Allium Germination:
1) Cold stratify by placing in a zip lock bag filled with moist vermiculite or peat moss and place in the fridge for 60 days. Periodically check to ensure they stay moist, but not wet.
2) Fill treys with a quality soilless medium. Wet and let drain well. 
3) Place 2 seeds in each trey cell or container, and lightly cover with 1/8" of vermiculite. Use a spray bottle to keep moist by misting.
4) Keep them at a room temperature of 72 degrees. 
5) Expect germination in 7-10 days.
