Mtssa. Kauai's Choice 'Trop. Fragrance' new growths and yellowing leaves

Looks like Phoenix, AZ. Now that's some heat. Thinking back, this orchid was packed in sphag when I got it. I'm sure it needs more water now.

When summer hit in late March days in the growing room suddenly went from 80s F / mid 20sC to 105F / 41C and nights were around 85 F / 30C. Three nice Oncidium hybrids in sphagnum in 4" / 10cm pots collapsed and died within days. Maybe if they'd been in bark and drier they would have survived - who knows? But I had trouble watering them enough during the winter, even in the moss, until I stood them in dishes of water.

I have only visited the west briefly and it was in winter, which was pleasant. I have a hard time imagining 105 f. Although, we have seen it. And joke as much as you like, humidity does make a difference, and we are often very humid. As you have aptly pointed out many times, where we live makes a good deal of difference in how we grow the same thing.

105F is late spring/early summer. It gets better and better.

It's in an East window now with temps down to 64f and up to 71f during the day

That is not too hot. I also have a Mtssa and during all summer it's under constant low 80's and 15 to 20% HR.
Do you know your HR and temp in the growing area?

I also think you should water it more. I sugest, after a good soak in the first week, in the second start a new regimen by giving it small portions of water 3 times/week, just enough to keep it lightly moist.
Keep monitoring it, especially the pblubs. They should plump if the watering is correct.

105F is late spring/early summer. It gets better and better.

I like the heat. I wish I could have those temps year round.

Update on this one, it's doing great! To the left and in the center are the new growths, no more leafs were lost. I took the advice on increasing the wateringhere are some happy roots

Yay! Success! Mine is just stalled...

Lots of sun, mine is in an eass window, it did have some CFL lighting to help it through winter. Also, a couple treatments with kelp, and it does like water. I'm excited about this one. Flowers and fragrance were great when I first got it.

Light is right...More water on the way.

Phoenix, Arizona in the summer? Be careful what you wish for!
