Which root veg can overwinter?
I have leeks, salsify, root parsley and parsnip which can be left in the ground until required. However, I also have some carrots and beetroot some of which was planted in August from modules, hence small. How long can the carrots and beetroot stay in the ground? Are they at all frost tolerant? If not, when will I have to harvest them for storage?
Oh yes, and my salsify leaves are looking wilted. Is this usual? I don't think it is, but I'm not sure. Those I have harvested have been modest sized, or badly forked and not really useable possibly due to the stony soil, although parsnip has done okay, so maybe the compost was too rich.
