im pretty good with roses here in the northwest. but I don't know anything about how freshly planted roses will react to your extreme weather over there - especially being this late in spring. "extreme" compared to us here in washignton. we have very mild winters and very mild summers. two days ago it was 50 and raining. perfect conditions for planting! today is bright sunshine and 80 degrees, which would probably be fine for us as well because it cools down quickly as evening approaches and it still gets into the 40s at night. at this stage of the game however, I would put them in pots, yes, and keep them there until next spring. maybe a few hours of cool morning/late evening sun only. even still they may have a tendency to droop a bit in the shade simply from the heat and drying winds. which means their watering schedule will need to be watched closely. I believe they will be ok however and you may even get a flower or two later in the summer if enough growth is put on between now and then, but I wouldn't count on it. but at least they'll get a good start on establishing roots that will sustain them through this coming winter. then next spring you can plant them in the ground if you choose. if they survive winter that is... hope this helps!
