🌱 How to Care for Iberian Houseleek to Prevent Curculionidae?
💧 How to Water
Water thoroughly only when the soil has dried out completely, roughly every 2 weeks in warm dry weather for plants in pots, and much less in cool weather. Plants in the ground usually manage on rainfall. Keep it on the dry side in winter and never let the pot stand in water: soft, translucent or rotting rosettes are a sign of too much water.
☀️ Lighting
Give it full sun, ideally in an east, south or west-facing spot. Strong light keeps the rosettes compact and brings out the purple leaf tips; in shade they stretch, turn plain green and flower poorly. It is not a good indoor plant, as it needs bright outdoor light and a cold winter rest.
🪴 Ideal Soil
Use poor to moderately fertile, sharply drained soil: sandy, loamy or chalky ground all work, whatever the pH. In containers, mix equal parts loam-based, peat-free potting compost and grit, and top-dress with gravel so the rosettes sit dry.
