Water: Douglas Iris thrives in coastal habitats, preferring moderate moisture and tolerating fog. It requires consistent hydration with regular weekly watering. As an evergreen, douglas Iris retains foliage year-round, necessitating careful watering during the growing season to maintain its health and vigor.

Fertilize: For optimal growth, douglas Iris needs balanced fertilizers in early spring and high phosphorus before blooming. Fertilize every 4-6 weeks during active growth, adjusting frequency in fall and winter. Always water douglas Iris after fertilizing to enhance nutrient absorption and prevent root burn.

Pruning: Douglas Iris features vibrant blooms and strap-like leaves, thriving in temperate climates. Prune in early spring to late winter for optimal growth. Trim flower stalks post-bloom to prevent seed formation. Avoid cutting foliage before it dies back to support growth and vigor.

Propagation: Douglas Iris is a perennial herb native to western U.S. grassy woodlands, thriving in well-draining soil and partial shade. Propagate by dividing rhizomes post-flowering, ensuring each section has roots. Plant rhizomes at previous depth and space for growth. Water regularly until establishment.
