Very poor germination
Review by Sue S. on 21 Jul 2022review stating Very poor germination
I tried to start these seeds using the winter sowing method. I started them in mid-March and only 4 seeds germinated. That said, it was a bad year for winter sowing. Too cloudy and too cold for too long, I suspect. All my seeds did poorly.
