Mordecai13 Posted June 27 Share Posted June 27 (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 June 28 Share Posted June 28 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 June 28 Share Posted June 28 (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 June 29 by Pepere 1 1 Link to comment Share on other sites More sharing options...
Pepere Posted July 1 Share Posted July 1 @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...
