I only have one Paph I would consider "root challenged". The secret, I believe is to assure you don't lose the remaining (or the only ones it ever had
) roots. To do this, be sure not to overwater. For most of my Paphs, I water every-other-day. For the root-challenged one I water once a week (or I "heft" the pot to check it's heaviness. Heavy means wet.) I really wish I could find clear pots for this job as it would be much easier to determine dryness of mix. Roots will come automatically with new growths (not so much from old growths.)
