Mealybugs and Pink Mealybug on Hibiscus: Organic Solutions

Mealybugs and Pink Mealybug on Hibiscus: Organic Solutions

Shriveling leaves around flower buds, failure of blooms to open, and a white powdery substance in the flower center are hallmarks of mealybug infestation—particularly the invasive pink mealybug that has spread across the southern U.S. in recent years. These pests suck sap from developing buds, causing distortion and drop.

Organic Management

Atomic Grow, an organic foliar spray, has shown efficacy against mealybugs while improving overall plant health. It cleanses leaf surfaces, raises brix (sugar) levels, and makes plants less attractive to pests. Apply weekly until infestation subsides, then biweekly for maintenance.

Cultural Practices

• Prune heavily infested branches and dispose of them.
• Encourage natural predators like lady beetles and lacewings by avoiding broad-spectrum insecticides.
• Inspect new plants carefully before introducing them to your garden.
