What is stratification?
We have found that some seeds germinate better after a period of combined moisture and cold. We therefore indicate recommended stratification in the description. This information, necessary for adequate germination, will also be included on your packet.
How to stratify your seeds?
This involves sowing at least a month in advance and placing the moistened tray in a plastic bag in the refrigerator or outside. Still have questions?
