Propagating Cryptocoryne... did I do this correctly?

[chkltcow]

I have a Cryptocoryne Undulata that has gotten HUGE since I put it in my 29g a few months ago. I'm setting up a new nano tank and wanted to put some of it in there. I know that you're supposed to pull up a runner that's not attached to the main root ball, so I started pulling a bit on some of the outer stems and all of them felt pretty firm. Finally I found ONE tiny runner that came out with roots attached that seems like it wasn't part of the main root ball. I pulled it out carefully and moved it to my other tank.

Just wanting to confirm... this is the correct way of doing it, right? Is there any other easy way of propagating crypts rather than pulling until something feels loose?

I think I'd have done what you have done, usually it sort of feels like you are peeling them apart and it looks quite natural what a little plantlet looks like each time.

So I just went to the bedroom to check the tank, and there's new growth since this morning! That little green shoot coming up towards the camera is new!

Okay, I feel better now about not screwing it up.

Normally you cut the rhizome with a single sided razorblade or sharp knife. However, you have to make a clean cut and monitor the plant for infection afterwards. Sometimes the wound doesn't heal properly and the rhizome rots from the inside and kills the plant.

If you can find plantlets, the that s a safer way to go.
