Let us see how everyone manages to protect their sempervivum from overly harsh weather conditions, like intense sun, excessive rain, or drying wind during hot or cold weather.
We were having temps in the high 90's into triple digits. Most of these semps were established enough to handle it, with some evening watering. But I did have some new offsets planted in the bed that just wouldn't have made it without some protection.
We use PVC pipe as a frame with shade cloth over the frame. That did the trick for the 'not yet established' semps. You could use old sheets also. What I liked about the shade cloth is that when I set the rainbird sprinkler going, the water would mist through the shade cloth. This frame covers two beds.
