Was wondering if anyone had any good tips on how to transition plants that have grown emerged back to growing submerged. I have a rotala spcs. that is going crazy out the top of one of my tanks. I trimmed it back, and figured that the best thing would be to stick the trimmed end in some water and gradually resubmerge it. Well, I wound up with a lot of dead rotala trimmings(though this could have been from a lack of light, as they went from sitting literally just under the fixture on the tank to setting in my window sill, still strong light but nothing like the fixture), no big deal because before long, I am going to have to do it again, but wouldn't mind getting the next set of trimmings to work out so I could offer them for trade . Thanks for any help.

I would think if you are having trouble from emersed to submersed I would try growing the clippings on the window ledge with just the ends in a glass of water until some roots form.

your water parameters for the submersed setup all need to have proper nutrients, light, and co2 though

just plant them back into the tank they came from.

Nearly all plants bought from the big nurseries are grown emersed and acclimate to our tanks just fine. What you SHOULD do is trim before they're jutting out of the top

My rotala and moneywart are a pest to reacclimate to the submerged growth.

If you don't mind blocking light from the rest of the tank, and the ugly floaties, you could try floating them for a while and see if some roots appear.

I try some of these out next time, I know I should trim them more often, but with an open top setup, it just looks amazing when the leaves up out of the water start turning a near burgundy color.

if you like seeing them out of the water like that, but have problems re-acclimating them, then you have to get used to one thing.... throwing away some clippings
