Brooklyn Botanical Garden in its Plants & Gardens News Volume 19, Number 3 | Fall 2004/Winter 2005 published an article by Scott D. Appel about growing citrus indoors:

"...Citrus are easy to cultivate indoors. Plant seeds immediately upon removal from fruit—contrary to popular belief, the seeds don't like to dry out. Start with a small pot and transplant the young plants as needed. Seedlings will need plenty of water, but don't let them sit in a saucer of excess runoff: Citrus hate wet feet. Use a compost-rich, well-draining, slightly acidic soil (about 5.5 to 6.0 in pH). Employ an acidifying fertilizer made specifically for citrus, as these plants have particular requirements for micronutrients that most fertilizers don't contain. A very sunny, cool window is the ideal location for cultivating your citrus.

Citrus trees grown from seed rarely flower and produce fruit. However, their fragrant leaves can be dropped into hot bathwater to impart a wonderful perfume. They can be added to stuffings, stews, and roasts or placed within the cavities of fish and fowl to add a delightful citrus flavor. Citrus leaves can be used in Thai stir-fries (leaves of the Kaffir lime, Citrus hystrix, are especially good for this). They can also be placed in the bottom of canning jars to impart a redolent tang to jams, jellies, chutneys, relishes, and marmalades".
