Plant City, FL 33527 Frost Dates
Plant City, FL: when does the frost end?
Around 01/20 is the usual last spring frost, about 145 days away. Fall's first freeze usually shows up around 01/12, roughly 365 days after the last spring frost.
Zone 9b (25 to 30°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 Plant City, not a forecast for this year.
Stretching the season past the first frost
With roughly 20 weeks until Plant City's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 01/20 isn't a guarantee
01/20 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/10 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/27 and only about 1 year in 10 sees frost after that.
