Broccoli grows extremely well in cool weather. If your spring planted broccoli doesn't seem to succeed, mine hardly ever produces a good head, try growing broccoli primarily in the fall. I have had great success with broccoli I planted in late summer for fall harvest.
We leave our rutabaga in the garden until we need it. Light frosts helps instead of hurting, turning the starches into sugars and creating a sweeter tasting rutabaga.
The cold frame bed contents for greens in early winter months.
The cold frame bed consists of two different varieities of kale, arugula, romaine, mesclun mix, swiss chard, beets, green onions and rutabaga.
Kale as a cover crop.
Never underestimate the value of green onions in the garden. They take very little room, can be left in the ground all winter and used in the spring and grow super quick without being a heavy feeder.
Again.
Big ol red onions.
Celery is best stored with it's cut end 'planted' in a bucket of sand or you can simply leave it in the ground and take ribs as you please.
Swiss Chard.
Radish.
