This is from Facebook, and I believe it to be true. Haha, after all these years, I should be practicing this, but am just getting started!
2 months before you want the adenium to bloom,
1- Do not water the Plant for 2-3 weeks.
2-After end of 2-3 week dry period, water only with N-P-K 8-24-24 or orchid fertilizer instead of regular water for 3 days
3-, again stop watering until small flower buds start coming out.
4-Than you can start regular watering (2 to 3 times per week). Never let the water on the flowers, it could break the buds (Only around the Caudex)
In 2-3 weeks you will see many flowers coming
