Nice to see the improvement there Crissy! We get those triple digits here in my area too during summer but it is a dry furnace heat, and I can get away watering my Adenium more frequently with our humidity levels very dismal oftentimes at 0 to 30% only, but I still allow intervals just the same, this plant ably hoards water in its trunk and makes fatso roots/caudex below soil line later on.
I took a photo of my other Adenium before while it was dormant, curious how the roots below soil line looked, and it showed me how it has started to form a nice caudex below. The lghter green part is the one above soil line and the yellow, lighter looking part is the root/caudex part.
