When can you plant in Glendale, CA?
The last spring frost here typically falls around 01/08, about 133 days from today. The first fall frost typically arrives around 01/07, about 365 frost-free days later.
The USDA Plant Hardiness Zone Map puts Glendale in Zone 10a (30 to 35°F average annual minimum); frost dates are NOAA's 1991-2020 station normal, not this year's forecast.
What to do before the first frost

Why 01/08 isn't a guarantee
01/08 is the middle of 30 years of NOAA records, not a promise. Plant by 02/17 and you're betting against frost in roughly 9 years out of 10. 12/20 is the safer bet, historically only a 1-in-10 chance of frost that late.
