Hi Patgodden, and welcome to NGA and the Sempervivum forum.
Here in the Willamette Valley of Oregon we have had some very unusual weather, and we are starting into what is our drought season and higher temps. Then again, maybe we already had our August weather?
I agree with Julia, this can be a more difficult time to get them going.
What you might try is water the area you will be planting them into, and water the plants thoroughly. The next day in the cool of the morning/or evening do the transplanting. Water them in. Provide some kind of shade if the temps get high, or if they are in direct sun. Or you can wait until spring like Julia suggested.
The rosettes that are going to bloom can be left in place until the bloom finishes and the rosette dies.
Nice photo.
