Ludwigia growing sideways.
I purchased a few bunches of Ludwigia and Moneywort at the same time to put into my 75g. This was almost 2 months ago now and my Ludwigia is barely growing. I've already had to trim my Moneywort twice and the Ludwigia as barely grown at all. My LFS said they should have about the same growth rate. Now I've noticed that the Ludwigia is starting to grow sideways. Why is this? I've included a picture.

there are many many diffrent types of Ludwigia, that specific species you have "Ludwigia repens" has a very common tendancy to grow horizontally. most will take the motherplant and arch it (anchor the top of the plant in the substrate also) thus forming more of a bush like appearance then a typicall stem plant apperance. the daughter plants tend to grow in more of a upward stance but still have that chance to grow sideways. that plant should be growing pretty fast, if you are not seeing any new growth or fast enough growth its a lack of co2 or ferts. if you have had it keep its color for 2 months its not your light that is sub par but your co2 and fert dosing. i would slowly up your dosing, and if you start to see algae appear either drop back the dosing or introduce more co2 to speed up plant growth and stop/slow down the algae growth.

I'd like more data, as I'm a bit confused. Are you saying there has been no growth in 2 months? Were the stems bent as in the photo when you planted it?

What is your light? And fertilization?

There has been a little growth but not much. The stems were straight when I planted them. For lighting I have an Aqueon T5 NO fixture with one 6500k daylight and one 6700k colormax bulb. Fertilization is Flourish Comprehensive twice weekly.

If that happened after planting and it isn't all new growth... is there a bit of current in there?

Not much at all.

do a google search on Ludwigia repens growing horizontal, you will find many sites refering to the plant and its horiznotal growth. theres people that claim its from to much light too little light or too much curent. the one theroy that holds the most water with me is that the plant just tends to grow that way.

Mitch may have it. I noted in Kasselmann that the stems will grow "creeping" emersed and vertical submersed. But Aquatic Plant Central does say,
When lit well, the plant will grow at an angle over the substrate instead of straight up.
Maybe the plant gets mixed up.;-)

I will do a little research tonight and see what I come up with. Thanks for the responses everyone.
