Hello Adrienne, A recent trip to southern Spain has left me enamored with pretty, fragrant orange and lemon trees. I realize our climate is too cold to permit outdoor cultivation of orange trees here, but I was wondering about growing them indoors, maybe even from a seed. I have a top floor apartment with direct sunlight, SW exposure and a large window. The superamrket varieties all would be large-sized, outdoor types, which take many year to mature and do not bloom or fruit indoors. You also will find plants at your local nursery or garden center.
Citrus lends itself well to indoor cultivation with very little trouble.
Barring that, a sunny, sotuhwest window should be fine, as long as plants get plenty of light. My soil is mostly clay. To the soil add compost or manure, work it in well and dig a large hole at least three feet in diameter. Purchase a potted fig, go for Brown Turkey. Mulch ans keep weeds from encroaching.
