From my perspective - I mainly grow cacti, aloes, and agaves - the big realization was that in my climate I cannot treat Adeniums like just another cactus - ie. water very sparsely or not at all even in the hot summer months - the plants will survive that way but not really thrive. Since I winter my Adeniums outside, I do stop watering completely once night time Ts drop below 50F, but I have increased my watering and feeding (at quarter to half strength) frequency in the other times of year. So far with good results. A couple of plants that had never flowered, did so this spring and all look a little more vigorous, also more flowers on the plants that flowered, but only sparsely in the past. I use a combination of Dyna Bloom and Dyna Grow (sorry do not have the ratios handy).
