Large clumps of Psilotum can easily be divided, but it often seems to do
better when crowded (over-divided and overpotted plants sometimes grow ok
but stop sporing for a long time). Small pieces from a clump taken along
with their rhizomes are very hard to establish. Spores can be grown, but
are very slow; I saw a recipe by Bierhorst that basically involved sowing
the spores into old soil in a pot of Amaryllis or other plant (The mycotrophic
gametophytes and rhizomes of Psilotum survive well in crowded pots of other
plants, and often one sees many volunteers in greenhouses).
