Winter Care for Ornamental Orange Tree: Light, Temperature, and Watering

The Dilemma

Citrus needs cool winters (40–60°F) AND full sun. Garages provide temperature but not light. Grow lights (12 hrs/day) work but are costly unless fluorescent tubes are used close to the tree.

Best Compromise

• Cool, bright room (sunroom, enclosed porch) if available.
• Otherwise, garage + fluorescent shop lights 6″ above canopy, 12 hrs/day.
• Water sparingly—let soil dry deeply between waterings.

Spring Transition

Move outdoors after frost, acclimate gradually to full sun. Resume regular watering and fertilizing.
