🌱 How to Care for Redstem Filaree to Prevent Powdery Mildew?
💧 How to Water
Water moderately and only when the soil has dried out—Stork's-bill tolerates short dry spells much better than waterlogged soil. Once established, natural rainfall is usually sufficient.
☀️ Lighting
Choose a sunny to full-sun location with at least 6 to 8 hours of direct light; the plant blooms significantly less in partial shade.
🪴 Ideal Soil
A well-draining, sandy-loam to stony soil with a neutral to slightly alkaline pH (approx. 6 to 7.5) is ideal. Nutrient-rich, humus-heavy soil is not necessary—Redstem Filaree actually grows better in poor soils.
