Thompson's Station, TN: when does the frost end?

Zone 7b

The last spring frost here typically falls around 04/03, about 218 days from today. Fall's first freeze usually shows up around 11/01, roughly 211 days after the last spring frost.

Zone 7b (5 to 10°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Thompson's Station, not a forecast for this year.

Stretching the season past the first frost

With roughly 9 weeks until Thompson's Station's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.

Why 04/03 isn't a guarantee

04/03 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/17 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/22 and only about 1 year in 10 sees frost after that.
