That's what I use too, Daisy. I think this time I might add in some coco fiber chunks, as I happen to have a nice bag of it that someone gave me.
Patty, I need to re-pot my Phaius this spring after they've finished blooming, so if I can get some divisions off them I'll be glad to share with you. They are gorgeous, and would do really well in your garden. You have the perfect conditions for them. They only bloom once a year, but the blooms last for a month or more, if the weather isn't too hot.
