At this time of year, with rapid changes in the weather--sun and overcast, wet and dry, cold and warm--orchids which are generally pretty regular in their water usage can be quite unpredictable. Two weeks ago, one of my Phals stayed damp three days longer than usual, so I held off watering it. This week, three blossoms on another Phal wilted, early, in rapid succession. Alarmed, I checked it for water and found it completely dry. For the three years I have had it, this Phal (which has no drainage) has never needed water in less than seven days and usually goes 9 to 10 days between waterings. Needless to say, I have learned a lesson. Watering stopped the blossom wilt, and from now, on, I'll be depending far more on checking, than on watering "schedule." It may also be that Phals in bloom use water faster than usual; it seems intuitive, but I don't know that it is so. Anyone? Sweetcicely

philohela is most likely correct, but since you said it had no drainage wholes i'd be worried about root rot, especially if its planted in sphag moss. If i were you, id pull it up out of the pot and inspect the roots, and possibly repot while your at it with a quality orchid medium such as large bark. Make sure the roots are firm and either a "dusty" white (what they look like when theyre dry) or green when theyre wet. If there are any brown or mushy roots remove them ... If the roots look good, than your plant is definately promising. Once you get it repotted, and keep care consistant it will most likely branch from the existing spike or shoot up a new spike from the base of the plant in a few weeks. Orchid care can be tricky, but once you get a hang on basic care, it is a very enjoyable (and addictive) hobby. Good luck, and happy orchid growing! - Franco

Sheila, I would say yes it was the hot wind from how quick it blasted. I've blasted my share and it takes a couple of days usually but mine are all inside. I have 3 equestris, 1 is mounted and all are under flo lights inside and not near windows. I water the mounted every day but skip a day every now and then. He's very different from yours as the leaf span is 3" tip to tip and regularly keeps 3 of them (center of pix below) !!! Bloomed every year for the last 3, first 1, then 2, this year 3 blooms !! Not much of a sequential bloomer, the mounted one ! His tiny (3 years, 4.5" pot) mother plant puts out at least 3 spikes and is short term sequential with them. She's a keiki freak and just started another. My equestris 'Riverbend' just did a year long sequential bloom, took a month off while putting up a new spike and is right now busy sequentialling (?) again !! I think you did right bringing yours inside but you changed the environment again after only a short time. Pick one and let it settle down and adjust to it and you should be alright, but not necessarily with this spike. upper left background = P. bastianii, left lower = Den. Peng Seng, left mounted = Dinema polybulbon, upper background = P. equestris 'Hana Nguyen' AM/AOS (mother plant), foreground mounted = P. equestris 'H.N.'
