ðą How to Care for Blanket Flower to Prevent Leafminers?
ð§ 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.
âïļ 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.
ðŠī Ideal Soil
Prefers well-drained, sandy, or even poor soils. Avoid heavy clay or waterlogged soils. Does not require rich or amended soil â in overly fertile ground, it tends to produce lush foliage with fewer flowers.
