Hello everyone. I have a raised bed with a handful of these plants in. Can I cut these hard right back now? the leaves are troubled with a fair bit of rust. I think thats what it is or the leaves have totally dried out? I wasn't sure if should just the each flowering stem back or can I be fairly brutal to tidy it. I read somewhere else not to cut back in autumn only spring?
Many thanks Verdun. Appreciate your help with this. Should I try and keep a lot of the leaves and just snip the flowers to the base or can I literally dig them up, divide and give them a chop to say 4 inches and then replant and water?
Thats great advice - thank Verdun
