Planted seeds in late April and followed instructions on packet and nothing appeared after several weeks despite me using a heat mat. I happened to read an article that said they were very difficult to germinate as the seeds are dormant you should put them in the fridge for 6 to 8 weeks to replicate winter. One article said soak the seeds before refrigeration and another article said don’t. I soaked half first and refrigerated the others without soaking. I’m still waiting for the 6 weeks to pass so don’t know if I’ll be successful. Easier to buy a jar of capers!
