I think it depends on your lighting. I had borderline medium/high light and mine only got like 3-4 inches highest, most were less.

It can grow 6 to 8 inches in due time. I filled a 10g with it. Just used dirt and a cfl bulb. Grows like a weed. You can trim it if you like.

I just about a month ago cut back the whole ten gallon tank. Reduced it by more than half. It recovered fairly quickly. No real problems to speak of.

Do you mean removing full nodes or cutting leaves? The leaves definitely will not grow back once cut.

Most of mine is about 2-4 inches but some is getting up to about 8 inches or so.

Really cool plant, it's a like a lawn in your tank.

I would like to grow dwarf sag and trim the leaves once it grows too big. I keep reading about people saying the leaves grow back and some say they don't. Now I'm confused. :(

IME, in my 10G with 2 CFL 13W bulbs, they grow small and carpet-like. In my 25G 16" High tank with 4 T5HO bulbs, they started getting really long. Reached the surface and then flowered - small white flowers. Its the exact same batch in the 2 tanks but way different growths.

I have some that reach almost 10". I swear they have some Val in them :)

You can trim the leaves. They will just yellow and decay like others have stated. Better to pluck em.

Tall, I've had a few leaves reach the top of my 24" 90g tank. Depends on lighting and other conditions. Old plants grow longer leaves as well, new plants stay small (under 6 inches) for a few weeks.

I just setup a 10G tank that is dirted and with 2 CFL 13W bulbs. I just want to make sure, but is 2x13W bulbs okay for low tech?

I am growing Ludwigia Repens, Java Fern, and Anubia Nana Petite. Here is a picture of my tank.

I want a lawn of my own, lol. Any tips that you could give as to how to create a lawn/carpet with that plant?

I have a bunch of these in my 75 gallon. The leaves will not stop growing really. I routinely have them reach the surface of the tank and then grow sidways. I cut them all the time and they always grow back. Sometimes I cut ones at the surface down to about 6 inches. I've had the same group growing in my tank for a couple years now. Grow, cut, repeat.
