Echeveria got the neem oil treatment, too. It recovered better.
I separated out all the younger plants. This central one with the flowering stalk (I think of it as the 'mother plant') is the only one I saved indoors as safekeeping, in case the others don't make it overwintering outside.
Here it is regrown after I potted it up again alone, with its naked stalk buried again:
The young ones outside in the mailbox spot now. They've been there over two months, and are still doing fine! (Also in this picture: pink coleus, sunpatiens, dianthus and flowering purslane).
Others that I had put there in spring did a second and third round of flowering.
