How to Grow Oranges in New Zealand
Updated September 2026
Feeding schedule, citrus pests, and variety picks for every region
Orange trees are a long-term garden investment that pay off for decades. A mature tree produces hundreds of fruit per year with surprisingly little effort. Like all citrus, oranges need regular feeding and a sunny spot with good drainage. Get those two things right and the tree does most of the work.
This guide covers the best orange varieties for New Zealand home gardens, feeding and pest management, and regional planting times. For more on citrus pests, also see our pest management guide, and if your garden is too frosty for oranges in the ground, our guide to growing citrus in pots.
When to Plant in Your Region
Oranges do best in the warm north, in Northland, Auckland and the Bay of Plenty, and in sheltered coastal spots. Plant once the frosts are over. Within Waikato and the Bay of Plenty the coast suits oranges best, and inland Waikato needs a warm, sheltered spot. In Wellington and the lower North Island wind is a bigger problem than cold, so choose the warmest, most sheltered spot you have. Sunny coastal Nelson crops oranges well, but inland frost pockets need shelter. Canterbury is marginal: plant in November against a warm north facing wall and cover young trees on frosty nights. Winter frosts in the Central North Island are too hard for oranges, and a Meyer lemon or cumquat is the better citrus there. Otago, Southland and Central Otago are too cold for oranges outdoors. Choose your region below for local planting months.
Washington Navel
The classic eating orange. Seedless, easy to peel, sweet, and juicy. Fruit ripen in winter and spring. Crops well where frosts are light.
Valencia
The juicing orange. Produces fruit in summer when navels are out of season. Thinner skin, more seeds, and incredibly juicy. Excellent for households that juice regularly. Reliable and productive.
Blood Orange
Crimson-fleshed orange with a distinctive berry-like flavour. Needs cool winter nights to develop its red colour. Cooler inland nights in the Waikato help colour the flesh, and the cool nights and high sunshine of Nelson and Marlborough give well coloured fruit.
Cara Cara
Navel-type orange with pink-red flesh and a sweet, low-acid flavour. Beautiful colour, seedless, and excellent flavour. Ripens in winter.
Dwarf Orange
Grafted onto dwarfing rootstock to stay under 2 metres. Full-sized fruit on a compact tree. Perfect for pots, small gardens, and courtyards. Available in Navel, Valencia, and Blood Orange varieties.
Feeding and Care
Oranges have the same feeding needs as lemons: four feeds per year with a complete citrus fertiliser (August, November, January, April). See our organic feeding guide for more on choosing and using fertiliser.
Additional care tips specific to oranges:
- Oranges are slightly more cold-hardy than lemons. Washington Navel tolerates light frosts once established.
- Fruit can stay on the tree for weeks after ripening without losing quality. This makes oranges a "pick as you need" crop.
- Thin heavy crops by removing some fruit in spring. This prevents branch breakage and improves fruit size.
- Water deeply and infrequently. Oranges have deep root systems and prefer a good soak twice a week over daily light watering.
Citrus Pests
Oranges suffer from the same pests as other citrus trees. The main ones are:
- Citrus leaf miner: Silvery trails in new leaves. Spray new growth with horticultural oil.
- Scale: Brown or white bumps on stems and leaves. Spray with horticultural oil.
- Guava moth: The fruit pest that matters most in the warmer parts of the country. The caterpillar tunnels into developing fruit, citrus included. Net the tree once flowering has finished, use pheromone traps to tell when the moth is active, and bin fallen fruit sealed rather than composting it.

Common Problems
Dry or pithy fruit
Oranges left on the tree too long past ripeness become dry inside. Valencia oranges in particular need to be picked on time. Taste-test fruit regularly and harvest the whole crop once flavour peaks.
Alternating crops
Some orange trees produce a heavy crop one year and almost nothing the next. Thinning heavy crops in spring and consistent feeding help even out production over the years.
Splitting fruit
Fruit cracks open after rain following a dry period. Consistent watering prevents this. Mulch well and water deeply during dry spells, especially as fruit approaches ripeness.

When should I plant an orange tree in New Zealand?
Plant container-grown orange trees in spring, once the frosts are over. That means September to November in Northland and Auckland, October to November in Waikato and the Bay of Plenty, Wellington and Nelson and Marlborough, and November in Canterbury. Spring planting gives the tree the best chance to establish before winter. Avoid planting in summer heat or winter cold.
How long do orange trees take to produce fruit?
Grafted orange trees typically produce their first fruit in 2 to 3 years after planting. Full production takes 4 to 6 years. Dwarf varieties on dwarfing rootstock often fruit sooner.
What is the difference between Navel and Valencia oranges?
Navel oranges ripen in winter and spring, are seedless, and are best for eating fresh. Valencia oranges ripen in summer, have some seeds, and are ideal for juicing. Growing both gives you oranges for most of the year.
Can I grow oranges in pots?
Oranges grow well in large pots (at least 50 cm wide) when grafted on dwarfing rootstock. Use premium potting mix, feed four times per year, and water when the top few centimetres of mix dry out.
