Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water sparingly, allowing the soil to dry out completely between waterings. Overwatering is a common cause of root rot, especially in containers. Reduce watering significantly during winter dormancy.
Ensure good drainage to prevent waterlogging.
Prune Dusty Miller in spring to encourage bushier growth and maintain its desired shape. Remove dead or leggy stems to promote vigor and prevent it from becoming straggly.
Pinching back the tips of young plants also encourages a more compact habit.
Easily propagated from stem cuttings taken in spring or summer. Dip the cut end in rooting hormone and plant in well-draining potting mix. Keep moist and in a warm, bright location.
Cuttings typically root within a few weeks.
Repot Dusty Miller annually or every two years in spring, especially when grown in containers. Choose a pot that is only slightly larger than the current one and ensure it has drainage holes.
Use a well-draining potting mix to prevent waterlogging.
