My broccoli are still somehow alive!!! They've all got small heads growing, some of which actually set after the first frost! I'm keeping them going by watering early in the morning on sunny days with warm water so that it can be absorbed before it freezes and offsets hard frost from setting into the soil. If I had known how long these little guys would survive I would have either built a coldframe / mini greenhouse or mulched / insulated around the raised beds. I water from my walkout rooftop using the sink / hose setup that I created in the summer!
