How Cold Hardy Is Cabbage?
I planted cabbage by accident. Now I have 9 heads about 3-4 inches in diameter. We're expecting 2 hours around 30 degrees tonight and several hours down to 25 tomorrow. Can they take it or should I pick them now?

Cabbage is very cold hardy, surviving temps as low as 15-20 F. However, if you are worried about your plants or if temps fall below this, you could always add additional protection with cold frames/tunnels and mulching.
