For optimal growth, plant Epimedium X 'rubrum' in a shaded or partially shaded area with well-drained, organic-rich soil. Ensure consistent moisture by watering regularly, particularly in dry periods. Apply mulch to conserve moisture and reduce weed competition. Prune back old leaves in late winter or early spring to allow new foliage to emerge. Use a balanced, slow-release fertilizer in spring to promote robust growth and flowering.
