rhododendron emergency
 

Just came back from a week's holiday to find one of the overflow pipes
(central heating or hot water tank, I don't know which) dripping into
a potted rhododendron.

I suspect the water's got a lot of lime in it because there's white
stains all over an adjacent window, and the rhododendron's looking
very sick now -- all dried out, with all the leaves either curling
outwards or yellow.

I've put some coffee grounds around it and watered it with a solution
containing a couple of teaspoons of vinegar, to try to get the acidity
back up. Any other ideas? The plant must be at least 10 years old (I
acquired it from a relative) and is about 5 feet tall.
