You can grow Mandarin oranges in pots just like other types of citrus. Move the pots outdoors in full sun for the growing season and bring indoors before freezing weather arrives. Winter them in a sunny window and provide a little humidity. Your Mandarin orange will produce fruit in late winter.
Instructions
1. Plant your Mandarin orange. First put a layer of rocks or gravel in the bottom of the pot to help water drain away from the roots. Add enough potting soil so that when you put the Mandarin orange into the pot, the surface of the transplant is about 2 inches below the edge of its new pot.
2. Water thoroughly, until it drains out of the bottom of the pot.
3. Feed your Mandarin orange weekly with a water-soluble fertilizer applied at half the strength recommended by the manufacturer.
4. Move the plant outdoors during the frost-free weather of your growing season. Put in full sun and check daily to see if it needs watering.
5. Move your indoors when freezing weather arrives. Put in a sunny, south-facing window in a cool room. Citrus do best indoors growing at temperatures in the mid- to upper 60s. Provide extra humidity by using a humidifier near the tree. Or group plants near it to increase the humidity.
6. Prune in late winter. Cut back the main branches by about a third every other year to maintain it at a size suitable for growing in a pot.
