What's eating my blue bird rose of sharon?
Japanese beetle (Popillia japonica)
Signs: Feeding groups skeletonize leaves and chew through blue flowers; heavy infestations in July–August can strip plants of foliage and blooms entirely
Control: Hand-pick into soapy water each morning during peak season; apply neem oil as a deterrent; avoid pheromone traps near this plant as they attract more beetles than they catch
Aphids
Signs: Distorted, sticky new growth and flower buds; sooty mold on honeydew deposits; ants protecting colonies are a giveaway
Control: Hose off with water; apply insecticidal soap or neem oil spray; plant insectary flowers nearby to support aphid predators
Deer
Signs: Browsing of flower buds and open blooms; repeated feeding prevents the ornamental display from developing fully
Control: Use repellent sprays applied every two to three weeks through the blooming season; cage young plants with wire fencing until established and large enough to outgrow browse height
