Take as much root and soil as you can, protect the rootball while moving (tarp, pot, bag, burlap), and plant ASAP into a prepared hole which has been pre filled with water, do the move early in the morning or late evening if possible, or even more ideally while raining or overcast, if you can shelter them from direct sun, that might help. Keep the rootball as intact as possible and get help if possible for lifts and moves.

They are pretty tough, IME, so they should be ok if you follow those excellent directions.

Also, make sure the plants/rootballs are thoroughly watered the day before you make the move. Will help to keep rootballs intact and prevent against any root desiccation.

should be a great time to do it in z5 ... the nights are cooling.. which means whatever the day throws at it.. it can recover at night ... imo ... timing is about perfect ...

so just go for it ...

it you planted them.. and you recall the root ball planted.. just go a couple inches bigger ... if you can lift that size ..

if you can.. sharpen your shovel ... its surprising how much easier it all is when your not using a rusted dull shovel ....

all you need to add to the primer below.. is digging it out ... dig the new hole first .. approx size ....

and if you lose or it aborts the flowers.. dont be surprised .... you do what you have to do... losing the foo foo flowers.. is not an indication of anything wrong with the rest of the process ... and would be basically normal ....

It is never ideal to have to move something in bloom but the instructions above are good the one about having the new hole ready is very good make sure that hole has been watered too .
