I think this entirely depends on what hybrid/species it is. My equestris and Ambotris, always spike during spring and flower in the summer. My Little Sister flowers during summer as well, and might flower during winter if it feels up to it. My schilleriana, stuartiana, Wiganiae, and philippinense (and my mini phal which has schilleriana in its background) all usually spike around now. My Tzu Chiang Orange has never stopped flowering. My Queen Beer 'Tiny Doll' starts a new spike, as soon as it's done flowering on the previous one, and same does my Princess Kaiulani. My other NoID is almost also constantly in flower.

So, as I said. It all depends on the particulars of the species/hybrids and their genes, I think.


P.s. It might sound like I'm a wizard at getting my Phals to flower; I'm not. I've just given away most of the reluctant bloomers. :evil:

North side of the house? I think that's your problem right there. Not enough light. Phals like more sun then people like to admit. Put them in a east or west window they will do better.

Mine are in a south facing window and get a bit of direct light most of the sun is filtered by large tree. they bloom like clock work.

mature ready to bloom phals will spike if given approx. 2-3 weeks of 55- 60 degrees with a diurnal spread of 20 degrees during the day

night time 55-60
day 75-80

the temp drop is the signal and how mass grown greenhouses have phals all year round

after the recent cold Ive had the past few weeks I have quite a few spikes going. :biggrin:

I am a Wizard!!! and there is no big secret to getting phals to bloom. Its not inner sanctum illuminati material.

My sunroom gets most of the light that we get in the house. I don't have enough window space on the south side of the house for more than a couple three plants and we have big trees shading part of the south. I have added lights to shine on my orchids in the sun room. I also bring the temp down to 58-60 at night and back up to 70 during the day. 75-80 is much to warm for our physical comfort not to mention energy cost. If all the above won't work in the long run I may end up being a paph fancier only 😀

I have all my orchids in a north facing sliding door window in racks. I have a lot of phals, they get the side with the shear curtain. They do well and have big buds getting ready to rebloom shortly. I do get a temperature change at night of about 10 degrees. North windows can work for phals.

I bought 6 Phals at Lowe's this summer in various states of dehydration and neglect. I repotted all of them immediately, cutting off all dead/dying roots, trimmed sunburnt leaves, and removed spent spikes.

They spent the rest of the summer outside in the heat and humidity, under a tree, with a good watering 2-3 times a week.

By October, when they were brought in for the winter, temps at night were in the 40's. A couple were already showing signs of spikes. Now, in December, 5 out of the 6 have spikes. Some have just spiked within the past couple of weeks.

You may see something yet. Winter hasn't even started, technically :) Fingers crossed for you.
