Answer: Citrus trees are delightful indoor plants during the winter months and will produce fragrant flowers followed by small fruit if growing conditions are right. Your tree will require average household temperatures (minimum 50F in winter), careful watering, regular feeding, and freedom from drafts. The trees are self-fruitful but you can help things along by hand-pollinating the flowers, transferring pollen with a soft brush. Provide as much light as possible by choosing the sunniest site you have. (Supplement low light conditions with fluorescent gro-lights.) Air tends to be dry indoors during the winter. Mist the leaves every few days to counteract dry air. Water often enough to keep the soil moist but not soggy wet, and feed monthly with a half-strength dilution of liquid fertilizer. Take your tree back outdoors when the weather warms in late spring.
