What would be the smallest by length cutting that still can be rooted?
I see 6-8 inch average length. How about 2 with 2 nodes?

yep. even one node

Great! And what would be the best rooting method for a one node little creature?
Moss, root riot cubes, baggies, else?

Ah! Willwall, that's encouraging! 

I’m just now hatching out my first cuttings and no expert but, the little one or two node cuttings have been surprisingly easy.   When preparing my first cuttings for the rooting box, several had to be trimmed to fit the plastic shoe boxes being used.  Somewhere on the forum I had read with interest about the one node wonders.  With that posting mind, I just threw those left over pieces in too!  To my surprise they proved to be more vigorous than their 8” companions.

Oh yeah, I am using sphagnum moss as a rooting medium.  I’ve tried the plastic bag and planting medium methods, with limited success.  Maybe I was impatient and didn’t give a chance but, it seems that I can keep better control of moisture/humidity with sphagnum.  So far, depending on cultivar or source, my cuttings are taking about six weeks plus to cup.  The shortest only four weeks!   Also, thanks to all the wonderful tips and advice on this forum, I’m running 100% rooting (so far) and NO gnats………… yeaaa!

Regarding reply my reply above, the photo attached is a one node that came out of the box today.   It is an Italian Brooklyn White @ 33 days.  The first of the one or two nodes planted (a week ago) have yet to push out anything green but, growing roots like crazy.  Something should pop soon, I’m thinking…..! 

Wow! Thanks for sharing! I will get some moss for my little guys to try it too. For larger cutting I like using paper towels until I see roots appearing and then move them into cups with cactus mix.

That's awesome Jack!  That is a good healthy cutting.

Once you have roots I'd fertilize.  Those small cuttings don't have a lot of energy.  Be sure you're using houseplant strength fertilizer.  For miracle grow that's the small spoon in 1 or 1.5 Gal - you have to read the directions to see what it's designed for.

more than 1 node but just about an inch, Black Madeira

Strong work!

rcantor suggested miracle grow in the dilute strength solution.  Walmart sells a similar product called expert gardener.  Both are a 24-8-16 formula...which Al Tapla recommends.

I use both.  Just depends on where I happen to be shopping when I run out.

JR, this is a case when fig growing becomes  an ART!
Those little pieces look as if you send them through a shredder by an accident (a spam envelope with a cutting inside?) :)

Now I really want to try mine! I set some up in the Root Riot cubes but inserted the cuttings.
Did you use any growing hormones?

greenfig- The real art will be actually getting these to grow!  I hope you have as much fun as I'm having and I can't wait to hear how yours turn out.  Please keep us informed!

And no, I didn't use any growth hormone with these cuttings... just a lot of TLC and a smidge of obsessive/compulsiveness :)

Just wanted to give an update on my single node cuttings that I've been playing with.  I decided to up-pot today because my most hopeful one appears to be dying (am now hoping for resurrection for it!)...






This next pic is my partial node that is not in the best of shape but seems to be hanging in there.  Notice the clear globule under my index finger (second time I've seen one) that has surfaced from the Root Riot cube.  I think it may be one of those water-retention gel things (??)....  (what are those things called anyway??)...



And another partial node cutting that I up-potted today....





And this next guy (which is a full node) is going crazy-  I had to redirect the root with toothpicks to get it to go back into its own cube....





All of these seem to have brown discoloration in the bark, as if they're using up all of their energy?  Maybe it's moisture decay? 

JR - looking good.

(But I have to ask -- you said "and a smidge of obsessive/compulsiveness :)"... is it truly possible to have just a smidge of that?  :-)  :-)

The pics look like you've got some great root stuff happening with those tiny bits of scion.  Good luck getting the tops moving too.

Mike

does anyone have any long term follow up on these tiny experiments>? :)
looks like we can take cutting from ebay and resell them .....

I started rooting of some tiny 1-2 node cuttings in the cubes but it is too early for any photos yet. I'll update as soon as there is smth to see. The good news at this point is that they still look alive! Not dry and not rotted. One 2 node largest cutting is leafing out but it is about 2 inches long so I wouldn't consider it a tiny one.
I think the success depends on the cutting freshness. Right from the tree will root almost for sure (my observation) 

you know somtimes in 2 inches i find 4 nodes and somtimes even 6. as i know 2 nodes above and below ground are enough.

i think that it would be making easier packing and mailing these little folks than a 8 inch cutting.
also the shipment will be much cheaper.....

Well, the shipping will not get much cheaper if you mail a few. In the US, to mail some 2-4 cuttings via the first class costs about $3.20. You may go down a buck, if you are lucky. If you mail a lot, a fix price Priority Mail makes more sense. 
On the other hand, the short cuttings have less energy and I think it will be harder for them to take off, esp. if they are not super fresh.
From what I see, 5-7 inches is about the shortest comfortable length, you can bury them deep enough for a successfull growing.

I started down this road of single node rooting as a "fun" experiment, born out of 2 things:  1.  I'm notoriously unlucky (if it CAN go wrong it DOES) and 2.  My dogs damaged my 8" Nero trees (in an attempt to eat the Bounce fabric softener I gingerly placed on them to ward off gnats), leaving the Neros precariously close to death.  Since I'm always having to CMA (cover my a_ _) I thought it'd be great if, when faced with an emergency - like the incident Nicole had with her dog mauling her scions - I could recover a scion with only 1 node remaining.  It's been a fun adventure and I'm happy to see that this may work if/when needed.  And honestly, I didn't think I'd have this much success and regret not being more diligent in my efforts :)

Since I'm still learning as I go, my favorite rooting technique is sp. moss since it seems as if the roots are a bit more plentiful and robust, and the transplanting into cups seems to be more successful.  Although, the Root Riot cubes do appeal to my "smidge" of OCD (okay, I lied, it's a bit more than a smidge...) and my need to physically handle the figs.   I don't know...it may be the other variables I'm manipulating that makes the success of one over the other... but still playing around with it.  But I do agree with greenfig that 5-7 inches seems to be the (IMHO) minimum comfortable length for rooting.

It's kind of like the difference between those who "vacation" and those who "travel".... for some the joy is in the journey; for others its in the destination!
