GardenNub, i'm so sorry, i just looked at this post as it appears in the 'View unread posts" section, i'm really sorry for not seeing this, you should have send me a PM or a message via our profile section.
I am as well not so good with pinguiculas, the pinguicula that you send to me, it looks like yours, and it looks like is dying, but the other 4 pinguiculas moctezumaes are doing excellent, somehow i have not manage to get pinguicula plimuliflora grow well, but i still have hopes that it will come back from the death, and it will grow as the best P. plimuliflora ever.
I have found out that P. Plimuliflora likes really wet conditions, and have been said to be found living even under water, which i found shocking by this post, and what happened with my plimuliflora, they require extremely high humidity during the growing season, and temps should be around 80F, but likes or appreciates as well full sun.
I think our problem was humidity, and sitting water for your plant, and growing it in the tray method indoors, justh a thought.
How i'm keeping mines right now:
below the silica, i put LFSM somewhere in the middle to the top part with silica, mix with little peat, and the silica on top, but at the same time, LFSM sorrounding the plimuliflora giving the right amount of humidity. Light i'm giving them filter sun 2-3 hours, and as well as natural daylight all day.
It has not grown or move, but my hopes are still strong, and for sure i will have the plimuliflora as a healthy plant. I also change the media a bit and added more peat, and remove the silica a bit( i did not bother the moctezumaes, i took all the media but not where the moctezumaes are growing).
Moctezumaes are gorwing really well for me, and they look like they don't like sitting media, which i see completely different in your media, yours looks like more peat, and very little silica, i can as well see the pot is small maybe a 4inch?
, in my opinion that's a no for keeping plants indoors, not outdoors because the media indoors keeps the water because there's not sunlight to evaporate the water fast, and i see you use a tray method, which doesn't looks like a good thing to do for a plant that is growing indoors, perhaps the tray method for small pots with plants that are growing outdoors is fine, and then leaving small pots outside without tray method can lead to the death of the plant because the water evaporates faster, and if there's no circulating air, then is worse.
but don't give up, i'm getting a P. Florian maybe tomorrow, and i hope to have a good experience with it, if i don't, i will try once more, and once more until i get tired of trying!
Good luck, and next time let me know fast my friend
