Hormone rooting powder question...

[Kelo]

I was thinking the other day would/could hormone rooting powder induce keiki bearing plants to produce keikis or would it have no effect at all? Given the purpose of HRP, to produce roots, might it stimulate the plant to produce a keiki too?

Interesting question, I've been wondering the same thing. Although my initial knee jerk thought would be no, I just don't know.

Rooting powder or solution will induce roots.
I have no experience using this to produce keiki.
If you want keiki, I would use Keiki paste which is for sale from Carter and Holmes on Amazon.com. It is relatively inexpensive imho.

I've heard that many rooting powders (at least here in the UK) are too strong for Orchids and actually inhibit rooting as a result. I certainly had no luck trying one on a rootless phal.

You can get KLN from Peter White in the UK which is good for orchids.

However I have no idea if it works for getting keikis. I would have thought it was a different hormone but I don't really know.

That's what I was thinking since it's marketed as keiki paste or hormone. But of course being in marketing myself, I also know that it may be no different, lol...

Thank you for the replies. I just thought that by encouraging the plant to bear roots might have the added possibility of producing a keiki. I added HRP, about the size of a match head, to two litres of water since I thought that HRP, too, might be too strong for orchids. Keiki growing isn't that important to me but it was something that just popped into my head. thank you again.

I've seen it used as a fungicide on any cuts to good tissue.

I dont think it would do the same. Cytokinins are the hormone for root production, whereas IAA would be the pgr for the offshoot growth.

1) Powders are too concentrated for orchids, as has been stated.

2) They are also essentially insoluble in water. The idea is to coat a woody stem, plant it and have the hormones stay in proximity to it. If they were soluble, they'd vanish into the soil, migrating away from the plant.

3) Rooting hormones are auxins. Keiki-inducing hormones are cytokinens. And they are antagonists.

Brilliant, thank you for the information.
