I have several different types of ferns which are finally bulked up enough to try to figure out what to actually do with them. Last year I experimented with cutting old fronds right back to the ground as the new ones unfurled on my native swords and that seemed to work well. I'm now wondering if I can do the same with all the rest of the ferns, or if this rather drastic action might set back some. Any ideas? They sure look better to get rid of all the ratty stuff from the winter. I have deer fern, maidenhair fern, autumn fern, and some others. Also, is spring or fall a better time to divide them? Thanks.
