Hi,

Having no success in establishing a carpet with Micranthemum Unbrosum (Montecarlo), I switched to Echinodorus Tellenus, considering it is easier to form a carpet with it.
However, instead of spreading, the plant is just growing tall, with some leaves around 5 inches long. The plant was grown emersed when I had bought it, as it came in a pot.
I have tried trimming too, but no success. Is it an issue with the plant or should I be taking care of something else?

How long have you had it? My experience with it is that it doesn't start to send runners for 4-8 weeks until it gets settled. Also, if the leaves are that long, perhaps it is not tenellus and may be some other species. I have E. "Xingu" and the leaves are around 5" and definitely not a small plant.

A pic of your plant will be helpful.

i have tenellus under very poor lighting. even the mother plant is not more than 2-3 inches high.

Mine struggled for a couple months, it grew but didn't look all that great. I think the roots have finally spread enough and maybe hit some root tab spots because it is really taking off now.

Hi kanishkster,

Are you sure you received Echinodorus tellenus (now Helanthium tenellum / Pygmy Chain Sword)? Maybe you received Micro Swords (Lilaeopsis novae-zelandiae) instead? I grow my Helanthium tenellum in fairly low light (PAR=25) and have not experienced excessive leaf length.

10 gallon; PAR = 25 (2 X 10w CFL); No CO2

Its been around 4 weeks. May'be I should wait longer. Other than being long, some of the leaves are around 3mm in width. Here is the pic:

Bump:
How much light is there? Many carpeting plants spread best under higher light.
Light is 36W CFL, around 18 inches above the substrate. Photo period is 7 hours. Plant is growing on a good rate, its just that growing tall instead of sending runners.

Hi kanishkster,

It looks like Helanthium tenellum / Pygmy Chain Sword to me. I agree with longgonedaddy it may just need more time.

Thanks for confirming. I will wait.
Can you please advise when and how should I be trimming it? I have observed when I trim it half (like grass), the leaf does not grow further and instead starts melting.

Hmm..as recommended by others, I would wait for few more weeks and see if runners appear. By the way nice tank.
Would you mind sharing names of all the plants you have in it?

Thanks OVT. I will take care of it now.
In case I have trimmed all the leaves of a plant, I hope it would still recover?
Hi kanishkster,

It may recover if all the leaves melt; if you don't see new leaves in a couple of weeks it is probably not going to make it.

I have some, probably took a while to get going. They need Root Tabs. I have a MiracleGrow substrate so I don't use them. I do 1/4 IE ferts too. I have a 10 gal. with two 10W CFLs hanging 8 hours a day. Once they took off they really took off, going all around the tank walls and in towards the middle. Yours are much more closely planted than mine, even as they have grown.

The height seems about normal. BTW, do you have enough light? I see some yellow on some of the leaves in your tank. All I can say is it's not normal.
