Same way you'd move them any other time of year - but I wouldn't advise it. You haven't said how long they've been in, and most roses put down very deep roots which are impossible to extract intact at any time of year - midsummer is possibly the worst time to move any plant at all.

If you absolutely have to, prune them heavily just before digging them up--the object is to remove 1/3-1/2 of the foliage--get as large a rootball as you can manage, keep the rootball together as you transport it, water deeply right after replanting, use a strong root stimulator, and water frequently for the rest of the summer. If the soil falls off the root ball, go ahead and remove all the leaves--it can recover better from defoliation than it can from dessication.

Thanks,
I'm moving home and don't want to leave my babes behind. I,ll wait as long as I can.
Your excellent advice will be followed to the letter.
Thank you so much.

Be sure that the new owner knows that those bushes aren't part of the sale!

I wondered if there was a reason you needed to move them now - but Tugbrethil's right, if you're selling, they're part of the deal unless specifically excluded. If you're renting, fine...

I hadn't thought of that! Don't think new people are gardeners, I'd bet in a year the whole place will be bricked over.

Thanks for the advice will sort it.

If they'd been in pots already, you can take those away, but anything planted is considered part of the property.
