, so avoid frost hollows where spring frost can kill the blossom.
Do not plant where potatoes, tomatoes or strawberries have grown for years, as those crops build up verticillium wilt in the soil, which also attacks stone fruit.
Every peach variety needs a certain amount of winter cold, measured as chill hours (hours below about 7°C), to flower and fruit well. Matching the variety to your winter is the most important choice you make.
- South East Queensland and the Northern Rivers: grow only low-chill varieties, needing about 150 to 300 hours. Fruit fly control is essential.
- Sydney and Perth: low to medium chill varieties suit the coast; inland and cooler suburbs can grow medium chill types.
- Melbourne, Adelaide and Canberra: most varieties grow well, including high-chill types needing 600 hours or more.
- Hobart: choose late-flowering varieties to dodge spring frost, and spray for leaf curl in winter.
- North Queensland and Darwin: not suited. Even low-chill peaches need more winter cold than the tropical coast provides.
Choosing a variety
| Climate | Examples and chill needs |
|---|---|
| Subtropical and warm coastal (SEQ, Northern Rivers, coastal NSW) | Low-chill varieties needing about 150 to 300 hours, such as Tropic Snow, Tropic Beauty, Flordaprince and Florda Gem |
| Mild temperate (around 400 hours) | Medium-chill varieties suited to cooler coastal and inland areas; ask a local nursery |
| Cold winters (Melbourne, Canberra, Adelaide, Hobart) | High-chill varieties needing 600 hours or more, such as Anzac |
All peaches are self-fertile, so one tree is enough. Flesh can be white or yellow, and freestone (flesh comes away from the stone) or clingstone. Dwarf varieties suit pots and small yards.
How to plant
- Plant bare-root trees in winter while dormant; potted trees can go in from late autumn to spring. Avoid hot, dry weather.
- Soak a bare-root tree in a bucket of water for half an hour before planting.
- On poor soil, mix a bucket of compost into the soil you backfill with. On heavy soil, plant on a raised mound for drainage.
- Plant at the same depth as before, with the graft union above the soil, and stake the young tree.
- Water in deeply and mulch, keeping the mulch clear of the trunk.
Watering and feeding
Water young trees regularly in dry spells for the first couple of years. Moisture matters most from spring into early summer while the fruit is swelling; dry trees give small fruit. Water deeply rather than often, and ease off a little as the fruit ripens. Trees in pots need steady watering all season.
Spread compost or well-rotted manure around the tree in late winter or spring, keeping it off the trunk, and feed with a balanced fruit tree fertiliser in early spring. Potted trees benefit from a liquid feed every couple of weeks in the growing season.
Pruning and care through the year
- Leaf curl: spray a registered fungicide, such as a copper or lime sulphur product, while the tree is dormant, timed when the buds are swelling but before they open. Spraying after the buds open is too late. Where leaf curl has been bad, spray at leaf fall, just before bud swell and about a week later.
- Thin the fruit when it is between hazelnut and walnut size, leaving one fruit about every 15 to 20 cm. The remaining fruit grows larger and the tree is less likely to snap branches.
- Peaches fruit almost entirely on shoots that grew the previous year, so prune every year to replace old fruited wood with new growth. Train young trees to an open goblet of about four main branches.
- Prune in dry weather after harvest in summer, with a lighter tidy in autumn if needed. Avoid pruning in cold, wet weather, which lets in bacterial canker.
- Remove and destroy mummified fruit and cankered twigs, which carry brown rot into the next season.
Harvesting
Peaches ripen from late spring through summer, depending on the variety and district. They are ready when the background colour has changed from green to cream, yellow or gold, the flesh near the stalk gives slightly, and the fruit smells sweet. Cup the fruit in your palm and lift or twist gently; ripe fruit comes away easily.
Check the tree every day or two, as fruit ripens over a few weeks. Fruit picked slightly early ripens on the bench, but tree-ripened fruit tastes best. Keep ripe fruit in the fridge for 3 to 5 days, or slice and freeze it.
Growing in pots
Dwarf peach varieties crop well in a pot at least 45 to 50 cm wide and deep, in a sunny, sheltered spot. Use quality potting mix, water regularly, and feed through the growing season. A potted tree can be moved under cover in wet weather at bud burst, which helps with leaf curl.
Using it
Eat peaches fresh, slice them into salads and desserts, grill or poach them, or bottle, freeze or make jam from a glut.
Companion planting
Keep the root zone of a young stone fruit tree clear of competing plants and away from soil that has grown tomato-family crops. Low herbs and flowers at the edge of the canopy are fine.
Good companions
- Nasturtium A low, flowering cover for the edge of the root zone that brings in helpful insects. Keep it trimmed back from the trunk.
- Garlic Takes little room and grows happily at the sunny edge of a fruit tree bed. Claims that it prevents leaf curl are not proven.
- Chives A small clumping herb for the bed edge whose flowers bring in bees.
- Tansy Grown under fruit trees in the hope of deterring insects, though evidence is limited.
Keep apart
Avoid planting these close to peach.
Pests and diseases
Leaf curl, brown rot and fruit fly cause most peach problems in home gardens. Most are prevented by timing: winter spraying, summer hygiene and protecting ripening fruit.
Pests to watch for
- Queensland fruit fly Small sting marks on ripening fruit, which then rots with maggots inside. Use exclusion netting or fruit bags, traps or baits, and destroy fallen fruit.
- Scale Small bumps on stems and twigs, with sticky honeydew and sooty mould.
- Borer Small holes in the bark with sawdust-like frass and oozing gum on the trunk or branches.
Diseases to watch for
- Peach leaf curl New leaves in spring are thickened, puckered and red or purple, then drop. Fruit may have raised, rough patches. Prevent it with a dormant spray at bud swell.
- Brown rot Blossoms turn brown and shrivel in wet weather, and ripening fruit develops a spreading firm brown rot with fawn spores, drying into mummies.
- Bacterial canker Sunken, gummy cankers on branches and dieback in spring, with small holes in the leaves. Prune only in dry weather.
Common questions
What is the best peach tree for Brisbane?
A low-chill variety needing only about 150 to 300 chill hours, such as Tropic Snow, Tropic Beauty or Flordaprince. High-chill varieties like Anzac will not fruit well in south east Queensland.
When should I spray my peach tree for leaf curl?
While the tree is dormant, timed for when the buds are swelling but before they open, in late winter. Once the leaves have emerged it is too late. Where it has been bad, spray at leaf fall, just before bud swell and about a week later.
Why are my peach leaves curled and red?
That is peach leaf curl, a fungus that infects new leaves in cool, wet spring weather. Affected leaves drop and the tree regrows, but repeated attacks weaken it over the years. Prevent it with a dormant spray at bud swell next winter.
When should I prune a peach tree?
After harvest in summer, in dry weather, with a lighter tidy in autumn if needed. Peaches fruit on the previous season's shoots, so prune every year to replace old fruited wood with new growth.
Should I thin peaches?
Yes. When the fruit is between hazelnut and walnut size, remove enough to leave one fruit about every 15 to 20 cm. The remaining peaches grow larger and branches are less likely to break.
How long does a peach tree take to fruit?
A grafted tree usually starts cropping 2 to 3 years after planting. Trees grown from a stone take longer and the fruit is often poorer than the parent.
Why is my peach tree not fruiting?
The variety may need more winter chill than your area provides, frost may have killed the blossom, or the tree may have been pruned too hard or at the wrong time. Check that the variety suits your climate.
