When is the best time to move a hydrangea,autumn or deep dark winter?
No way an expert, but I'd move it now as the soil is still warm and gives the plant a chance of getting some new roots established before the winter comes in.
Yes so do I, move now, the ground is warm and wet, do it before the frost starts.
Yes - I'd agree, try and get as good a root ball as possible
Thanks for all your advice
