Pest identification
What's eating my narrow-leaf coneflower?
Aphids
Signs: Soft colonies on young flower stems and buds cause distorted growth and sticky honeydew deposits.
Control: Spray with insecticidal soap or a strong water jet; encourage ladybirds; avoid high-nitrogen fertiliser that promotes lush soft growth.
Japanese Beetle
Signs: Adults skeletonize petals and leaves, leaving a ragged, brown appearance across flower heads in midsummer.
Control: Hand-pick beetles into soapy water in the morning; apply kaolin clay to foliage; avoid pheromone traps near plantings.
Rabbits
Signs: Clean browsing of young spring shoots and flower stems down to near ground level, particularly on new transplants.
Control: Surround plants with a low wire mesh cylinder in spring; repellent sprays on emerging foliage; established clumps are usually not threatened.
