Hi Paul, I find some of the semps can bear the heat, but a lot can't so the leaves dry out or they bolt. So I have to move them to shade, and hope for the best that they just go somewhat semi dormant till the intense heat passes by. But this week is cool down week woohoo, so they get a reprieve, next week back to the oven. Yes, noid means no identification.
I find the semp arachnoideum ones, the ones which seems to have cobwebs can tolerate our heat, but I do get some shade from the city trees. But as I have said once that blanket heat is here, it is survival of the fittest. I try to water them, directly at rootzone early in the morning before the sun hits the garden, to help these succulents cool down. My Kalinda did well, but unfortunately a nasty pesky found its way and killed it...so sad. That is something you have to watch out for, at times, something at the base of the plant. Fuzzy white annoying thing, so hard to reach since it hides right at the leaf end nearest to the plant's stem. I tried to use diluted alcohol mix, but I guess it was in stress with the heat and being attacked by that thing.
Yes. most of the succulents seem to go in semi-dormant state when temps are in the upper 90's to triple digit range, going into self preservation mode. They just wait till temps return to the amiable 80's. Sometimes you seem them quickly dropping their outer leaves and just keeping the tighter rosettes.
Something I learned here in the Semp forum, using chicken grit as top dressing, my semps and other succulents love it!
