How to grow Nectarine in New Zealand
Nectarines are smooth-skinned peaches, grown the same way and ripe in midsummer, and home-grown fruit left to ripen fully on the tree tastes far better than anything in the shops. They are self fertile and grow in most of New Zealand, needing cold winters, warm summers, full sun and good drainage. The keys to success are protective sprays against leaf curl before the buds open, and pruning in late summer rather than winter.

Where to plant
Plant nectarines in an open, sunny, sheltered spot. Do not bother if the site gets less than half a day of sun; full sun gives the best fruit and colour. They tolerate a range of soils but not waterlogging, even for short periods, so raise the bed on heavy ground.
Nectarines need cold winters and hot summers. Spring frosts can damage the blossom in southern and inland districts, and humid northern summers bring brown rot and leaf curl, so choose a variety suited to your climate.
- Northland, Auckland, Waikato and Bay of Plenty: choose low-chill varieties such as Fantasia, as some cultivars crop poorly in the north, and plan a spray programme for leaf curl and brown rot.
- Central North Island, Wellington, Nelson and Marlborough, and Canterbury: well suited. Plant where cold air drains away so frost does not catch the blossom.
- Otago and Southland, and Central Otago: Central Otago's hot summers suit nectarines well; avoid frost pockets and choose later-flowering varieties where spring frosts are common.
Choosing a variety
| Variety | Notes |
|---|---|
| Early Red II | Early season, yellow flesh, freestone |
| Fantasia | Low chill, yellow flesh, freestone; suits warmer districts |
| Goldmine | Midseason, white flesh, freestone; a popular, reliable home cropper |
| Queen Giant | Midseason, white flesh, freestone |
| Snow Queen | White flesh, freestone, big fruit |
| Red Gold | Late season, yellow flesh, freestone |
| Dwarf types (for example Garden Delight, Nectar Babe) | Compact trees for pots and small gardens |
Buy grafted trees; seedlings are not true to type and take years to fruit. Nectarines are self fertile, though more than one tree can improve cropping. Freestone fruit comes away from the stone; clingstone does not.
How to plant
- Plant bare-root trees in winter or early spring while dormant.
- Dig compost into a sunny, free-draining spot, and dig a hole wide enough to spread the roots.
- Plant at the depth the tree grew in the nursery, with the graft union above the soil.
- Water in well and mulch, keeping mulch off the trunk.
- Cut the young tree back after planting to start an open vase shape of three or four main branches.
Watering and feeding
Water well while trees establish and during long, dry spells while fruit is developing; dry soil at that stage gives small fruit. Mulch over summer to hold moisture.
Feed in spring and summer with a balanced fruit tree fertiliser with plenty of potassium.
Pruning and care through the year
- Leaf curl control: spray copper at leaf fall in autumn and again at bud swell in late winter, before the buds open. Once curled leaves appear it is too late for that season.
- Prune in late summer after fruiting, or in early to mid autumn at the latest, sealing cuts if you prune in autumn. Do not prune in winter, which spreads silver leaf disease spores into fresh cuts.
- Prune to an open vase shape that lets in light and air. Nectarines fruit on the previous summer's growth, so keep renewing young wood.
- Thin young fruit to about 15 to 20 cm apart once it has set, for bigger fruit and less branch breakage.
- Net trees as the fruit ripens to keep birds off, and clear up fallen and mummified fruit to reduce brown rot.
Harvesting
Nectarines ripen between January and March, depending on variety and district. Watch for full colour, size and slight softening at the stem end, and pick carefully, using secateurs if needed, to avoid bruising the fruit and damaging the fruiting spurs.
Fruit left to ripen fully on the tree has the best flavour. Ripe nectarines keep a few days in the fridge; firm fruit softens on the bench.
Growing in pots
Dwarf nectarines such as Garden Delight and Nectar Babe grow well in large pots at least 50 cm wide in full sun. Use quality potting mix, water regularly in summer and feed in spring and summer. A pot can be moved under cover in late winter, which helps keep rain, and leaf curl, off the opening buds.
Companion planting
Low plants under nectarines can feed the soil and bring in beneficial insects, but keep the area under young trees clear of grass.
Good companions
- Nasturtium A low flowering groundcover that brings in bees at blossom time.
- Garlic A traditional companion planted under peaches and nectarines.
- Chives A low perennial for the edge of the root zone that flowers for bees.
- Comfrey Its leaves make a nutrient-rich mulch; keep it away from the trunk.
- Tansy (a strong-smelling herb said to deter some insects. It spreads and is toxic if eaten, so keep it in a contained spot away from children and animals)
Keep apart
Avoid planting these close to nectarine.
Pests and diseases
Leaf curl and brown rot are the main problems for nectarines in New Zealand, especially in wet springs and humid summers. Silver leaf and bacterial canker enter through wounds, so pruning time matters.
Pests to watch for
- Birds Ripening fruit pecked on the tree; net as fruit colours.
- Guava moth Caterpillars tunnelling in the fruit, mainly in the upper North Island.
- Scale Small crusty bumps on stems with sticky honeydew; a winter oil spray helps.
Diseases to watch for
- Peach leaf curl New leaves thick, puckered and red as they open in spring, then falling. Spray copper at leaf fall and bud swell.
- Brown rot Blossom and twig blight in wet springs, and soft brown rot with grey spore tufts on ripening fruit. Remove mummified fruit.
- Silver leaf Leaves with a dull, silvery sheen on whole branches, and dark staining in the wood. Prune only in late summer and autumn.
- Bacterial canker Dead buds, oozing gum and branches that wilt and die back in spring.
Common questions
When do I spray nectarines for leaf curl?
Spray copper at leaf fall in autumn and again at bud swell in late winter, before the buds open. Once curled leaves appear, it is too late to spray for that season.
When should I prune a nectarine tree?
In late summer after fruiting, or early to mid autumn at the latest. Avoid winter pruning, which spreads silver leaf disease into fresh cuts.
When are nectarines ripe?
Between January and March depending on the variety. Look for full colour and slight softening at the stem end, and taste one first.
Do I need two nectarine trees?
No. Nectarines are self fertile, though a second tree can improve cropping.
Which nectarine is best for Auckland?
A low-chill variety such as Fantasia, as some cultivars crop poorly in the north. Plan for copper sprays against leaf curl and brown rot in humid summers.
Should I thin nectarine fruit?
Yes. Thin young fruit to about 15 to 20 cm apart after it sets. The remaining fruit grows bigger and branches are less likely to break.
