Cryptocoryne growing above surface?

Has anybody had any experienced growing Cryptocoryne emersed at the aquarium surface attached to wood? Tried this with Java Ferns last week but the shrivelled up - I think either I needed the rhizome submerged or was just no good. The wood has terra tape attached. So far I just have them resting at the surface with roots underwater and the leaves have been OK. Do the roots tolerate glueing to rock?

They are just plantlets that came out from the soil so no big loss either way.

Hi
You can glue Cryptocyrne rootstock too rock, wood ......this best done when the wood or rock are dry.

The rhizome/roots must be submerged attached to the hardscape.
The leaves could melt, if out of the water but they may/could grow new ones if provided with enough nutrients, co2, light, humidity!

A couple of years ago when taking down a aquarium in summer l put a lot of java fern in plastic containers inthe greenhouse some began to grow emmerse as a result of l think the high humidity. Got Lilaeopsis-novea zealandia doing the same

Definitely need high humidity to grow Java fern emersed.
Crypts will grow out of water quite happily as will a number of so called aquatic plants...

Thanks guys. Winter here at the moment so the dry air must have been the issue. Totally different story in summer...

Unfortunately absolutely no control over humidity since our windows are louvres without glass.

Will try the crypts.

Microsorum is extremely sensitive to air humidity i also experience them as very sensitive in a closed terrarium setup. 1 little mistake of neglection air humidity 1 week to low and they already show unhappiness... Outside a greenhouse, I deem this plant impossible to keep. But never say never...

Bolbitis heudelotii should be a possibility, i remember an Amano scape with a rather large Bolbitis growing emersed from the tank planted on DW. All though i failed myself several times... It seems to be a very lengthy process to make this plant transition to these circumstances. It also might be that the gallery where Amano kept numerous scapes has a tad better air humidity for this than the regular living room with 1 tank only. But that i don't know. Only know he did it and i failed to replicate it... :)

That's the con with pictures on the internet, making it all look easy but it doesn't tell you the complete background story. In many cases the keeper doesn't know it all too...

I monitored the air humidity 2 inch above my open-top tank for a very long time... In my case, it never was any higher than 45%. And this is a parameter you actually should know to give you an idea what your limitations are. Not only each tank is different i guess it also goes for each room a tank is in. I seem to have a rather very dry and drafty house.. Get yourself a small electronic Hygrometer and see where you're at... The better air humidity you have to more options in being successful you have. 💪

Huimidty pretty much as low as 0% in winter and as high as 100% in summer :)

@LondonDragon has/had a Microsorum sp. growing emerged from the HOB filter hanging at a shrimp tank... A terrestrial variety, not the M. Pteropus... I forgot but i think to remember the common name is Kangaroo Fern. that would be the Microsorum diversifolium if I'm correct. :)

When it grows happily from a hob filter, it might do on a merged piece of DW as well. :thumbup:

Several from Adiantum sp. (Maidenhair fern) are also popular ferns for this type of growing. In my experience they are rather light senstive for true success...

I have crypt growing from wood and it’s not near the surface
I sprayed it every time I thought about it
It had to be sprayed a lot at the start
I also sprayed it with Rhizotonic
Now it gets sprayed once a week
The humidity must be very low as you may be able to see the leaf from a Amazon sword which broke the surface has dried up

I just glue it directly to the top of the wood a couple of years ago
