Orange

Needs the warmest, most reliably sheltered position of the common home-garden citrus and is the least forgiving of marginal, cooler sites. Takes the longest of the three to reach a useable crop, typically 3-4 years after planting. Full sun and shelter from frost and wind are essential. No reliable outdoor Canterbury/Otago planting window is given here; further south, grow it in a large pot that can be moved under cover over winter.

When to plant by region

In Whangārei / Northland, Auckland, Tauranga / Bay of Plenty, Gisborne and Napier / Hawke's Bay: March-May and September-November. In Hamilton / Waikato, New Plymouth / Taranaki, Palmerston North / Manawatū-Whanganui, Wellington, Nelson and Tasman: September-November.

Growing stages

  1. Planting & establishmentFirst few months

    • Full sun and a genuinely warm, sheltered position matter more for orange than for any other common citrus type
    • Water regularly while roots establish; this is a moderate-water tree
    • In Canterbury/Otago there's no reliable outdoor planting window; grow in a large pot that can move under cover over winter

  2. Early growthFirst 1-2 years

    • Watch new growth for citrus leafminer tunnelling through leaves
    • Aphids and scale insects can cluster on soft new shoots, leading to sooty mould from their honeydew
    • First useable crop is typically 3-4 years away, the longest wait of the common citrus types

  3. Flowering & fruiting

    • Like other citrus, a single self-fertile tree crops well alone, though bees visiting the flowers still help fruit set
    • Continue checking for scale insects and citrus rust mite on developing fruit
    • Orange needs the most reliable warmth of the common citrus types; a cold snap during flowering can hit fruit set harder than it would lemon or mandarin

  4. MaturityOngoing annual harvest

    • Sooty mould signals an aphid or scale problem to deal with; wash off affected leaves once pests are controlled
    • Established trees yield around 25-40kg of fruit per season
    • Pick as fruit ripens; timing varies by cultivar and region rather than a single harvest window
