I purchased a potted Cora Louise and planted it with the pot and ground soil line level. However, now I'm seeing pink buds poking up - do I need to add more dirt? (I'm in CT zone 6.) Or are these extraneous and let them freeze?
The other complicating factor is that the plant has peony leaf blotch, so I want to remove as much above ground matter as possible so it has fewer places to overwinter.
