🌱 How to Care for Common Blanketflower to Prevent Leafminers?

💧 How to Water

Water deeply but infrequently. Soak the root zone at planting and while the plant establishes, then switch to occasional deep watering only during extended dry, hot spells — soggy soil invites root rot.

☀️ Lighting

Plant in full sun with at least 6 hours of direct light daily. Too much shade causes leggy growth and fewer flowers.

🪴 Ideal Soil

Use loose, well-draining soil such as sandy or rocky garden soil. Avoid heavy clay and rich, constantly moist beds; a neutral to mildly alkaline pH is ideal.
