Mealybugs

These small insects secrete a white, waxy, cottony substance to protect themselves. In miniature roses, they tend to cluster around the leaf axils and tender new growth.

Hard Water Deposits (Mineral Buildup)

If you are using tap water high in calcium or magnesium, white crusty deposits can form on the leaf surfaces as the water evaporates.

Common
