Yes, agree with Karen. Here in my area, I get the blooms at the peak of our summer when it gets very dry and very hot in the 90F to 100F ++ range. (32C to 37C ++)
In Spring here in my area I usually wait till our outdoor overnight temps is at least 50F and higher (10C ++) before I attempt to bring it out. Adeniums are so cold sensitive, so if I can delay to mid to late Spring to reach those ideal overnight temps, so be it, rather than risk cold damage. So if you are planning later on to move it out monitor your overnight temps.
Position it slowly in part shade outdoors later to acclimate and then after about a week, move to more full sun position. As you continue to see it actively growing leaves, you can start watering daily or as needed just depends how dry your area goes. But if your area is a rainy summer area, then you have to just let Mother Nature do the watering but do monitor and protect if if your forecast is torrential downpours. Too wet media is something it does not like either. Summer time is super dry time here, so I end up watering daily.
Good luck on your plant! Keep us posted how it goes!
