New growth on top, dead lower leaves.
I have Rotala indica and Ludwiga repens planted fairly heavily in my tank. Well it was heavily planted until all the lower leaves and stems died and rotted. So, my question is how do I prevent this from happening? Now I'm trying to keep each stem seperated so everything gets light below the top growth but I dont like the look. The tank looks thinned out now. How do I keep the lower growth alive with all the new growth coming in on top? Any pruning techniques I should try? I'm going to try and trim each stem so there is only the main stem with no periferal stems coming off to block the light. Would that work? Or is there just a point you have to hack all the good growth off the top and rip all the dead stuff out and replant again? Thank you for any suggestions.
