🌱 How to Care for Dusty Miller to Prevent Spider Mites?

💧 How to Water

Water deeply, then let the top 3-5 cm of soil dry out completely before watering again — roughly every 10 days outdoors in mild weather, more often in intense heat or containers. Always water at the base; wetting the fuzzy leaves washes away their silvery coating and invites fungal problems.

☀️ Lighting

Give it at least 6 hours of direct sun daily for the tightest, silvery growth. It tolerates partial shade, but plants stretch and turn greener with too little light. In scorching climates, light afternoon shade prevents leaf burn.

🪴 Ideal Soil

Plant in sandy or gravelly soil with excellent drainage; amend heavy clay with perlite or coarse sand. Dusty Miller tolerates poor, lean soil far better than rich, moisture-retentive mixes, which invite root rot.
