Hi

I have a Hydrangea which still has dead heads on it should I remove them
now
the buds are coming through?
Cut back to a bud but not too far. If there is a late frost this bud will
possibly get killed so you can then cut back further to another bud.

Also I believe to make them flower blue they need certain soil
conditions,
is there
anything I can do to help this?
Don't know what it's called but you can get something to water on them. I
think it's just the pH that causes the colour.
