Cocoon Worms on Rose Leaves: Nutrition-Based Pest Control

Photo shows cocoon-type worm on leaf undersides. Many insect types do this; root cause is plant nutrition.

Solution: Organic Nutrition + BT

• Feed with good organic rose fertilizer (broad nutrition)
• Avoid high nitrogen chemical fertilizers
• Spray BT (Bacillus thuringiensis) to stop chewing
• Prune damaged areas; promote new growth

Healthy, organically-fed roses resist pests naturally.
