05148, near Ludlow, VT: the frost window

Zone 5a

The last spring frost here typically falls around 05/16, about 261 days from today. Fall's first freeze usually shows up around 10/02, roughly 140 days after the last spring frost.

Stretching the season past the first frost

Ludlow's growing season runs out in roughly 5 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 05/16 isn't a guarantee

05/16 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/31 and only about 1 year in 10 sees frost after that.
