Glad you're enjoying them. We put a line of green Dudleyas in the park in the spring, including a 4-headed one that I induced to branch by coring. The squirrels have been snacking on them and a powdery plant we put in the same time. As long as they make it to when the rain starts, they'll be okay.
About half the plants I was trying to propagate have been attacked by mealy bugs. Kind of a late summer thing but it's ugly this year.
Looking forward to getting some rain and washing those plants clean. For now I am blasting the bugs out with soap water.
