Water: Citrus plants like consistent moisture but not waterlogged soil. For example, move your plant to a partially shaded area outdoors after the last frost in spring, and gradually move it into more light over a period of two weeks. Acclimate your plant gradually when you move it outdoors/indoors. In the spring after the danger of frost has passed, place your citrus tree outdoors to receive the maximum amount of sunlight – 8-12 hours of direct sun exposure – and move it back indoors in the fall, prior to the first frost. Supplemental indoor lighting with a fluorescent or LED grow light will be necessary if ambient light is insufficient.
During the winter, a position near a South-facing window will provide the strongest light. Light: Place your citrus plant where it will receive at least 6 hours of direct sunlight or preferably more (8-12 hours) each day.
