It's funny. I just bought skirret seeds from
https://akene.ca/products/semences-chervis?_pos=1&_sid=60b9d3aa5&_ss=r
(the order is on its way). However, I did not realize that the seeds need to be stratified first. According to their directions it says:
"Growing Notes | Seeds - Skirret
Sowing and Growing
Skirret seeds are slow to germinate and should ideally be soaked in fresh water for 24 hours, then cold stratified for 45 to 60 days in the fridge.
To stratify, mix one part seeds with three parts moist vermiculite, then place the mixture in an airtight bag in the fridge for 45 to 60 days.
After stratification, you can sow the seeds in pots indoors in March. Transplant your seedlings into the garden once the risk of frost has passed, spacing them 45 cm apart.
Using deciduous wood mulch, ramial chipped wood, or leaves will help keep the soil cool and moist while preventing weeds from competing with the plant.
Skirret will appreciate a cool, deep soil, and it is even suited to wetter soils that are often avoided by other vegetables".
So...If I follow directions, it will be Fall in my neck of the woods. The packet contains 100 seeds, so maybe, I'll just try few and see what happens, or wait until next year.
