Burbank gardening questions

When is the last frost in Burbank, CA?

Plan around Jan 10. At NOAA's Burbank Valley Pump Plt, CA station, 1.2 mi from the city center, there is a 30% chance of a 32°F frost after that date. Half of springs have their last frost by Jan 2, and after Jan 31 the risk drops to about 1 in 10. Springs here are erratic: 51 days separate the 90% and 10% dates, versus a median of 36 days for cities on this site, so watch the forecast rather than the calendar.

When should I plant tomatoes in Burbank, CA?

Start seeds indoors Nov 15 – Nov 29 and set transplants outside Jan 17 – Jan 31, once nights stay above 50°F and the soil is near 60°F. With about 340 frost-free days, frost is not the main limit — fruit set drops when nights stay above about 75°F, so early plantings tend to do best. More: tomato planting dates by zone.

How long is the growing season in Burbank?

About 364 days without a 32°F frost in a typical (median) year. In 9 years out of 10 the season lasts at least 330 days, and in 1 year in 10 it runs 365 days or more. In fall there is a 10% chance of frost by Dec 5 and a 30% chance by Dec 16. That ranks 26th longest of 84 California cities on this site.

When should I plant a fall garden in Burbank?

Count back from the first fall frost (Dec 16): transplant broccoli Sep 23 – Oct 7; sow kale Oct 7 – Nov 4; sow lettuce Oct 7 – Nov 4; sow radishes Nov 4 – Dec 2. How the math works: succession and fall planting.

Did Burbank's hardiness zone change on the 2023 map?

No. Going by the zone that covers most of the city's land, Burbank is zone 10a on both the 2012 and the 2023 USDA maps (PRISM/OSU ZIP listings). About 42% of U.S. ZIP codes kept their half-zone in 2023. Why the 2023 map is warmer.

How does Burbank compare with Glendale, CA?

Both are in zone 10a. The typical last spring frost in Burbank (Jan 10) comes about 4 days earlier than in Glendale, CA (Jan 14), 5 miles away, and the first fall frost is Dec 16 versus Jan 1. Burbank sits about 725 ft lower, which explains part of the gap. The two cities use different NOAA stations.
