Sanger, CA: when does the frost end?

Zone 9b

Stretching the season past the first frost

With roughly 15 weeks until Sanger'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

02/23 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/17 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/04 and only about 1 year in 10 sees frost after that.
