Stretching the season past the first frost
Arlington'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.
Why 03/09 isn't a guarantee
03/09 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 03/28 and only about 1 year in 10 sees frost after that.
