Stretching the season past the first frost
Cape Coral'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 01/16 isn't a guarantee
01/16 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/01 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 02/02 and only about 1 year in 10 sees frost after that.
