While sensitive to cold and vulnerable to some diseases and insects, citrus trees are not otherwise unduly difficult to care for. Maintaining the proper level of soil moisture is the critical element. During dry periods, check the level of soil moisture several inches down from the surface and water as necessary. A slow, steady drip irrigation is preferable to a rapid watering. However, do not overwater. The area surrounding your tree should be kept clear from weeds and grass. Pruning of citrus trees is generally not necessary except to remove dead wood which is both unsightly and may harbor fungal infections like melanose.
