Thanks, Ursula. We're always learning something on this site, aren't we.
Lovely vanda, Alice and fragrant, too. I agree about winning the lottery first, though. Wow, $60 for a small start of that plant! I'd kill it for sure.
Chris, yes remember these are epiphytes, not terrestrial plants so they don't need or want to have all their roots under ground. Also VERY important when you do re-pot to slant the crowns so water will drain out. See in Anna's picture of her mounted Phal how the leaves are hanging down? That's the way they are designed to grow in nature. Crown rot is almost inevitable if they are planted facing up, like they do in the big box stores.
Mine are all hanging sideways over the edges of their pots, and look like they're crawling out when they stick their roots out every which way. Sometimes they do crawl out, in fact. That's when they get mounted on a piece of cork or tied into a basket.
