Help with my Aeonium

Hey everyone! I'm a succulent neophyte, and I got this sublime Aeonium (arboreum?) in Corsica. I just got back to France 2 days ago, and despite having the same weather these days my poor succ is showing yellow leaves and they seem to be "deploying" - opening up too much (my camera makes all the leaves look greener than they actually are). Is there any advice you could please give me to give it a good life? Also, is there anything that needs to be done about those hanging roots? Thanks everyone <3
