Conditions for Halesia monticola

[Andy Phillips]

I have a Halesia monticola (snowberry) in my garden (Bristol, England), 
that has never looked very happy. The leaves are very pale green, with a 
yellow margin. My best guess is that it doesn't like the soil type - 
my soil is well-cultivated clay over coal measures, about pH 6.5-7. Does 
anyone know the pH optimum for this plants, or any other suggestions for 
cheering it up?

Thanks

Andy Phillips
