Hi all,
I split and re planted last autumn a Hydrangea bush that was
originally from my late father's garden, so it is plants' that are of
emotional and general value to me.

They have put on good growth this year but not flowed, nor did I think
they would.
Should I cut the new growth back this autumn or in the spring or just
leave them?

I understand they are normally left to the spring, but if possible I
would like to see them flower next year.
Thanks, Mick.
