What to sow when

Frost is rare in Burbank Glendale Pasadena Airport, so each crop’s months follow the warmth. Each one below can go in during these months and stay in its range of temperatures all the way to harvest. Where every month runs warmer than a crop likes, it gets the coolest months here (why).

Each crop’s range of monthly temperatures is an estimate from one extension table, so treat these months as a guide.

Where these numbers come from

NOAA NCEI 1991–2020 Climate Normals, the Burbank Glendale Pasadena Airport station (listed by NOAA as Burbank Glendale Pasadena Ap, USW00023152), at 34.20, -118.36. These are that station’s own records, unshifted. The further your garden is from it, the less exactly they describe your ground. The planner finds the nearest station to your garden and lowers its confidence with distance, so no number is presented as if it were measured in your garden.

Cold air also pools in low ground on the clear, still nights when frost happens, so a hollow can freeze while a slope a few hundred feet away does not. No table can know that about your garden. A few seasons of your own logged frosts can.
