Mordecai13 Posted Thursday at 08:47 PM Share Posted Thursday at 08:47 PM (edited) Hello all, I bought 2 ludwigia repens just about 2 months ago, and I’ve come down to the last couple flowers of them. The first turned brown and died kinda quick but this one in the image has stayed alive. I recently took them out of the weight to replant them individually, is this the correct way to plant them? How soon should I expect growth? I have an aquarium co op root tab in there also and have been dosing easy green. Thanks!

Guppysnail Posted Friday at 01:28 PM Share Posted Friday at 01:28 PM I had luck reviving my faltering ludwigia by allowing it to float at the surface for a few weeks. 3 Link to comment Share on other sites More sharing options...

Quite unscientific, but I think they'll do better with a little space between them for root growth. That said, I sometimes get lazy with stems and stick 3 or 5 in a bunch together. But I think your way is better. 1 Link to comment Share on other sites More sharing options...
Pepere Posted Friday at 10:34 PM Share Posted Friday at 10:34 PM (edited) In my co2 injected tank with 30 ppm nitrate dosing, and high light I shorten my Ludwigia Repens about 4 inches every week. It gets pulled, I cut off the bottom 4 inches and it gets reinserted in the gravel. Just water column dosing, no root tabs or nutritional substrate. In my 17 gallon fish bowl I do not inject co2, I dose Easy green to get nitrates around 15 ppm, I have aquasoil under the inert substrate in this tank, and the lighting is much less. It takes about 6 weeks for the L. Repens to grow 4 inches… I do insert each stem a half inch or so away from each other and do not use weights. All of my tanks run at about 3-4 degrees of GH and 1-2 degrees KH. I have very soft tap water that I supplement with Seachem Equilibrium to raise GH and also provide potassium and iron… L Repens has proven to be a very easy plant for me that seldom ever had algae grow on it before I got the Algae monster under control…. On the right hand side of the bowl is L Repens. In addition to growing much slower without supplemented co2 you can see that the tops have less reddish blush to them and the leaves are smaller. Here in a co2 injected tank you can see the L repens center stage in the background behind the pink flamingo crypt reaching for the surface. This photo is about midweek after trimming shortening. Within about 10-12 days the L repens would reach the surface. Edited Saturday at 08:42 AM by Pepere 1 1 Link to comment Share on other sites More sharing options...
Pepere Posted Monday at 11:47 AM Share Posted Monday at 11:47 AM @Mordecai13, I thought you might like this photo I took today showing the morphological differences between the L. Repens grown in a high light, high fert co2 injected tank vs the one grown in moderate light, moderate ferts non injected tank. The specimen on the left comes from a non injected tank that takes 6 weeks to gain 4 inches of height, the one on the right is in an injected tank that grows about 4 inches a week. the plant in the injected tank has fewer but bigger leaves and a bit more reddish coloration. the non injected tank has its own appeal with more leaves that are more compact… Had I discovered how to keep a non injected tank free from visible algae I probably would not have invested in co2 injection. Injection however does allow you to keep plants that would really struggle in a non injected tank… L. Repens responds nicely to co2 but grows quite well without it as well. 1 Link to comment Share on other sites More sharing options...
