Oh okay will leave it longer then!Hi, I wouldn't trim mini hairgrass for now, it still needs to spreads and get better color, it doesn't like trimming, looks Bad when trimmed and sometimes hard to recover. Just wait until the carpet is full.
Stems looks OK to me
The stems look fine to me too, however I just think they're growing very slowly for stems ...
Especially compared to the other rotala I have, green + orange juice.
