    One of my hedge trees, and my neighbour's tree, both arborvitae (emerald green), are both turning brown.(see photo) Could this be spruce spider mite? Is this a common problem in the lower mainland (North Vancouver)?

    Look at the damage up close, maybe even using a lens, to see if there are mites.
