Thank you & INTERESTING!!

You confirm that -

1. Terrestrial aroids in pots are drowned when submerged?
2. Spathiphyllum wallisii & like others in pots may already have some "water
roots"?

Free aquatic culture is so much easier, flexible, non-labour intensive &
trouble free than growing in darn pots with composts or even "hydroponics"
with aggregates in pots!  For the next phase of the Spath operation, I need
to find out ASAP just what part water in simple aerated ponds can play
rather than using composts in pots.

You wrote
!it is possible to propagate plants so that they grow from the START with
water roots. A species may not be able to tolerate being pulled out of a dry
pot and getting drowned; but if propagated so a baby plant grows water
roots,
that species will be able to grow perfectly happy with its roots submerged.
(As you have noticed, some species don't care either way; but most do.)
Instead of attempting to submerge a plant, have you tried propagating a
specimen of the species in water?"

>>>>>>>>>>>>>>Potted Spathiphyllum can obviously be divided for propagation
but the "baby plants" have roots.   Without roots can they be viable?   If
one puts say some Syngonium/Monstera/Philodendron stem cuttings with dry
aerial roots in water, they do develop "water roots" readily.  (I do not
know if & how "aerial roots" are really distinct from "normal" roots!.)
Soh -

I will experiment more!

I do not understand why some de-potted Spaths, BARE roots, when immersed in
water which is strongly & continuously aerated, do badly?

Do land roots take in gaseous oxygen or oxygen from surrounding water?  How
important is firm anchorage?  Is it important for roots to be in darkness
when submerged?

How many Members already grow their "land" aroids in water?

Any other ideas please?

Ron
