Growing Achillea 'Coronation Gold' begins with planting it in well-draining soil and a sunny location to encourage robust growth and prolific flowering. This perennial is highly drought-tolerant once established, so it requires minimal watering; deep watering during extended dry spells will enhance bloom production. Regular deadheading of spent flowers will promote continuous blooming throughout the season. In late fall, cutting back the plant helps maintain its shape and health. Additionally, dividing the clumps every few years prevents overcrowding and revitalizes the plant, ensuring it remains vigorous and attractive in the garden.
