Stretching the season past the first frost
With roughly 18 weeks until Desert Hot Springs's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
Why 01/01 isn't a guarantee
01/01 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/18 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 12/12 and only about 1 year in 10 sees frost after that.
