Keiki or Floral Branch? Female
Default Keiki or Floral Branch?

Hello all,

I'm not new to growing orchids (mainly Phals) but am new to trying to propagate them.

I have a Phal orchid that I successfully pollinated about 7 months ago and just harvested four pods about a month ago. The spike didn't die back so I left it. About a week ago I noticed a change to the second lowest node on the spike. It looked like it was starting to swell so I've been keeping an eye on it. Sure enough something is happening.

I have attached a closeup of the node that I'm assuming has differentiated. Is there anyway to tell at this stage whether it might be a Keiki or whether it's going to be a floral branch or will I have to wait a few more weeks? Nothing has been applied to this node.

If it helps any this Phal seems to be in vegetative growth stage at the moment. There's a new leaf coming out of the top of the leaf stalk. I'm not sure if this might dictate what this node might be. Meaning vegetative growth stage is more likely to produce a Keiki whereas flowering stage is more likely to produce a floral branch.

I haven't been able to find a lot of photos of Keikis at the early stages but maybe that's because there's no way of knowing this early on in development.

Thanks for any help!

Welcome to the Orchid Board!

I think it's too early to tell. However, when I have had secondary spikes on previous spikes, they usually grew during normal spike growing season.

Thanks for the speedy reply. I thought it might be a bit too early to identify but of course my excitement is getting the better of me. :-)

Some of the pics I have seen of an early stage Keiki appear to be a few weeks along in development but they seem to all have spiky tips. Mine appears to be rounded at this stage so if a spiky top is indicative of a Keiki I hope this changes as it grows out. :-)

I will update this post as it continues to grow.

Thanks again!

After doing a bit more reading on Keikis I read that the spike should be place in low light conditions. Bright light will cause the node to produce a floral spike and low light will cause it to form a Keiki (if the node is still undifferentiated). My orchids are currently in an eastern window with bright but indirect light.

I'm not sure if the node in the picture is differentiated or still undifferentiated. I thought differentiated given it has started to swell and grow but some posts I've read (with pictures) seem to suggest this might still be undifferentiated.

If this is the case that it's still undifferentiated should I move it to a spot with lower light?

It might be too late regardless if this has differentiated but if the recommendation is to put it in low light I will do that and watch to see what happens.

Thanks.

I thought I would post an update on the progress of the node on my Phal. This is about 2 weeks since my first post. I still can't tell what it's going to be but the sheath just split on it which indicates the node is still growing. I have also moved this into lower light only because I read posts saying low light is better at producing a Keiki and brighter light for producing a floral branch. I'm not sure if this is true but I want a Keiki so am following the directions of others in hopes of success.

Watching this grow out is like the old saying "A watched pot never boils". It seems to be taking forever. :-)

I will continue to provide updates.
