light
Citrus love bright sunshine, preferably 8-12 hours per day. Indoors, place in a South facing window. During short winter days, supplement with a grow light.
soil
Plant in an all-purpose potting soil with added organic matter such as compost or worm castings.
water
Water when the top 2-3 inches of soil are dry. Cut back on watering in the winter to avoid root rot. Do not allow to completely dry out.
fertilizer
Feed every two to three weeks during periods of active growth and every four to six weeks during dormancy. Use a citrus-specific fertilizer.
tips and troubleshooting
Citrus are susceptible to several pests, especially in the winter. Check regularly for signs of spider mites, scale, and mealy bugs.
Keep horticultural oil and insecticidal soap to treat as needed.
