acidity etc. but I'm not quite sure if the ground will be damp enough
for them. Although there is a lot of humus the underlying ground is
sandy and well drained so it's relatively dry and rainfall is low
(we're in Suffolk) - though you might not think so just at the moment!

So, will rhododenrons be OK?
I, and plenty of my neighbours, grow (small) rhodies on dry stony ground in the Chilterns, fortunately not chalky where we are, but we sit in a small local micro-climate that has lower summer rainfall than most places in the Chilterns. I water them in dry weather (last year I was watering in Feb, very pleased with this winter's rainfall), and mulch the soil with bark to reduce water loss, and use special acid plant fertiliser, and scatter a bit of ferrous sulphate once a year to keep up the acidity.

Sandy soil with plenty of humus sounds ideal if you are prepared to water them in dry spells. They flower best if well fed - feed them especially just after flowering to recover their energy, and remember their flower buds build during winter. I have a couple of early flowering ones which need fleecing if frost threatens just before flowering time. I have found the evergreen and semi-evergreen types do better for me, perhaps the tougher leaves loose less water.
