Adeniums have only 2 seasons > wet - and - dry
wet = the active growing season (summer months in the northern hemisphere) water adeniums like a tropical & to saturation
dry = the dormant season (winter months in the northern hemisphere) treat adeniums like a cacti
50°F is a "safe" stay outdoor temperature ...a few hours between 45° & 50° wont do much harm - Assuming the plant has not been watered and potting media is dry
- Watering -
keep track of local temperatures ~
70's water once every 10 days or so
80's water once every 7 days or so
90's water once every 5 days or so
100's water once every 3 days or so
count *any* rainfall as a watering day
make certain water drains out almost as fast as putting it on
cut back watering if night temps dip into 50's / 40's
Never allow adenium to sit in a full of water pot saucer
it is better to not water .... than over-water
rather than getting glazed ceramic pot - find a non-glazed Terra-cotta pot for it .... moisture will evaporate through the sides of the pot ...
allow some extra room in new pot .... fresh potting media and a repot almost guarantees the plant will take off
