Should I give up on the cauliflower plants?
I planted cauliflower in March. I got a row of big leafy plants, still growing, but only one actually had a head of cauliflower on it. I've cooked the head and leaves and they tasted good, but I'm still hoping heads will form on the remaining plants as it gets cooler. Has that ship sailed? Should I just pull them up and plant carrots? I am near Denver, Colorado, USA (zone 5-ish). I want to plant something in a cold frame I can eat this winter but I won't bother with more cauliflower if it takes up space and doesn't produce.
