water bout every 7-10 days w ith tap water, let it drain wellbefore putting back into container, needs lots of light and i never cut the stem after flowering, i only cut it back if the stem turns brown, then i cut it to where its still fresh,then when i get a new dide shoots i cut it back to there
i have got phals still flowering at home ive had for years, and i havent repotted them either.
