Den kingianum. Bought in bud, should I still give winter rest

[kavanaru]

Camille, if it does not bloom but produces keikis or new growths, the problem is that you eithar give too much water and/or keep too warm... be precarious with water and cool it down to almost freezing! You in The Netherlands, so you should not have a very strong winter (similar to ours in Alsace but with more rain ) keep it outside of a window as long as you don't have temps below 0°C (but protected from rain!) bring it then indoors, but try to keep it at the coolest place in your flat...

Ok thanks Ramón I understand now.

One of these is putting on new growths already AND has flower spikes. However I think most if not all of the flower spikes are coming out of keikis.

The other has no current active growth and has flower spikes out of the older looking canes (not this years growth, which looks slightly different and younger than the rest). Is that normal, to flower from the slightly older growth.

I would say YES at least that's what my only kingianum does

I think Ramon did a good job in explaining things for the most part.

I'll just add that the rest period is not concerned about this current flowering season, it's about the next flowering season.

How long should the rest be?

I still have mine outside on the front porch under roof and only bring it indoors if temps go below 35'F.

Thanks.
Cheers.

Anyone?

Back when I first got my kingianum I read up on this, and I think that winter rest is supposed to end either when it's spiking, or when the new growth starts. I really can't remember. Trying to find the thread that I got this info from!

Maybe here, Camille?

Thanks! That's what I was looking for, but had forgotten that it was an article!

[DelawareJim]

Thanks. I'll just keep my eye on them.

Since my plants are fairly young, and I'm new to inducing them to bloom, I wasn't sure if there was a set time frame like 6 weeks below 45'F or something like that.

Cheers.
