Wild ginger can be propagated most easily through division of its rhizomes in early spring, but also through seed, though seed propagation requires patience and specific conditions. 

Here’s a more detailed guide:

1. Division (Rhizomes):

  • Timing: Early spring, as new growth emerges.

Method:

  • Carefully remove some soil around the plant to expose the rhizomes (underground stems). 
  • Use a sharp knife or shovel to cut sections of rhizome, each containing a pair of leaves, into 2-3 inch pieces. 
  • Plant the sections in prepared soil, ensuring the soil line on the new growth is the same as before the division. 

Note: Wild ginger rhizomes grow close to the surface, making division relatively easy.
