In one of my gardening books it says you can sow calabrese in modules under cover in Autumn, transplant in early Winter, and you should get a very early crop next year.
The packets of seeds that I have do not mention this as a planting time. Has anyone else tried this and was it successful?
depends on your location and what type of cover you use for the calabrese as it will surely rot in the frost but a double polycloche might work, you can only try but I am planning on harvesting the rest of mine over the next few weeks - good luck and please let us know how it turns out
If you're talking of big-headed ones, I would say no. And if sprouting ones, why not white sprouting? Tastes the same??
