Urgent - can I save this rhododendron?

This bush is of huge sentimental value to my daughter, as she and my late husband bought it  together before he died five years ago. I've been away for a few weeks, and of  course, wasn't expecting a heatwave while I was gone. I desperately want to save it, as she'll be distraught to lose it. 
Any ideas? I'm assuming it's lack of water, but I might be wrong of course.

    I think your assumption is right Sarah.
    Plenty of water needed - I won't bother saying rain water is best for obvious reasons.
    Give it about 4 gallons ASAP if you haven't already.
    Ideally, let tap water stand for about 24hours to let the chlorine gas-off, so give it some straight now, and get another ready for tomorrow. After that a couple of gallons every other day while were still hot

  • Thank you. I've given it a couple of big drinks over the last week. initially
     I thought it was responding, but now it looks worse.

    I'm going to attempt to take a cutting, in case having an offspring will help my daughter come to terms with this possible loss. But the rooting hormone I've just bought says it's not suitable for ericaceous plants. Any advice on trying to get a cutting to root (or whether there's another formulation I could use) would also be appreciated. Thanks.

    Agreed water water water. I have a similar crisis in a rhodo, in fact even worse, I have done the following dug it up (inadvisable really) put it in fresh ericacious soil, use water butt water to water it, keep the soil wet. Add some sulpher pellets to give it an acid boost - dependent on soil.  I can't tell you if it works yet... but this is my version of cpr

    Me too - I have a little Arctic Tern rhodo looking very sad.
    I lifted it and potted in ericaceous compost and giving it just rainwater. It's not got any worse, but no sign of growth yet.
    I'll persevere with it until next spring

    I've never tried rhodo cuttings, but some info here from the RHS

    In very severe cases like yours , Rhododendrons can be cut to within six-inches of the ground .
    Normally they're pruned after flowering or severely lowered during the Winter months ; however with yours (and it's probably still losing any moisture it might retain), I would bite the bullet and do it .
    You'll lose flowers for maybe a few years , but the root should survive if kept moist and put in a cool shady position . Just noticed it appears to be in the ground ; same rules apply though .
    People place them in full-sunshine , when they prefer coolnesss and dappled shade ; they're forest dwellers originally .
    Go on , be brave ! Having sentimental value to yourself and your daughter , this strikes me as the only alternative to (hopefully) save your plant .

    Good luck !! ;)

    We had the same, the plant seemed to die overnight We cut back everything except two shoots that looked ok. If you gently tug branches that are lying in the ground you may find some that have self rooted. If so cut these with a clean sharp knife and plant elsewhere
    Have you drenched it with vine weevil killer? A definite to do.  We then feed it with an ericaceous liquid feed   A bit of the plant has survived and the rooted stems taken are in a separate hospital plot where everything is carefully watched. They will stay there for a year 

    This years very hot weather has made it a shorter flowering season than usual
    good luck

    Thank you so much for the helpful responses so far. I never thought I'd be posting on this site (my parents' gardening genes skipped a generation!) but I'm so glad that google led me here. 
  • Amidst the devastation, there appear to be some healthy looking leaf buds opening up. Should that give me reason for hope?



  • Pete.8Pete.8 Posts: 11,340
    I very much think so! where there's life there's hope.
    As said above they're very tough plants and they're doing all they can to survive by loosing leaves to protect the roots.
    I was considering chopping mine right back too (as suggested above), but as mine still has a few bits of green here and there I'm going to wait until I see something happening and I won't do anything drastic until next spring by which time I will either have started to recover  - or not...

    I cut out all the obviously dead bits and I'm leaving it in a shady sheltered spot
