i grew in ct for few yrs the frost has been coming later and later each year,and from my experiance the first few frost's are not bad and my uncle has had plants out till mid november with no problem,and just cover the plant if possible and put a barraier where the ground and stalk meet to keep it covered...

but in all honesty the real bad frost doesnt come till end of nevember -december.who knows it just might be fall weather untill january.. new england weather is just never the same at all..
