First frost countdown

Zone 10 is frost-free in a typical year. Nothing here is racing a freeze — heat and rainfall set the calendar instead.

Common questions

When is the first frost in Zone 10?
Zone 10 is frost-free in a typical year, so there is no first-frost date to plan around. Heat and rainfall drive the growing calendar here instead.
Which vegetables actually taste better after a frost?
Kale, Brussels sprouts, parsnips, carrots, leeks and cabbage all sweeten after a frost, because cold converts their stored starches into sugars.
