I have a rose at the end of pergola post, it has not been brilliant (probably my clay soil) but last year did get plenty of flowers, I am going to have to move it to add another stitch of panel and another post . When should I move it , do I move into a pot and leave there until later, move only when work will commence (what if I disturb growth) , just move it over a little so not to be in the way of panel (or OH just standing on it) . Reading conflicting views on web /books so confused now.
