Common Dusty Miller Problems
Dusty miller plants may suffer from root rot if overwatered, especially in clay soils. To prevent this, plant them in well-drained soil or containers. Slugs are also common pests, but handpicking or using beer traps can control them. Raised beds or pots help reduce these issues and keep the plants healthy.

Frequently Asked Questions About Dusty Miller Problems
Why are my dusty miller plants drooping?
Drooping in dusty miller can be caused by both underwatering and overwatering. To check if your plant needs water, feel the top 1 inch of soil—if it's dry, give it a drink. However, wilting can also be a sign of too much water. Make sure the soil drains well to prevent root rot, which can also cause drooping.
Where is the best place to plant dusty miller?
Dusty miller thrives in full sun but can tolerate partial shade. In hot, dry climates, a spot with afternoon shade is ideal. Keep in mind that plants grown in heavy shade may have greener leaves and become leggy, losing their signature silvery look. If you're aiming for that striking silver color, full sun is your best bet.
Can you overwater dusty miller?
Yes, overwatering is a common issue for dusty miller. Root rot is a frequent result of excess watering, especially if the soil doesn’t drain well. Water your plant only when the top layer of soil feels dry, and avoid splashing water on the leaves, as this can cause blemishes or fungal issues.
Why is my dusty miller turning brown?
Brown spots on dusty miller are often a result of fungal diseases, typically caused by environmental conditions such as high humidity or poor air circulation. To prevent this, make sure your plant is spaced well, avoid watering the foliage, and remove any affected leaves to stop the spread of the fungus.
