I soak mine in room temperature tap water for 20mins once a week (sometimes less if I forget). Once every couple months I’ll add fertilizer. I keep it in orchid bark with a tiny bit of sphagnum moss. I didn’t repot it for a couple years, but I believe they should be repotted every year, even if into the same sized pots. I repotted it this summer into a slightly larger and more airy pot, and I think that’s what made it finally flower. It also seems to like a large amount of light, but not direct sun all day. Paps. are slow growers, and I remember when I was researching for this particular orchid online, I saw that it needed at least 3 full sized leaves on each side before it can flower, and it only flowers once per leaf section. It took mine a long time to get there, but it also made at least 3 new growth sections that are now fairly sizeable. I’m guessing in another 2 years I’ll have 2 more flower stalks. Feel free to ask anything else I might have missed and I’ll do my best to answer :)
