Pre-treatment: Seeds are naturally stratified outdoors during fall months. Seeds are directly sown (3-5 per cell) into D40 cells containing a medium of 1.5 parts vermiculite, 1 part sterile sand, 1 part coarse turface, and 2 parts peat moss. Cells are watered thoroughly after sowing and are not allowed to dry out completely during stratification and germination.
