Greenwood, SC 29646 Frost Dates
Greenwood, SC: when does the frost end?
Typically, the last spring freeze lands around 03/26, roughly 210 days out. Fall's first freeze usually shows up around 11/12, roughly 233 days after the last spring frost.
Zone 8a (10 to 15°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 Greenwood, not a forecast for this year.
Stretching the season past the first frost
With roughly 11 weeks until Greenwood's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 03/26 isn't a guarantee
03/26 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/03 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/10 and only about 1 year in 10 sees frost after that.
