Phal. parishii only leaf dying...
 

Hi all! I got a small Phal. parishii mounted and the one leaf it had is slowly yellowing... The roots are happy and green, but if it loses this leaf, is it doomed? I water every two days, as it's mounted on cork and has nice sphagnum keeping those roots happy....

Would love to hear your thoughts! Thanks!

Phal. parishii is a deciduous species! No need to worry!

As Becca said it's deciduous, but from what I've read (I don't have experience with it, just read about it) this is usually in the 'dry season' which naturally would be in the winter months in it's natural habitat (Himalayas).

I think the answer is that the plant isn't doomed because it's used to loosing it's leaves, but it may be that it is being kept too dry and that is the cause.

Here is a link I found about this one.
Phalaenopsis parishii

I have mine in extremely high humidity (70% to 90%) and it is potted in moss so it stays pretty moist and it still loses leaves!

I have a few of these (keep on trying). The same story as yours. However, the one I got from a local grower is fine. One of the ones imported from Malaysia took a year to rebound and is now growing a new root. It may just be that the shock of relocation was too much. I have a philippinense and taenialis that did the same. They are all grown in a terrarium (although not the same one as they require different temps.)

Thank you everyone! I just got this about two weeks ago and if I remember correctly, it only had one leaf to begin with. It's tiny, so it may just be trying to acclimate to my conditions. It's mounted on cork with a fair amount of sphagnum and I have been watering every ore day, so perhaps I should increase that to daily in the morning. The roots look happy and green, just this leaf (which is only as big as an almond) is yellowing and had me worried. As for my humidity, I'm in Utah :( and I should probably increase that. The lighting is from an East window, it gets light, but I could increase that if needed as well.

Thank you my friends! Appreciate your imput and expertise!

I had no idea that these were deciduous! Mine frequently gets down to one leaf, and then I panic until I see a new leaf poking out. Guess I'll be less worried now. :) Surprised that it never went completely naked since my humidity is not the best (mine's mounted), and sometimes I forget to water it...

My Lobbii kept its leaves for 3 years. Then I went on holiday and it l slowly lost all its leaves... like yours it's roots were really good looking.. It ended up losing that last leaf and about 3/4 months later it put out a basal keikie... It has not flowered for about 18 months now but still has tons of roots on it and 3 leaves .. So don't worry too much - just make sure those roots keep on looking good! :crossedfings:
& good luck!
