Welcome to the Adeniums forum
adenium leaves turning yellow and falling off .. is perfectly normal
but when several leaves yellow at the same time, it signifies the plant is under-watered (for adenium, under-watered is far better than over-watered)
- 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
Do not water - if night lows are predicted to dip into 50's / 40's
water in several passes to completely saturate potting media from top to bottom
be certain water drains freely from & away from pot
never - ever let plant sit in water ....
do a restart .... if night lows are a sustained 50's all night ....gradually move plant outside .... .... leave plant outdoors 24/7
try for at least 6 hours full sun - follow temperature / watering above
for example - my plants start the day with filtered sun to about 11am ...then full sun to sunset ....if it is 90°, I need to water in about 5 days ...if it rains before then, I tack on a few more days
adenium respond to changes very slowly - so do not expect anything to happen anytime soon ...
