Manchester, VT 05250 Frost Dates

When can you plant in Manchester, VT?

Zone 5a

Typically, the last spring freeze lands around 05/13, roughly 258 days out. The first fall frost typically arrives around 09/29, about 137 frost-free days later.

The USDA Plant Hardiness Zone Map puts Manchester in Zone 5a (-20 to -15°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.

What to do before the first frost

About 5 weeks of growing season left in Manchester before the first fall frost — a cold frame or row cover can stretch harvest weeks past that date.

Why 05/13 isn't a guarantee

05/13 is the middle of 30 years of NOAA records, not a promise. Plant by 04/30 and you're betting against frost in roughly 9 years out of 10. 05/28 is the safer bet, historically only a 1-in-10 chance of frost that late.
