I've just spent 2 hours pruning and replanting my bacopa carolina and could not believe the amount of roots/runners that had spread through out the tank.How do people on here do it?do you just cut the stem off at substrate level or pull all the roots/runners out?They were under bog wood,through the roots of other plants,some were over 2' long.I spent an hour just removing the little roots that that were sticking out of the substrate.
