Thanks for the info folks!
What about late planting of those frost tolerant items like broccoli, peas and spinach? How late can you temp fate and sneak in a late harvest risking a hard freeze? What about other fall veggies? Onions?
I planted spinach in early September one year, then covered that raised bed with clear plastic when it got really cold. I harvested spinach all throughout the winter.
Also, I planted onions from seed, in July I think, last year. They were green bunching onions. They were still small at the end of the season, so I covered them with leaves over the winter. This spring I uncovered them and they grew fast. I had green onions to eat in late April.
