Cultivating a Meyer lemon tree indoors is quite easy. Some dwarf varieties exist to make the job even easier. As long as your house is usually between 65 and 85 degrees Fahrenheit, Meyer lemons will be quite happy. If you live in an area with cold winters and hot summers, you may even want to bring your Meyer indoors over the winter and put it outside during the summer.
Choose a dwarf variety of Meyer lemon to grow indoors for best results.
Plant your Meyer lemon in a 10- to 15-gallon container. Mix potting soil mix with wood chips to ensure adequate drainage. Just barely cover the root ball with dirt so you do not encourage trunk rot.
Apply citrus-specific fertilizer as the manufacturer directs.
Insert a moisture meter into the soil in your Meyer's pot. This will take the guesswork out of figuring out when your tree needs water.
Keep your Meyer in an area that gets full sun for at least six hours per day, and preferably eight to 12. If this is not possible, you may want to invest in grow lights for your Meyer's continued good health.
Adjust the thermostat in your house so it is between 55 and 85 degrees Fahrenheit. This will encourage the Meyer to be at its best.
