CARE FOR KAFFIR LIME Despite the fact that Kaffir lime trees are tolerant of less than ideal conditions, there are specific needs that should be met for optimal growth. Kaffir limes prefer full sun in moist, well-drained soil. If grown indoors, keep near a sunny window. The Kaffir lime tree appreciates water and somewhat humid conditions during the growing season. Keep in mind, however, that this tree is prone to root rot if kept too wet, so allow the soil to dry out some between waterings. Regular misting helps with humidity levels. Kaffir lime trees are cold sensitive and need to be protected from frost. Therefore, these plants should be brought indoors during winter if they are grown outside. They enjoy indoor temperatures around 60 F. (16 C.) or above, especially during winter months. Prune the lime tree while young to encourage branching and a more bushy plant.
