Ludwigia Inclinata Cuba emersed to submerged...

**plantz** · 15th Apr 2004, 14:38

How long would it take?? And what is the best method?? Got Ludwigia Inclinata Cuba from teo. plant in my tank from 4inch till 10inch in a few weeks. Trim the top and plant the top in again from 4inch, soon to be 10inch but still look like emersed form. Why?? It's under a 55w light with CO2, base and liquid fert. Or do I leave the bottom stem and trim the top??

Please advice. Thank you.

My cuba has transformed into submersed form in 3 weeks time. Initially it grows tall but soon you will notice it transforming into submersed at the top including many new submersed side shoots. I have cut the top part and replant into the substrate becoz it was reaching the top of the tank already. Be patient....

Otherwise, you can trim away the top portion and allow new shoots to grow which will definitely be of submersed form.

I got the same problem as you from a batch of Ludwigia sp. Pantanal (?). It was submersed when given to me. But I forgot to trim it as it reached the top of the water. So it turned to emersed form. I cut it and replanted. It never got back to submersed form for a long while. Even the bottom half grew emersed like leaves. It is as if the tip had told the rest of the plant to show emersed leaves after it reached the top. Weird. I gave up on it.

Now I have confirmed (from someone who bought it from Tropica at Aquarama 2003) L.inclinata "Cuba" and it doesn't have this problem. If interested, I can save you some cuttings to try.

unlikely due to different strain, I planted emersed form of L. pantanal in my 6ft, 2 weeks ago and they showing signs of submerged leaf.. also notice the transformation takes awhile and the nodes on the plant increases. Previously 2 leaves per node, now there is more

I got my emerse free from Teo, one of the guy gave me few stalks. They look quite nice with yellow flower and green leaves. Two big leaves on each side and scatter far apart. That guy told me it will start to change by 2 weeks, but my took almost 4 weeks to get the new leaves. I have keep trimming and replant and now (after 2 months) the leaves are very thin,long and quite bushy. The top leaves show some red and looks very nice.

Borrow the picture from ADA contest (Erik Leung). Looks very close to this but less bushy .

Neon, it takes time for the plant to adapt submersed. The guys from Teo gave you an estimate time. It also depends on your tank conditions as well. Be patient

**plantz** · 16th Apr 2004, 01:35

Thks guys,

Must admit, the emersed form is very nice. However still prefer the submerge ones. And Mr gchoo, I never mentioned about throwing away

. Mr juggler thks, if I need the cutting will let you know.
And thks to everyone else for their advice. Well patience is the thing I am learning to adapt in this hobby :P . Let's wait and see....

Sigh - I gave up before the 2 month period. Mine showed emersed leaves for more than a month. Maybe next time try again.

I just checked the Tropica label, the variety sold at Aquarama 2003 is Ludwigia inclinata var. verticillata ("Cuba"). The leaf tip is yellowish with some tint of red. Just like the one in Erik's photo in the above link. I have this plant and it doesn't show emersed leaves so quicky even it is growing horizontally on the water surface.

However, the Ludwigia spec "Pantanal" seem different. It is more reddish at the tips and overall.

These are different plants, right?

Tropica just changed the latin name back to the original which is Ludwigia sp. 'cuba' http://www.tropica.com/productcard.asp?id=035C

yes KF, the pantanal and cuba is defintely different subspecies

Simon: Thanks for the corrections and confirmation.

BTW - Teo has Ludwigia inclinata at his farm. I found it to be a rather difficult plant to grow. It can grow well initially but fades off later. Also, it grows too fast if conditions are right.
