    Question how hot can phals get?

    Thanks to all who answered my question. I have one more: Are phals sensitive to heat? My phal was doing fine last fall and winter when it was cold. It was between 60 and 70 degrees inside. (A little lower on real cold days). Then in spring it warmed up fast and bloomed for 2 months. The leaves one by one turned yellow and mushy and dropped off followed by the flower spike when it turned very warm. It got to 108 last week so it was 80 degrees (and a little higher) inside. Are phals that sensitive to heat? I watered a little more often than once a week then. Problem is, I can't ($$$) run the AC more than I do. Thanks again.

    PD

    Phal's are a mixed lot when it comes to heat. I have some that can do 90 and not wilt....others get above 85 and they "faint". The hotter it gets and the more you water, the more you need a fan blowing to keep air-movement going like really well. I keep my ceiling fan on medium and the front windows open for fresh air for the window sitters. My phals are always dried out by mid afternoon which keeps crown rot away. And don't overdo the a/c, it dries your air out and phals like 50% humidity. Alot of people try to compensate by keeping the roots wetter but that only causes rot.
    Good Luck, hope this helps. There are other problems that will cause a plant to turn yellow and die...but the most popular is overwatering with insufficient air movement. I hope those with greenhouses chime in as well because rules for greenhouses usually differ from my windowsill approach.

    Novice, I've wondered the same thing. When my phals went back outside this spring they did very well until the heat really hit. They seemed stressed but I decided to see if they would tough it out. It now gets in the mid nineties on the deck where they are but they seem to have acclimated very well. Lots of new growth and some new leaves. FWIW, it gets in the upper 70s at night so a good temp change. At first when they were stressed I think I didn't water enough, but now I water every two or three days after checking for moisture. (all are in bark). Good luck with yours; I don't think 80 will stress them. Check your roots, too. Connie had some very good advice!

    The few Phals I have love the heat. It is important to keep good air movement. It rarely gets above 95 here. but as soon as it warms up some of my Phal species start growing and stop with cool weather.

    mine grow extremely fast when the temperature rises above 90F and they take 100F with no problem, but they are in very small pots with spagh and they are watered every day in the summer. They would certainly rot if it weren't super hot.

    I put my phals on the top shelf of my grow rack. They are getting huge with new growth and big leaves. It is about 82 - 85 up there. I still water them once a week. Now....if they will only spike and bloom in the spring. BTW I have AC on 24/7. Your temps sound like mine in the Southern CA desert.
    Where are you located?

    Katie, I live in Sacramento, CA We have two seasons: 6 months of rain, 6 months of heat (except for a few weeks of glorious fall and spring.) I'm encouraged that it's possible to grow orchids so far from the rain forrest.

    Sounds like us, except that our winters are beautiful and very little rain.

    The heat does not seem to bother mine , the species love it . It is the increased watering that will get you in trouble if they are not potted in a fast draining, drying mix . Gin
