For the genus owenia, select well-draining soil and a site with full sun to partial shade. Water needs are moderate, with importance on allowing soil to dry out between watering. Planting begins by amending the soil for better drainage if necessary, then dig a hole twice the width of the plant's root ball. Place the owenia at the same depth it was in the container, backfill gently, and water thoroughly. Mulch around the base to retain moisture. Monitor water and soil conditions, considering local climate as owenia have varied species-specific requirements.
