SUbmerged plants - immerged - terrestrial

[AquaObsession]

This thread is oso posted in "aquascape section" on the website. however, i re-post it here, hoping to get some accurate answers. Kindly advise....


just a general wondering...

I bought several plants from Teo Aquatic recently. Some of them were taken from pool of water, others were not growing in water. However, i know a few plants that they cultivate in terrestrial form but which can be submerged plants.

My question is : If at farms they grow plants in terrestrial form, does that mean they are the "terrestrial" plants?? or terrestrial plants are just plants that is not meant for water??



I saw the terrestrial version from his cultivation, and the submerged version in his display tank....they look different, but both healthy...


What i meant was.... are immerged plants that you find in tank, the real ones, sometimes cultivated on terrestrial form,,,, eg, plant it without much water, but the environment is very cool, very muddy soil, and roof dripping water...I think they do that for commercial purposes.... does it mean that after conversion the plant can only live for a few weeks or months???


eg i saw glosso being cultivated outside water, even though the "pool" (growing area) was very wet.

Um, I have difficulty understanding your post

Most plants in our hobby are semi-aquatic, meaning they can grow both in and out of water. Swords, cryptocorynes, hairgrass, Anubias, Java fern etc are all good examples.

The farms grow plants emersed because they grow faster this way, and they can be kept algae-free, and handling plus transport will be much easier, as well as a whole host of other reasons.

Terrestrial plants = plants that cannot survive in water.

Sorry, I was also confused by the terms that I used, but your reply did answer the questions.

I thought terrrestrial meant Emersed, hence hte root of all confusion.


Is there special technique to make the emersed cultivation adapt to its new underwater life faster? Will all the leaves die? Anything to do to fasten thier growth or adaptation?

I am a bit worried since I planted two whole tanks (see new 4 feet tank in aquascaping section + my own personal tank) with both plants that were cultivated underwater, and plants that were cultivated in emersed form.

either form is good a long as the plants are growing healthy.

however, in "our" case of planted tanks you really can't help the emersed forms from shedding their leaves eventually as this is how they convert to submersed form.

some plants do massive leave melting and some do it over some time as new submersed form leaves grow. it all depends on the species. since you have a new setup you just have to be a little more diligent in remove rotting leaves. otherwise its just up to time to make good for all your new plants.

Like celticfish has given a good post

Personally I trim off the big old leaves from plants like cryptocoryne since these will rot anyway. It also sort of lets the plant know that it has to transform.

squee,
now that you mentioned the crypt thingy i remember reading or being told by one of the forumer's that he snips off all the leaves till there are three or four max. is this what you do for your crypts?

i haven't tried this but i go the other route. i'm ruthless with the roots, as they usually rot totally, and keep the leaves. i cut the leaves at the first sign of melting.

hmm... maybe i should try an experiment for this...

I trim about 4 oldest leaves and leave the rest.

[celticfish]

thanks for sharing your method!

What about the other stem plants that we get from Teos?
Most of the plants are really marsh plants... So are emersed forms... Should we trim away the emersed leaves and leave a bodak stem in the tank? Will it be faster than leaving those leaves in it and wait for it to rot and grow submersed leaves?

[Justikanz]

I think it should be better to trim away the older leaves but retain some leaves at the same time... The botak stem might not do well...

Definately not a bald stem The plant still needs to "sense" light and changing conditions.

[valice]

That's true... No leaves how to photosynthesize??!! Thanx...
