Any advice for planting red leaf patio peach trees now?

I bought red leaf patio peach trees in the middle of May to arrive in a week from Groupon. Unfortunately they were delivered only several days ago. Now I am in doubt if to plant them in large pots now or wait till autumn. Any ideas? Thanks in advance.

 

Must admit never heard of red leaved peaches, but I'd say if they are pot grown you can pot on at any time now, allowing for good watering from now until the monsoon season sets in.

I'm sure we are going the get a monsoon at some point, as the weather in the UK always resets the balance at some point.

 

Black Orchid, I would pot them on now.
Make sure the roots are not congested and soak the rootballs for at least 20 minutes before.
Kept watered they will establish grow for the rest of the summer if potted now

 

Thank you all for the replies. I will plant them tomorrow.
