Stretching the season past the first frost

Cooper's growing season runs out in roughly 11 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 03/18 isn't a guarantee

03/18 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/01 and only about 1 year in 10 sees frost after that.
