FREE: 50 Pretty Pink Columbine Seeds

I found this on prechilling seeds: Refrigerate, pre-chill, or stratify:
Some seeds like columbine and penstemon germinate best after a period of cold and wet that simulates the winter season. This is called cold-moist stratification. The easiest way to stratify seeds is to sow them into their pots, water them, cover the pots with plastic, and place them in the fridge for the recommended amount of time.

If fridge space is limited, try this method: Place the seeds in a paper napkin, then fold it and moisten with tap water. It shouldn't be sopping wet, just damp. Place the napkin in a ziploc bag, and put it in the fridge. After the recommended amount of time, remove the seeds from the fridge and pot them up. This method won't work for very tiny seeds, which are difficult to handle individually. You can try stratifying these seeds in a bag with moist peat moss, which can then be scattered over the surface of the soil. The only drawback to this method is that you can't tell how thickly you're sowing the seeds.

After stratification, place the seed pots in a sunny window or under lights for germination.

how long do u pre chill seeds for?
