I am at the same stage with my spuds, (growing variety Charlotte this year)
We are not getting heavy frosts, even an overnight frost has been very light so far. I am thinking of trying a frost protection technique called 'Wall of Water'. It will be easier to look it up with a search engine than for me to try to explain on here. Have a few dozen empty 2L PEP bottles from which I could make them. It will make earlier planting an option.
Last few Winters have been very mild, but in my neck of the woods, last three years we had overnight frost on May Day.
