Frequently Asked Questions


What’s a common pest or disease on Echinacea purpurea (Purple Coneflower) and how can I fix it?
Powdery mildew is a frequent issue on Echinacea, especially in humid weather and crowded plantings. Improve airflow by spacing plants (about 18–24 inches) and water at the base in the morning to keep leaves dry; if spots appear, remove heavily affected leaves and consider an application of a labeled fungicide for powdery mildew on ornamentals. Avoid overhead watering and don’t fertilize late in the season, which can encourage tender, mildew-prone growth.
How often should I water Echinacea purpurea during peak growth?
During active growth (spring through early summer), keep the soil evenly moist but not soggy—water when the top 1 inch of soil feels dry. Echinacea is drought-tolerant once established, so after the first season you can reduce to deep watering only during dry spells. Aim for about 1 inch of water per week from rainfall plus irrigation, adjusting for heat and wind.
How do I know when PowWow White Echinacea purpurea is ready to harvest?
Harvest cut flowers when the ray florets (the white “petals”) are fully open and the central cone is firm and not yet brown and dried. For longest vase life, pick in the morning after dew has dried but before midday heat. With typical timing around 70 days from sowing/transplanting, check flower maturity daily once buds form.
