Hydrate your tree with 1/4 to 1/2 gallon of water every five to seven days to keep the soil moist. Make sure that your tree does not become waterlogged.
Provide eight to 12 hours of sunlight a day for your indoor lime tree so that your tree blossoms and eventually produces limes. Use full-spectrum fluorescent grow lights to help meet this daily requirement.
Make sure the room temperature that your lime tree is in does not fall below 55 degrees Fahrenheit or go over 85 degrees Fahrenheit. Keep your thermostat above 65 degrees Fahrenheit for best results.
