Hormex has a liquid formula that is used in hydroponics that might prove useful.
thank you.. I’ll check it out and see if it works

I read somewhere that the rooting hormones we use for stem cuttings do nothing to stimulate growth from roots. As someone pointed out recently, roots already know how to grow new roots.
I hope you will try some side by side trials and let us know the results of anything that you try.

Guess that would have been me.
I would be keen to learn about stimulants to get roots to develop faster though. Vitamins and/or sugars may help trigger roots. Prooving this is however tricky on a once-off basis.
For yews I use a pine-extract sold commercially which strengthens needle-activity in conifers, not sure what it is called. Not sure whether it really does something. But according to the label it should so..
Probably next season I’ll try it on a few young Ponderosa and see what happens. I’ll reduce they’re root mass drastically and apply hormone water to half of the group. Within a few weeks results should start showing.

As I understand it, applying rooting hormones to roots is mostly futile. Roughly, The hormone acts as a switch to turn on rooting in plant tissue. Roots are ALREADY roots, so the switch is already pulled there. Adding hormone to stem tissues, like twigs and branches can help those root, however, since they're not root tissue already...
Thanks... Yes this was discussed above. This is why I'll be doing an actual expierment with the process next spring. My hypothosis is, that if root tips/mass have been cut/reduced drastically, it may accelerate new root growth.

Based on what? It is not the root tips making the hormones
Hormones are tricky things. The wrong concentration and they are mis interpreted.

I personally enjoy the horticultural side of not just Bonsai but all tree and garden cultivation. I’ve been able to root trees from cuttings others said was impossible (Larch). I air-layer quite a bit, just got a Japanese Maple to produce a root ball in 2 weeks. It’s now cut from the mother tree and growing on it’s own.
In regards to Indole-3-butyric acid, I have 99% pure IBA and can dilute it to any percentage needed.
No skin off my back if it fails, I enjoy the process. I have plenty of trees willing to be experimented on.

Thanks, interesting post. But how do you dilute the 99% pure IBA powder?

For collected trees I've found warmth in the root zone stimulates root activity well, as well as an open media. Canna, a hydroponic company make a product called Rhizotonic which is an extract from marine algae that is supposed to stimulate rooting, used on it's own, not with fertiliser. I'm trying it this year but probably won't be able to isolate results.
IBA can be dissolved with Isopropyl alcohol or similar then added to the required amount of water.

If you're building out a research project, I'd incorporate Canna's Rhizotonic (I've used it and wasn't wowed), Kelp, and a heatmat. I suspect bottom heat will be the biggest factor in stimulating root growth.

Bottom heat has been the most effective root stimulant I've found. "Heat" is a relative term. Simply leaving the pot exposed to morning sun can warm up the soil enough to help. There are other artificial ways to do it too--heat mats, etc. All the hormone potions I've tried don't really do all that much. Some can inhibit root growth if used excessively or incorrectly...

With the exception of common fertilizers and micronutrients, hard data on the effectiveness of most of these supplements is impossible to find. People believe they work, but no one really takes the time and effort to demonstrate that. Take your favorite supplement and treat 10 identical plants with it, and keep 10 others without it. Keep them side-by-side and otherwise treat them identically. Note the results in terms of root growth, plant size, or whatever, and report back.
Most of us don't have the resources to be able to do these experiments so we do what makes us feel good. Nothing wrong with that, but in most cases I suspect it's just a waste of money.
