Stretching the season past the first frost
With roughly 4 weeks until Sherwood's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 05/17 isn't a guarantee
05/17 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 05/06 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/30 and only about 1 year in 10 sees frost after that.
