Hi, desertrose, I'm from Vero, east coast 50 miles north of Palm Beach. I have two Robert's delights, Pachara Red and #31, a vanda species, a Asoc. Vermillion and a brand new Robert's delight Blue Wax. I'm sorry, I have been trying to upload a picture of my "garden" for you, but, for some reason, it continues to fail.
I spray with Worm Tea about once a week. I will water with a sprinkler several times a week when I water my other plants and vegetables that are around it. I have them on Shepard's hooks in dappled sun starting this time of year, early spring, and full sun in the winter, about October through January. I haven't fertilized with anything other than worm tea.
When I first got them, I was dousing them in a bucket almost every day. During the summer last year, I put them out under a tree and the humidity took care of them completely. They were way too far away for the sprinkler. I found they were extremely happy. I have cared for them like that since. No more bucket dousing, only worm tea and the sprinkler.
My Robert's Delights have been flowering ever since. The blooms last one to two months, sometimes, like right now, there will be two stalks. I always have large, multiple blooms. In fact, right now, my avatar is a picture of one of my Robert's Delights with the recent bloom. They have been on since the beginning of February.
I have no special secrets, just happy vandas. I have them in open baskets, no sphag, just roots that are about one inch around and as crazy looking as curly hair that hasn't been combed. When I got them they all had the long straight strands of roots. Since I don't water them like the nurseries, from the top down, they spiral in their own way toward the humidity they love.
I hope this has helped you. My vandas are my favorite plant since they require next to no extra attention. Good luck!
