What is causing brown patches on my conifer hedges?
Our Advice
It sounds like your conifers are being attacked by cypress aphids. The damage shows as brown patches of dead foliage in the hedge. Sprays of Organic 2 in 1 (Vitax) or Resolva Natural Power Bug Killer (Westland) will control this pest. Spray around the edges of the dead patches, where the aphids will be to survive the winter.
