Propogation

[Mcannelis]

How do you propagate the following.

Tropica fern new
Water wisteria new
Water onion( new leaves are budding off old ones and it got pretty tall recently)
Amazon swords ( new leaves coming from roots)
Anubias( same as swords)
This is whats been happening and I was wondering how do I propagate and put in more than 1 place

I can only speak of the ones I have done myself:
wisteria simply cut the stem. I usually clipped the 'branch' close to the main stem. Then simply replant the clipping.
Anubias simply cut the rhiozome with a razor and reattach where you want. I've heard that as long as there are a few leaves and some roots, it doesn't matter how small of piece you cut off.
