75025, near Plano, TX: the frost window

Zone 8b

The last spring frost here typically falls around 03/07, about 191 days from today. Fall's first freeze usually shows up around 11/21, roughly 259 days after the last spring frost.

Stretching the season past the first frost

Plano's growing season runs out in roughly 12 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

How much risk comes with planting early here

03/07 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/18 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 03/29 and only about 1 year in 10 sees frost after that.
