Best advice is to look in gardens close to yours - can you spot healthy
rhodos or other acid loving plants?

No, my neighbour has the usual conifers, bulbs and pyracanthas,
nothing interesting at all really. I just have a hankering for some
flowering shrubs. I have a beautiful ceanothus in my front garden,
but the blue flowers are so small. I think I'll take your advice and
buy a soil testing kit and take the opportunity to defrost the freezer
while I'm about it.

I'll let you know what happens.

Thanks.
