Watering:
Lime trees require moist soil and should be watered on a regular but not obsessive basis.
Fertilizer:
From spring to summer, fertilize lime trees every three weeks with a citrus-specific high-nitrogen fertilizer.
Re-potting:
Repot in the spring before active growth begins. They can, however, be re-potted at any time during the summer. They do not need to be replanted every year.
Temperature:
They can only survive in temperature above 10 degree Celsius.
