How to Grow an Orange Plant: A Complete Guide

How to Grow Orange Plant?

To grow an orange plant, you need to provide warm and moist soil enriched with organic matter.

If you don’t have suitable outdoor conditions, you can grow oranges in containers by grafting them onto a dwarfing rootstock.

They need a sheltered spot with full sun during spring to fall, but should be moved indoors in winter as they cannot tolerate frost or temperatures below 7°C (45°F).

Feed oranges with a balanced organic fertilizer in spring and summer, and look for yellowing leaves indicating a need for more nitrogen.

Make sure to give them enough space, as they are heavy feeders, and plant them at least 16′ 4″ (5.00m) apart.

Good drainage is essential, so set out new plants in late winter or early spring.

Prune in spring or summer to shape the plants and watch out for thorns.

While sweet oranges require a long season of warm weather, other varieties like kumquats, calamondin oranges, and satsumas can be grown in marginal areas or containers.

Pick oranges when they are fully ripe and richly colored, and continue picking over several weeks as fruits do not ripen all at once.

During warmer months, grow outdoors to expose the plants to heat and pollinators.

In case of scale insects, use soft soap sprays to combat them.
