Yes - as the others have said, the plant is on the verge of dormancy ....
leaves falling off & yellowing is normal -
With-hold water for 3 months - mark the day on a calendar & resist the urge to water -
watering now can kill the plant
Since Colorado is still in the 30's to low 40's .... place your adenium indoors near a south facing window
(east or west facing window okay)
Never let your adenium freeze -
In the meantime ....here is a tried and true adenium potting mix ... but wait until spring to re-pot
Mix together:
2 Part: Coconut Coir -
1 Part: Poultry Grit (chicken grit) /or Pea Gravel
1 Part: Sand - coarse Builder's Sand, or Leveling Sand, or Horticultural Sand
1 Part:: Lump Charcoal - Break-up (crush larger pieces)
1 Part: Lava-rock – (volcanic cinders or pumice) (crush larger pieces)
Optional: mix with above
1 Part: Redwood Bark / Orchid (Phalaenopsis) Mix - Break-up, cut or crush larger stems & bark
1 Part: Perlite - coarse
In a Adenium re-potting mix pinch?
Can substitute regular Soil Mix for Coconut Coir
Can safely substitute a half and half mixture of Orchid / Phalaenopsis Soil Mix (mostly bark and rocks)
mixed with Cactus / Palm Mix
(both available in bags at most Big Box Building Stores)
