One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

A way of getting a good idea when to plant broccoli is to examine the USDA zone info for Zone 12b.

Planting Calendar for Broccoli

Frost tolerance for broccoli:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Broccoli do well in moderate cold which tells us that you can start planting them earlier than other plants that might not handle the cold.

The earliest that you can plant broccoli in Zone 12b is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant broccoli and expect a good harvest is probably November. If you wait any later than that and your broccoli may not have a chance to fully mature. Starting your broccoli indoors is a great way to get them started a few weeks earlier.

Last Frost Date

In Zone 12b it never frosts. It might get as low as 55°F during the coldest months of winter.

It's important to remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 12b and it changes from year to year. Since it never frosts in Zone 12b you do not have to be ready to protect your broccoli if you have a late frost.
