Hi. My Thuja Plicata ATROVIRENS hedges are browning. Planted in May, are young hedges about 1m high. Should I cut out the brown leaves? What can I do to stop the browning please?

You can prune out some of the brown, but do not cut back to the bare trunk or branch. I would, also, treat with a copper-based fungicide. I suspect that this is Twig or Leaf Blight. Both will require anti-fungal treatment.
