Verdun, I divide my heleniums in the spring when the clump is getting big. Last spring I put them in two other places as well. Sometimes there isn't room for anything else, so when perennials get big I just cut out the middles and dig some compost and rotted manure into the middle of the plant which feeds them and prevents congestion. Sometimes I dig out the whole plant and replant the best bits. But only every 3 or 4 years. I know you often move plants, I couldn't cope with my garden if I did everything as thoroughly as you do!
