🌱 How to Care for Blanket Flower to Prevent Septoria Leaf Spot?

💧 How to Water

Water every 7-14 days, allowing the soil to dry out completely between waterings. Blanket flower is very drought-tolerant and is more likely to suffer from overwatering than underwatering. During heavy rains, ensure the soil drains well to prevent root rot.

☀️ Lighting

Plant in full sun with at least 6-8 hours of direct sunlight per day. The more sun it receives, the more abundantly it will flower. In partial shade, the plant grows but produces significantly fewer blooms.

🪴 Ideal Soil

Prefers well-drained, sandy, or even poor soils. Avoid heavy clay or waterlogged soils. Does not require rich or amended soil — in overly fertile ground, it tends to produce lush foliage with fewer flowers.
