Anyone know how this plant propagates? :icon_redf I have had a couple of bunches for quite some time and it doesn't spread at all. thanks
agreed 100%....on the giant form, the edges turn brown when you cut them.Giant Hairgrass spreads quickly with runners. I've found putting root tabs under them puts them in overdrive. I wouldn't recommend giving giant hairgrass a trim. I've done it with regular hairgrass and it was OK. The Giant hairgrass will get ugly brown tips if you cut it. You would be better off just completely removing long strands from the base. There are always newer strands growing like crazy so you won't have to worry about thinning it too much.
