Barclay, MD: when does the frost end?

Stretching the season past the first frost
With roughly 10 weeks until Barclay's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
04/03 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 03/20 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.
