Stretching the season past the first frost
With roughly 7 weeks until West St. Paul's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 04/24 isn't a guarantee
04/24 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 04/09 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 05/10 and only about 1 year in 10 sees frost after that.
