So i am moving my VFT outside and hardening it off. it seemed to be doing okay indoors for a few months but then the leaves started turning black and mushy and dying. i am trying to save it. there are still quite a few green leaves and stems on it. Ive only had it about 5 months and it is in the small plastic pot that it came in with that same potting soil. i water it with only distilled water keeping the soil moist. i read that they need high humidity levels and that they normally live in bogs so its pot should be submerged several cm in distilled water at all times mimicking it’s natural habitat. I’m not sure where i read this but i have been doing this. Now im worried that i have drowned my plant. should i repot it in perlite and sphagnum moss and move it outdoors?

Pothos (common name today) is kind of a weed in the tropics and can be in the house if you let it do its thing. When I bring mine indoors for winter, I find long vines have rooted in the ground and they break away from the mother plant when I lift the pot. Typically I just let those stranded vines behind for Jack Frost. The mother plant will soon replace all the long vines that are cut off or broken. You could chop it all the way to the ground and it will come back but that is drastic. I chopped this way back since 2014 when I tried to save all the vines. Last year PS: this is what Pothos looked like in Maui last year

Mine is shorter, with long fronds. It isn't easy: I held onto one, twisted it around as though wringing out something wet, again and again. Too cheap to hire someone. [Now it's too tall though.] Check this, just for info: Dead brown leaves / the skirt hanging from a palm tree doesn’t hurt the tree; in fact, they help shade the trunk from strong sunshine, and will provide bird-nesting sites, but they can be a fire hazard and sometimes harbor yellowjackets. If you trim a palm’s skirt, don’t do it in the summer; the fierce summer sun will scorch the previously shaded trunk.

looks severely sunburned ... i would tip it out of the pot.. and look at the roots ... if rotted.. be done with it ... if active with new growth ... i would put it back in the pot.. and water properly for a month or 3.. and see if new leaves appear ... any leaf with green can still process light into energy ... and i would only cut one off for each new one that emerges .. if in 2 or 3 months.. its settled down.. destressed.. i would repot it as suggested above ... i dont like to heap stress upon stress .. lets deal with one at a time ... if you want to go thru all that.. or any derivation therein ... just to see if you can save it.. go for it.. but if its going to piss you off every time you look at it.. just be done with it.. and move on to a new plant .... ken
