Just thought I would like to share a method for propagating comfrey that I found quite by accident but is very effective.
All I do is keep one well established pot of comfrey and simply sit the pot where I intend to grow more comfrey, wait for the roots extend into the soil from the pot, move the pot to the next spot and within a few short weeks your comfrey root "cuttings" will spout and your done.
So easy I love it!
I am sure it would work for most plants that grow well from root cuttings.

Yeah I've had that happen with comfrey too.
Goji, Agaves (rhizomes rather than roots) and a few others too
I took it a bit more seriously when the Poplars did it in the shade house.
they're still there growing strong and I run the risk of having them 'become' the shade house one day

I've done the same thing but in reverse...
ie. using pots to do aerial layers.
putting the pot on an existing plant, induce root growth with in the pot, then take away a new plant and leave the parent there.
rather than place the parent, allow new roots to grow into the ground , then remove the parent and leave the new plant behind.

Marcotting (aerial layering) woody plants....
not comfrey, I was half asleep and possibly half tanked as well when I posted that.
but for marcotting (woody plants) , remove bark to expose cambium layer.
use rooting hormone if needed depending on species.
I may not have been very clear,
reading it now it looks as if I was talking specifically about comfrey,
but I meant plants escaping pots ( or getting into them) generally.
sorry 'bout that

I'm still not understanding how you get the roots into the pot ;-) I understand the basics of aerial rooting. Are you talking about big plants so the roots are long enough to get to the top of the pot?

For aerial layering in plastic pots I'll use 2 identical plastic pots.
Cut a hole in the bottom of both of them the same size as the stem diameter.
then cut a slit from the hole to the rim on both of them.
it can be straight but I prefer to make a helical split clockwise on one , anti-clockwise on the other.
prepare the stem to be marcotted in the normal way ( rip the barkor cut and remove bark, apply hormone if desired etc.)
put the two pots on the stem one at a time with the pots eventually one inside the other.
the idea of the helical (spiral) cuts is that they will only meet at one point and not lose the potting media.
Tie a piece of thick twine around the stem on which to rest the pots weight.
Fill it with potting mix/soil etc. and keep it moist til it takes root.
when the rootsystem is developed enough ( roots appearing near drainage holes of pot)
detach from parent plant.
I've used this method for a few different plants, including a bamboo (Nastus elatus).

So the two pots are on a living plant stem still attached to the parent plant?
And they are facing each other ie open end to open end, to keep the potting mix inside?
How do you know when roots have started to grow? I gather you then chop the living plant stem as it enters the bottom pot, and in between the 2 pots and grow the cuttings on for a bit before transplanting.
And what sized pots?
I'm gunna have to give this a go just to see what happens... Will it work on an avocado? I could do with another tree...
