🌱 How to Care for Narrow-leaf Coneflower to Prevent Aphids?

💧 How to Water

Water deeply once a week during the first growing season to help the taproot establish. After that, water only during prolonged drought — established plants tolerate dry spells well and are prone to crown rot if kept too wet. Always water at the soil level rather than overhead, since wet foliage encourages fungal disease.

☀️ Lighting

Give it full sun — at least 6 hours of direct light daily. It tolerates light afternoon shade in very hot climates but blooms best and grows most compactly in full sun; too much shade causes floppy, sparse growth.

🪴 Ideal Soil

Use lean, light-textured, well-draining soil such as sandy or gravelly loam with a near-neutral pH (around 6.0-7.0). Rich, heavily amended, or poorly drained soil leads to weak growth and root disease — this prairie native actually performs best in average to poor soil.
