Stratification of seeds is the process of exposing seeds to cold conditions in order to encourage germination.
The exact process you choose (there are two options) depends on the flower variety you’re growing. Let us explain!
There are two ways to cold stratify seeds.
Plant them in the fall, let them go through a winter, and they will sprout the next year.
Create a false winter by chilling them in a plastic bag with dampened peat, paper towels, or sand in the refrigerator.
This method varies by seed, so check the planting guide. For cold moist stratification, dampen the seeds and place them in the bag.
Check for mold and fungus and plant them right away if present.
