A citrus tree may be the ideal houseplant for a warm sunny room. Their shiny, dark green leaves and fragrant blossoms add to the appeal of their brightly colored, ornamental fruit.

Citrus trees need fast draining, fertile soil. They require 5-6 hours of sunlight. Feeding with a high-nitrogen, acid fertilizer should be done in late winter, June and August. In return for this minimal required care, you will be rewarded with continuous, year-round fragrant blooms and fruit.

When grown outdoors in favorable conditions, trees grow to 20 feet or higher. Indoors, they may be kept at four to five feet.
