I have a very new aquarium and planted two specimen of Echinodorus Tenellus in the fresh dirt/gravel substrate. I bought the plants without paying too much attention to the stems they were developing but now I'm beginning to get a little worried about them. My main goal is to get the plant to propagate in order to get a nice bed of grass, and from what I read Echinodorus is supposed to generate runners. However, I don't see any runners yet. What I do see is the stems on both of the plants growing like crazy and developing a large number of buds.
So my question is, should I just let the plants grow flowers or would it be better to cut the stems, hopefully letting the plant create runners instead?
Attached is a picture of the plants. As you can see there's one runner already there but that was already there when I bought it and it's not doing very well I think.
