pruning - wait until spring .... plants are outside ... plants will recover faster and will have all summer to recover
adenium take forever to respond to changes and especially pruning ... but will respond faster if given warmer daytime temperatures, natural sunlight, watering once every 5 - 7 days & fertilization
before moving outdoors - ensure nighttime lows are a sustained 50° or higher ...temperatures lower than 50° may damage the plant - freezing will kill the plant
flower buds form in clusters at the ends of stems - each Flower lasts about 10 days ...each will fall off on its own ... the flowering cycle is a little over 1 month ...then sporadically the rest of the year
your cuttings should callous over before sticking in sand ...... find a straight stick, pencil or length of bamboo ..."punch a hole" in the sand .... then stick cutting in hole ....water thoroughly
