My irises seem to be done blooming.  I need to thin them.  Is now the time?  Or should I wait until fall?  I also have some gladiolas planted close to them that are coming up.  I don' want to disturb thoseCan I just cut the irises down now and dig and thin them in the fall when I am digging the gladiolas?  
Has anyone ever had luck leaving the gladiola bulbs under ground all winter?  I usually dig mine, then store in sand in theasement for winter, then replant in spring.  Now that I think about it, I wonder if that's even necessary anymore given the warmer winters we have now.
Advice?
Thanks!
