When can you plant in Newbury, VT?
Around 05/15 is the usual last spring frost, about 260 days away. The first fall frost typically arrives around 09/28, about 134 frost-free days later.

Why 05/15 isn't a guarantee
05/15 is the middle of 30 years of NOAA records, not a promise. Plant by 05/03 and you're betting against frost in roughly 9 years out of 10. 05/29 is the safer bet, historically only a 1-in-10 chance of frost that late.
