I have a lot of ferns that I haul into my house each winter from the porch. The thing is, once you have one fern you have the potential for multitudes. Think Mickey in “The Sorcerer’s Apprentice” with the brooms. All you need is an axe to chop up a root bound fern. Right now I have six, and I think at least three need to be divided next summer. In the meantime I enjoy the sight of the new fronds uncurling. The green is such a fresh color.
