I've never been good at describing soil! The pH is quite neutral so I added
ericaceous compost in the planting hole and generously around the top of the
plant. I've also watered it directly a couple of times with an ericaceous
water-soluble fertilizer as I thought the soil might not be acidic enough.
Perhaps I did too much and have burnt it?

It's not so much that rhododendrons are desperate for a low pH, more
that they can't take up iron in a high pH soil. If you're on the acid
side of neutral you should be OK.


It's in the front garden so it gets sun until early/mid-afternoon and
complete shade in the evening. It's not really protected from wind, but
then isn't stuck out on its own either.

If you can't feed a sick plant, what can you do for it?

Usually (particularly if its in a pot) - let its roots dry out a little
;-)
Sometimes - give it more water - though if you are getting major
problems from lack of water it's usually too late.

Other than that - it's what you'd do for a human - find out what's wrong
then treat the cause, or at least, the symptoms.
