Pest identification
What's eating my red valerian?
Aphids
Signs: Colonies on new shoot tips and flower stems cause slight distortion; rarely severe enough to threaten plant health.
Control: Pinch out affected tips; spray insecticidal soap if colonies are heavy; natural predators usually control populations without intervention.
Vine Weevil
Signs: C-shaped white larvae eat roots especially in containers, causing sudden wilting and plant collapse; adults notch leaf edges.
Control: Apply pathogenic nematodes (Steinernema kraussei) to moist compost in late summer or early autumn; check pots at repotting time.
Rabbits
Signs: Young shoots browsed back to stumps in spring, particularly where rabbits have easy access along boundaries.
Control: Wire mesh guards around new transplants; repellent sprays; established plants typically regrow vigorously after browsing.

Red Valerian pests — FAQ
What is eating my red valerian?
Red Valerian (Centranthus ruber) is highly resilient and rarely seriously damaged by pests. Aphids occasionally colonise soft new growth, and vine weevil larvae can attack roots in containers. Rabbits browse new growth in spring but established plants recover quickly. Overall it is one of the most pest-resistant garden perennials.
