    We cannot grow these very well is South Florida so sometimes when orchid judges see a baby at a local show they are very impressed - until they do the research!

      Guess it's too hot there. You probably have some problems with the Cymbidiums too.

    Easy outside grower here in Southern Calif. I have many blooming size and some seedlings. They are the hardiest plants I own. Reliable bloomer. Protect from frost is only caution which rarely occurs here. Grow in large bark(~1inch) with charcol. 20-20 every 2-3 weeks. Maybe some high bloom late Winter -early Spring. These plants can get huge.

      I noted several of my D. speciosum have what looks like flower spike buds. I just sprayed a few weeks ago with high bloom fertilizer.
