How to winter sow

Most native plants need their seeds to go through a process to cool and warm the seeds so that their outer shell softens, enabling them to sprout (also called cold moist stratification or CMS). This cycle is naturally provided by our winter and spring seasons. 

Plants that require stratification cannot simply be sown directly outdoors either in the soil or in pots in the spring.

Quick step-by-step videos are available on our YouTube channel (How to winter sow playlist).

The Master Gardeners of Northern Virginia also has a Guide for Youth on Winter Sowing.

You can also print winter sowing instructions by scrolling at the end of this page.

Plants that do not require cold moist stratification are listed on the Prairie Moon Nursery website.
