No blooms on my phal

mary_0524December 5, 2010

I have an orchid that had 3 leaves when I bought it, about 5 years ago. It was in bloom when I bought it and has bloomed several times since. It has not bloomed now for a couple of years. The plant always would start growing a new leaf, then the oldest one would shrivel and die. About a year ago, one died with out growing a new one, so I've been down to two. Now, I have two leaves, with a new one coming, but still no flower stem. I've repotted it and the roots look healthy. Why is it not getting flowers anymore? I have the pot in a south window with a large overhang here in Minnesota, and it does not get direct sunlight in the summer, but does in the winter. My other phals are blooming in the same spot.

Sounds like its just taking a rest. I do know that cool nights, around 55F for a couple weeks is how the pros' get them to bloom out of season, so if you can, you might try that. Just an afterthought, when they 'were' blooming, did you remove the old flower spike, or did you cut it back and allow it to bloom again on the same spike? Sometimes when you do that, it takes a lot out of the plant, and it needs some time to recoup. Hope this helps.

Did it bloom in winter before? Could be a spring/summer bloomer? If it hasn't bloomed for a few years, something is off and the plant isn't happy. Try increasing the light. Some Phals want more light. I wouldn't fertilize with anything unless you want more green growth.

Phals sometimes go into a kind of slump for no particular reason. Shock therapy may work; dump a little light ice from the freezer on it. Not enough to freeze it but just enough to wake it up a bit...

Looking at your post again, the most plausible explanation for your problem is your geographical location. Minnesota is is not the best place in the world to be growing tropicl orchids. The main problem will be not be low temps or humidity, which I assume you take care of, but the lack of winter light. In January your plants will be receiving less than 20% of what they could expect in their tropical homeland. My advice therefore to anyone growing tropical orchids in northerly latitudes is: during the winter months REMOVE ALL SHADING. Let the plants sit in full sun from dawn till dusk until the sun reaches 45 deg at noon ( half way bewteen the horizon and zenith) then VERY GRADUALLY start to shade again. Good luck. PS If this doesn't work try the ice IN SUMMER.
