ðą How to Care for Silver Spurflower to Prevent Spider Mites?
ð§ How to Water
Once established, water when the top few centimetres of soil are dry, usually about once a week in warm weather. Containers need water more often than plants in the ground. Never leave the soil soggy or water in the saucer, and avoid wetting the leaves late in the day, which encourages powdery mildew.
âïļ Lighting
Full sun to part shade. More light gives more silver foliage; in very hot climates, choose a spot with afternoon shade.
ðŠī Ideal Soil
Not fussy about soil type or pH, but it needs good drainage. In containers use a light, fast-draining mix; avoid heavy, wet ground.
