Because germination rates are generally high, seeds are sown directly into D-40 cells containing a medium of 1.5 parts vermiculite, 1 part sterile sand, 1 part coarse turpos, and 2 parts peat moss (v:v:v:v).
Cells are watered thoroughly after sowing and are not allowed to dry out during completely during stratification.
