Do not soak the roots or water your plants right after you pot them up. Just give them a few days in their new location, maybe water to 50% completion after a week or so, and maybe start watering in earnest a week after that. The Adeniums may drop all their leaves and go dormant, in which case you want to back off on the water. That is a nice big medusa and you can look forward to fantastically fragrant flowers.
