Care for a Texas sage bush by planting it in a sunny location, using well-drained soil and watering it rarely. Prune the plant for size and shape in the late winter or early spring.
Texas sage can be propagated or grown through seeds, cuttings or young plants. For seeds, press them shallowly into moist soil, and wait a month for germination. To grow Texas sage through a cutting, cut a 4-inch piece from an adult sage bush in the winter, and place it in well-drained soil. If growing sage in a pot, choose a smaller variety such as the compacta. Other cultivars can reach up to 8 feet tall.
After choosing a propagation method, select a location that receives full sun and has well-draining soil, preferably soil amended with perlite and sphagnum moss to improve drainage. Rocky and gravelly soil works is also ideal. Avoid adding compost or fertilizer to the soil, as the Texas sage plant thrives in poor soil conditions.
Because Texas sage is drought resistance, water it sparingly during the summer to prevent root rot. Cease water entirely during the winter to allow the plant a period of dormancy. During the late winter or early spring, prune back scraggly and dense foliage to help the plant maintain the desired side and a round shape.
