When can I plant Turnips in Zone 10b

It's possible to determine when it's a good idea to plant turnips by referring to the USDA zone info for Zone 10b.

Just be sure to remember that our actual date of last frost is just an average because it is based on the USDA zone info for Zone 10b and it will vary from year to year. Half of the time in Zone 10b we get a frost after January 31 so always be ready to cover your turnips if we have one of those late frosts.
