Stretching the season past the first frost

Stuart's growing season runs out in roughly 20 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.

Why 01/23 isn't a guarantee

01/23 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/04 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 02/10 and only about 1 year in 10 sees frost after that.
