Suckers on tree peonies - help needed

Posted by mxk3 z5b/6 MI (My Page) on

I noticed two of my tree peonies are suckering - I must not have planted them deep enough to prevent the rootstock from sprouting.

How should I go about removing the suckers without damaging the graft/tree peony? Should I try to dig down with a spade? Should I dig the whole thing up, cut off, and replant as deep as I can? Help!

RE: Suckers on tree peonies - help needed

I'm not sure what the right answer is but I'll tell you what I did.... :-) One of my tree peonies threw out suckers in its first year or two. I was curious to see what would happen so I left them alone - I wasn't all that keen on the tree peony (its leaves get ugly with fungus by late summer....) so I didn't particularly care if it died! The suckers produced beautiful pale pink single flowers. I love single peonies so I was really hoping that the 'tree' part would die and leave me with the single herbaceous peony of the rootstock! After a couple of years the single peony disappeared and only the 'tree' portion is still there. When I did some checking, I found something that said the rootstock suckers usually ony appear in the first couple of years. So I don't think you need to do a lot of deep digging - just cut them down if they worry you.
