🌱 How to Care for Shrubby St. John's Wort to Prevent Grey Mould?
💧 How to Water
Shrubby St. John's wort is a drought-tolerant plant. After planting, it should be watered weekly until it becomes established, but once rooted, watering every 10 days is sufficient. Avoid constant moisture, as root rot can occur in waterlogged soil. Deeper watering is necessary during dry periods in the summer.
☀️ Lighting
Full sun (6+ hours per day) ensures the best flowering and the most compact habit. It also tolerates partial shade, though with reduced flowering. In shady locations, it tends to become leggy and flowers poorly. Open south- or east-facing locations are ideal.
🪴 Ideal Soil
It requires well-draining soil, although it has a wide tolerance for soil types—it thrives in sandy, loamy, and clay soils alike. It is flexible regarding soil chemistry, performing well between pH 5.5 and 7.5. Fertilized, rich soil is not necessary; poor, drier soil is also suitable.
