Conflicting info about pruning Olearia x Haastii
Don't ask me WHY I put one of these in my raised bed ... I didn't know what it was (mainly used for hedging and no idea how big it would get - no info on label). It seems really happy but I've got two conflicting pieces of advice as to whether I need to trim it now that the flowers have spent - all those flowers are now a deep brown.
This is the advice from the RHS - definitely saying to leave it until the Spring.
But this is what it says about the same plant on a site that sells it ....
"Care advice for Olearia x Haastii - Daisy Bush needs a good trim after flowering and will benefit from mulching. It may also need a tidy up in early spring."
Is it me or is that saying two different things?
The thing is, I don't know WHERE on the plant to cut (when I figure out when to do it) - is this what is known as a 'woody' plant? I wish someone would draw some pictures (for idiots like me) that shows HOW to prune - with arrows pointing to the cut points.
So do it now because it's finished flowering (the flowers are completely brown)? Or leave it until next Spring?
