Yes, you can prune a potted naval orange tree before bringing it inside for the winter. Trim away any dead or overgrown branches to promote healthy growth. Once indoors, place the tree near a sunny window, ideally receiving 8 hours of sunlight daily. Water it when the top inch of soil feels dry, but avoid overwatering. Maintain a consistent indoor temperature between 55-70°F (13-21°C) and consider using a humidifier, as indoor heating can dry the air. Fertilize sparingly during the winter, and monitor for pests. Pruning and these simple care steps will help your potted naval orange tree thrive during the colder months indoors.
