How much can you trim rhizome plants' holdfasts?
I've got a few anubias that have their root/holdfasts hanging out into space. I'd like to trim them to accentuate the shape of the driftwood rather than obscure it, but I don't want to hurt the plants. I have read that holdfasts don't absorb nutrients, but these ones on anubias sure look like roots. So, how much can you cut?
