Can I divide these now?

Daylilies, sedums and irises (flowering right now)?

You can certainly divide Daylilies and Sedums right now but Irises that are divided in the spring usually don't bloom that year. I have heard 6 weeks after blooming they are okay to be divided.

Generally, it is not a common practice to divide anything that is still flowering. Some plants can be divided soon after flowering. Waiting six weeks for your irises seems to be good advice to me.

I divide my irises the end of June or beginning of July, after flowering. This gives them enough time to set a healthy rootsystem by fall. Sedums I divide in the spring. Marg
