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 spring to fall. In winter, plants may be moved into a greenhouse, sunroom, or heated garage.

Frost tolerant

No. Grow at temperatures above 7°C (45°F).


In spring and summer, feed with a balanced organic fertilizer. 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: 16' 4" (5.00m) each way (minimum)
Rows: 16' 4" (5.00m) with 16' 4" (5.00m) 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 personalized 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 colored 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.
