rooting hormone query
Hi group,
Sorry to bother you guys with another question (I looked on the net and couldn't find an answer), but when one uses rooting hormone (ege 0.04% IBA..etc), how is the stuff absorbed into the plant anyway? I presume roots. But how about just normal plant tissue....can one apply it to leaves and get the same result? What if one wanted to use it to get roots out of a nodal keiki that hasn't rooted yet. Can it be applied just to the base of the node? How long should one wait in order to judge whether the hormone has done it's job? TIA Cheers, Xi |

This is an anecdotal response, but it's the best one you've gotten yet. Oh
yeah, and the "only" one, apparently. First, you'll want to dilute that concentration significantly. For a 0.04% starter, I'd recommend no more than about 0.5 ml/liter. Yes, the hormone is absorbed primarily through roots, but it can also enter the plant through other surfaces. I guess that's why it works when you soak a rootless plant. If you subscribe to Alan Koch's (Gold Country Orchids) thoughts, the underside of the leaves are the preferred surfaces. I would guess that applying it to the base of a keiki would be OK, but you'd probably want a formula that stays put like Keiki-Root from Plant Hormones Canada. Apparently the application of such hormones spark root growth systemically, not locally, or we'd see roots growing from many surfaces after a soak. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Artwork, Books and Lots of Free Info!

Hi Ray,
Thanks for your reply. I checked the label, and it's actually a 0.4% solution of IBA + fungicide. But it didn't say that it should be diluted! In fact, it says dip the cutting and then just stick it in a pot and wait. Are orchids more sensitive to these hormones than other plants? Will the undiluted solution damage the plants, and how long should one wait for results? TIA Cheers, Xi Ray wrote: This is an anecdotal response, but it's the best one you've gotten yet.

Yes they are!
"Dipping cuttings" is likely referring to woody cuttings from shrubs - much more in need of a strong boost. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Artwork, Books and Lots of Free Info!
