I always pull the flowers off of any Eriocaulons I'm keeping. Why let the plants waste energy making flowers when you want it using energy to grow bigger and split?
Exactly. I notice that a lot of my E. parkeri flower at the same time while simultaneously stalling in general growth. I just keep pulling them off for a bit and things go back to normal. Often, this even accompanies a change in tank conditions or is a sign that they should all be split. Other species have been pretty much the same way.
I didn't pull my off on amanoanum and some how they split :p I will show you the picture of them. One grow normally one is splitting and one try to grow flower then splitting very interesting and they grow next to each other LOL, soon I will have more Amanoanum available :P
