Last winter I put my phal on a slab of cork. Bought a piece at a pet store (cheaper than a garden center). Used sphagnum all around it, and secured it as best I could with pantyhose. Ok, crude, but the zipties didn't work. LOL Any-hoo...someone that is an orchid person looked at it this summer when I had it hanging in a tree and said "Looks pretty bad, it will probably die. I'd remove the crappy leaf off the bottom tho." Ok, I did that and I could see nice, healthy green roots in amonst the moss. Well, shut my mouth...a couple days ago in the g'house I see it is making a bloom spike!!!!! Yay! No photo of that, but here it is shortly after I secured it to the cork.
Does it have any new leaves since you took the picture above, Anna? That reddish cast to the leaves looks like a bit of a problem, maybe too bright light? The leaves aren't shriveled though, so that's a good sign.
Did you fertilize it regularly through the summer? Phals do like to dry out between waterings, but when they're mounted they dry out a lot faster than if they are in a pot because of all the good air flow around them. Probably through summer it would need watering every day or two if you didn't get rain.
Sometimes plants will put on a flower spike as an adios (as Laurel so perfectly said it) right before they die. Did you leave it outside after the nights were cooling off, and now it's warmer in the greenhouse? It might think it's had winter and now it's spring. My phals all bloom in the spring (but they stay outside year 'round).
A new picture of how it looks right now would be enlightening
Ok, now, let's see if my computer will cooperate on this.
I just went and took these 2 pix. Hope you can see the bloom spike. I think it looks quite healthy. The whole plant, I mean. I had it hanging in a tree all summer and just took it in the g'house a couple weeks ago. I really don't care WHEN it blooms, if it has a desire to it may bloom any darn time it pleases. LOL
You're right of course, since you have a greenhouse your phals can bloom any ol' time. If you give them a week or two of cool-ish nights outside before you bring them into the greenhouse each fall, I'll bet they'll put out spikes every year at this time. Mine respond to the temperature changes that way, too. Last winter, in January we had a couple of nights going down into the 30's so I brought all my phals indoors just for those two nights. By the next week all 4 of them had spikes starting.
One other thing to watch is that water doesn't pool and sit in the cup of the leaves. Phals grow on tree trunks with the leaves facing downwards in nature, so they drain perfectly.You've got it sitting at an angle right now so it looks like the crown would drain just fine, but some people insist on setting their plants "at attention". If water sits in the crown the plant will rot.
I was told that at the onset that it would probably do ok on the cork as long as it was at an angle.
Makes me want to go grab a couple at WM when they have them. I still kick myself for not getting one of those gorgeous green ones when they had them. Now that I know that I can do "this" with a phal, I'm not so scared. And i LOVE the Vanda's. Just wish I could find a couple in some bright, pretty color. My blue one bloomed twice in about 6 months. The pink one is pouting its way to death. Treated it the same as the blue, which is going great. I need to come to Florida and get a couple, I guess. Hmmm...would any of you nice Florida people consider being purchase agents for some Wisconsin cheese as your fee??? I would pay, of course. :>)
Anna, Phals absolutely hate change. When you mounted it on the cork, it rebelled and went into a funk. It looks like it is over that and I think it will do fine for you now. Don't move it around unless you have to.
The bloom spike on the phal is looking great. AND...*drum roll*...it has ANOTHER bloom spike started out of the bottom of the plant. It's maybe about 3 inches long. I feel so lucky!!!!! And on Christmas Day I see this gift. :>)
I've been rescuing Phals off the death rack at Lowe's for $3 to $5 all this fall. They got a little chillin in October when Sandy went by, and now all but one of the rescues has spikes, and one actually opened a flower a couple of days ago! It pays to have patience with Phals, I figure.
Both of these are rescues, the second one has been blooming for nearly 6 weeks!
