Scale Insects on Desert Rose: Identify, Treat, and Adjust Care

The light spots on your desert rose are scale insects, not a fungus. Each spot is a scale feeding on sap; heavy infestations cause yellowing and leaf drop.

Treatment Options

• Apply an insecticide labeled for scale insects.
• Or try Atomic Grow, an organic product that strengthens the plant and repels pests while promoting blooms.

Water and Light Adjustments

In hot climates, water more frequently—light watering 2–3 times a week is better than infrequent deep watering for container plants. Also, 4 hours of intense afternoon sun may be excessive; consider moving the pot to a spot with morning sun and afternoon shade.
