Good luck! I'm sure they'll like having more space, and any roots that break will soon grow back. Have they bloomed yet? I'd let them bloom first and divide after summer dormancy starts as Neal suggested. Keep us posted... I'd love to see more photos! Your garden is lovely... Are you next to a park or ballfield? I was trying to figure out the pretty green backdrop to your flowers...
