Townsend, DE 19734 Frost Dates
Townsend, DE: when does the frost end?
The last spring frost here typically falls around 04/04, about 219 days from today. Fall's first freeze usually shows up around 11/04, roughly 214 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 Townsend, not a forecast for this year.
Stretching the season past the first frost
With roughly 10 weeks until Townsend's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/04 isn't a guarantee
04/04 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/22 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/17 and only about 1 year in 10 sees frost after that.
