Stretching the season past the first frost
With roughly 22 weeks until Temecula's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 02/02 isn't a guarantee
02/02 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/24 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/26 and only about 1 year in 10 sees frost after that.
