Viburnum leaf problem

  I don't know, but I'd guess at 2 possibilities.
  Sunburn - I also had viburnum davidii and found it performed better in a shadier part of the garden. It is a beautiful shrub - especially if you get berries.
  The leaves covered in tiny spots could indicate spider mites, but it would be a massive infestation to cause such damage.
  If it is spider mites, you'll see lots of very small webs toward the top of the plants and if you look at the underside of an affected leaf with a magnifying glass you should be able to spot them.

  Hi Pete.8, I couldn't see any spider mites but I'll take another look just in case.  I did think it had to be the recent heat but it's the weird silveryness to the browning that put doubts in my mind.  I would have expected the leaves to just turn brown and crispy.  These still have substance to them rather than crispy dry.  But perhaps that's what davidii does, the leaves are quite meaty to start with.

  Yes, it's because the leaves are quite thick and waxy that they don't droop in the heat/sun.
  The shrub is probably OK but will likely loose all the affected leaves over winter.
  You can trim it up in the spring if there are any dead bits, but it should regrow OK next year - weather permitting
