I really like to promote 4-season vegetable gardening here in the Carolinas.
There's no reason not to grow winter-hardy vegetables (kale, collards, and the like) through the winter, if you like greens. The last two winters, though, have not been kind to even normally hardy (without any protection) winter vegetables.
So I've started from "scratch" two years in a row now. Hmm...
I do have a decent patch of creasy greens in the Piedmont (it can freeze solid and bounce back) along with a similar, but less robust patch in the mountains. The mache is coming back in one of my flats, too. It's a tough plant.
The perennial leeks, although frosted, are fine, too. And the chives are emerging, woo-hoo!
I'm cleaning up the main vegetable garden beds here in the Piedmont, readying them to plant. I won't be planting them, simply keeping them ready for the next gardener who will come.
This image of the main vegetable garden and shed is one of my favorites - our real estate agent loved it. The garden shed has been cleaned up. It's ready for the next gardener, too.
