Look out for coral spot

13th March 2020

Look out for coral spot in your shrubs before they come into full leaf. Nectria cinnabarina is a fungus that feeds on dead wood and can overwinter on overlooked prunings and old hazel peasticks. Spores from the pink pustules on the bark are dispersed in rain splash and wind-blown rain onto living woody tissue, and if a plant is already stressed infection may take hold.
