🌱 How to Care for Plains Coreopsis to Prevent Aphids?

💧 How to Water

Water deeply once a week during the growing season. Once established, Plains Coreopsis is drought-tolerant and only needs watering during extended dry periods. Avoid overwatering and waterlogged soil, which can cause root rot.

☀️ Lighting

Plant in a location with at least 6-8 hours of direct sunlight per day. Full sun is essential for abundant flowering. In hot climates, light afternoon shade can prevent heat stress without significantly reducing blooms.

🪴 Ideal Soil

Use well-draining sandy or loamy soil. Plains Coreopsis tolerates poor, rocky, and dry soils — it actually blooms more in lean conditions. Avoid heavy clay soil or areas with poor drainage, as wet roots lead to crown rot.
