Stretching the season past the first frost
Columbus'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 03/27 isn't a guarantee
03/27 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/09 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/14 and only about 1 year in 10 sees frost after that.
