If you are willing to water, they can be moved anytime. But they would be hard to kill. Not sure why you want to move them in the heat (zone 8b) of summer.

great. I normally would never ask but with the rain lately we have had 2 weeks of pure rain and it looks like another 2 weeks of storms. We barely got over 90s here this past week and its july! its been the lowest summer temps i have seen in a while so I figured I might as well do it now and let them rain help me, plus its easier now that the scapes are up I can judge which ones to move and which to leave.
