🌱 How to Care for Oxford Ragwort to Prevent Aphids?

💧 How to Water

Water sparingly, approximately once every 7–10 days. Oxford Ragwort is highly drought-tolerant and evolved on dry volcanic rock; its biggest enemy is waterlogged soil, which quickly leads to root rot. Allow the soil to dry out almost completely between waterings. In winter or during rain, reduce frequency further.

☀️ Lighting

Oxford Ragwort demands full sun — at least 6 hours of direct sunlight daily. It thrives in bright outdoor positions: sunny borders, gravel gardens, walls, or containers on south-facing aspects. Insufficient light causes leggy, weak growth and reduced flowering. This is not a shade-tolerant plant.

🪴 Ideal Soil

Choose a gritty, free-draining compost or mix standard potting soil with plenty of perlite or grit. Oxford Ragwort naturally colonises rocky, nutrient-poor ground and performs best in lean soil with a pH of 5.5–7.5. Avoid heavy, moisture-retentive mixes; good drainage is non-negotiable.
