how to bloom my phalenopsis

[adinner]

I have several plants and the leaves look good but they never bloom.

What are its growing conditions like?

Phals only bloom once a year, to help it you could drop the temps down a little. That should help the plant to send up a spike.

Like Hannah said, a temperature drop helps phals produce spikes.

They can flower more than once per year, but then they need to be really happy, I think. My mother's house is apparently this phalaenopsis paradise and all her plants are doing everything at the same time, all year round. I'm just amazed how her cheap supermarket NOID phals produce roots, leaves and spikes almost continuously throughout the year. But that's exceptional and I got no idea what the secret ingredient is.

I'm babbling...sorry.

In addition to temperature drop, I personally like to cut off old spikes when they are done blossoming, even if the tips are still green and alive. That gives the plant a bit of a break to focus on roots and leaves only for a while and I get a nice, new spike (or spikes) instead of a so-so flowering on a long and lanky old spike. But that's just personal preference.

How much light do they get?

I don't know....I've had several Phal's that took an almost 3 year nap. I rescued them not in bloom and it took 2 1/2 years to bloom. (they now bloom twice a year) My Grandma's Phal (which I've inherited) Took a 4 year nap after a year of blooming. That Phal has only not had a spike or bloom on it in the last 5 years maybe 4 months total?? Crazieness!!
I have a theory that Phal's like to be snug in their pot, personally. Not roots rotting because they can't breathe....I have no scientific evidence to support it.... but the ones that have taken longest to re-bloom got to the point where their roots pretty well fit the pot. I thinks it's a conspiracy theory as to what makes the darn things re-bloom...I don't think anyone really knows!!! <----joke...but maybe not...

How snuggy the roots are in the pot has nothing to do with flowering potential, just so you know.

A few things to be met in order for phals to flower every year like they should.

Enough light : This would be the single most neglected factor not just for phals but other genera as well. Many times ambiguous and misleading line saying "low light" "shade" lead many people to think real dark shady spot in the house. They actually need very bright light to grow and flower well. just not in the cooking sun. If you ever visit nurseries where phals are growing, you will be shocked to see how bright it is.

Overall condition of the plant: Properly grown and healthy.

Then seasonal temperature change. but this is not that important unless you heat up the house very warm all the time.
I grow all mine indoor where it's pretty warm all year around and they all bloom on time and all. they are sensitive and detect just slightl temperature fluctuations I think.
