Stretching the season past the first frost
Mineral Springs's growing season runs out in roughly 10 weeks — a cold frame or greenhouse kit is the usual way to keep cool-weather crops going past the first frost.
Why 03/31 isn't a guarantee
03/31 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/11 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/16 and only about 1 year in 10 sees frost after that.
