Orange Growing Guide

Citrus sinensis


Crop Rotation Group



Warm, moist soil, well-enriched with organic matter. Oranges grafted onto a dwarfing rootstock may be grown in containers.


A sheltered spot in full sun. In gardens where the temperatures drop below 0 °C grow them in containers that can be moved into a warm, sheltered area during winter.

Frost tolerant

No. Certain Valencia orange varieties will survive mild frosts (-1°C to -2°C) if protected when young.


In spring and summer, feed with a balanced organic fertiliser. Yellowing leaves indicate a need for more nitrogen.


Oranges and other citrus are heavy feeders that resent close company, so companion plants have to be planted a little way away.


Single Plants: 5,00m (16' 4") each way (minimum)
Rows: 5,00m (16' 4") with 5,00m (16' 4") row gap (minimum)

Sow and Plant

Set out new plants in late winter or early spring. Grow in containers of rich compost to keep plants compact and to make it easy to bring plants indoors for the winter. Good drainage is essential.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.


Prune in spring or summer to shape plants, and watch for thorns. Very sweet oranges need a long season of warm weather, but kumquats, calamondin oranges and satsumas fruit well in marginal areas or when grown in containers.


Pick when richly coloured and fully ripe. Picking can continue for several weeks as fruits do not ripen all at once.


Grow outdoors in the warmer months to expose plants to heat and pollinators. Soft soap sprays can help against scale insects.
