pampus

I rake out the old leaves and cut off the plumes in late winter/early spring - in fact I've already done it. I also give it a feed.

If it's getting out of hand, some people cut them off (with a chainsaw!) or even burn them to the ground, and let them start again. Or - lift and split! I haven't done that but I have heard that other people have.

If it is safe and possible burning is the best. Cut back hard and rake out as Spritz says if you can't burn it.
