I would pot them and plant during early Fall.

Last year I potted mine (after soaking overnight) in containers just big enough to hold them. Some had giant roots and needed a 5 gallon, but a few were smaller and went into 3 gallon containers. I only gave them morning sun for two hours or so, and that was it. Only one died (it looked iffy to start with).

I have ten more roses from brecks coming. Exciting!

To keep the roots from overheating and to keep the roses from drying out, you may want to mound the tops with shredded hardwood mulch, compost or even plain topsoil. When you see good top growth you can gently remove this protection. THEN just make sure they don't get sunburned by introducing them to full sun gradually.

I put all of mine last year in pots. I had 15. I filled some ice chests with water and was able to soak several in each chest. I was really busy so they stayed there for about three days and only got sun about 3 hours every day. Then I planted each one using a good potting mix in large pots. The pots are 20" tall and 22" wide. Most of them survived and grew well. I am preparing beds for those roses and they will go in the ground this fall.

Thank you all. I am going to pot them up in fabric pots when they arrive. In the fall they will either go into the ground or into larger permanent pots.
