With roughly 17 weeks until Burbank'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
12/31 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 01/15 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.
