Rhododendron and Azalea wilting

Hi.  I expect everyone has noticed the wilting leaves of rhododendrons (both large and small) and azaleas following the unusually high temperatures (and drought) we've been suffering from over the last few months.  Can anyone suggest what can be done to save them?

    Have you been giving them a good soak?
    Are they in pots or in the ground?  If the former, submerge the pot in water until there are no bubbles coming up.

    They are not deep rooted, the roots are shallow and very near the surface...these must be protected.

    Mulch, mulch and more mulch in a huge circle round each one...
    after you have given each gallons of water .. not just a tiny dribble.
    Composted bark is good or leaf mould.
    At least 4" deep...but not touching the trunk.

    They really prefer dappled shade.
     Hate full sun/exposed /windy spots.

    We have learnt a lot over the years here! These plants naturally drop some leaves at this time of year but they also set the flower bud for next so we always feed after we have given a drench of nematodes or some other wine weevil deterrent 
    take photos so you can monitor and remember to date!
