🌱 How to Care for Purple Coneflower to Prevent Aphids?

💧 How to Water

Water new plants deeply once or twice per week during the first growing season. Once established (after year one), Echinacea is drought-tolerant and needs watering only during extended dry spells (every 2 weeks or less). Avoid overhead watering to reduce disease risk.

☀️ Lighting

Purple Coneflower thrives in full sun with at least 6 hours of direct sunlight daily. In very hot climates, light afternoon shade is acceptable, but deep shade will cause leggy growth, weak stems, and reduced flowering.

🪴 Ideal Soil

Prefers average, well-drained soil. Tolerates poor soil, clay, and sandy conditions as long as water does not pool around roots. Does not require rich, fertile soil — overly rich soil leads to weak, floppy stems. A slightly acidic to neutral pH (6.0-7.5) is ideal.
