Iowa Golden Saxifrage

Blue Mustard is a drought tolerant plant, so water this species moderately. Water deeply and thoroughly once every 2 weeks during the spring and summer growing season. In the late summer, reduce water frequency and allow the soil to dry out between watering to encourage the plant to go dormant. During the winter months, reduce watering frequency as much as possible, and only water if the top inch of soil feels dry to touch.

Blue Mustard prefers full-sunlight in order to thrive, and should be placed in direct sunlight for at least 6 hours per day. Blue Mustard tolerates a bit of shade, but it will flower less without full-sunlight. It should be grown in a sunny spot with well-draining soil. During the growing season, which is spring to summer, it is best to give Blue Mustard at least 8-10 hours of sun each day for optimal flower and foliage development.

Blue Mustard (Chorispora tenella) should be pruned after flowering, during late spring or early summer. Pruning should focus on removing spent blossoms as well as any overly long or straggly stems. Blue Mustard can be lightly pruned to shape the plant as needed, though too much pruning will reduce its flowering.
