I cut mine back last year to near floor level.It had new growth buds at the
time and it soon grew back with abundance. The pink and blue are to do with
how acidic the soil is I believe but I might be wrong. Im in the leeds area
and my Hydangea is pink.

Hi

I have a Hydrangea which still has dead heads on it should I remove them
now
the buds are coming through?

Also I believe to make them flower blue they need certain soil conditions,
is there
anything I can do to help this?

Thanks Ian
