Slightly scruffy specimen, longest leaves maybe 75cm long, in my newly acquired garden. It was obviously planted central to a narrow (1m wide?) bed, but it's spreading and drooping forwards over the adjoining path leaving a good third of a metre gap between it and the boundary fence behind it.
What I want to do is to ease/force the whole caboodle back. I will dig a hole behind it, loosen and of course inevitable cut some of the roots at the front and push the whole thing back, bed it in and perhaps stake it to stay put. I want it to grow more upright, not slump forwards!
But when? 'Spring'? late March, say?
Your thoughts please.
