If they’re older and have bloomed in the Pat, it might be time to split them. Dig the up carefully in Autumn and plant them further apart after splitting the roots, making sure to include a rhizome eye in each root collection. Do not plant the eye deeper than about a half inch. Do not expect blooms the first or second Spring. Watch them carefully in early Spring for buds and pinch off all but the largest o ea on each plant. After that they should do well without any more fussing.
