I don't winter sow until after this cold has passed. I doubt much would survive this.
Here is a link that might be useful: my website
Brrrrrrrr hardly begins to cover it! I'm holding on to the consolation that all my plants are safe under 15+ inches of snow, instead of totally exposed to the dry cold this year. It was -12 this morning down by the Susquehanna in Endwell, so I KNOW it was colder up in the hills.
Stay warm, and dream and plan for the gardens of spring!
ooooohhhhh! I thought it was bad here at -5 at 4;00a.m.
spring can't come soon enough for me. My winter sown containers that I have done so far are all snuggled in the snow too.
In Jefferson County (about 60 miles north of Syracuse) it was -24 degrees this a.m. That's nasty!
