One of the first steps you take when you are getting a good idea your gardening schedule is find your USDA Zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

You should be able to estimate when you can plant borage by referring to the USDA zone info for Zone 12a.

Planting Calendar for Borage

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

Since borage do well in moderate cold you can plant them a little bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant borage in Zone 12a 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 borage and expect a good harvest is probably November. You probably don't want to wait any later than that or else your borage may not have a chance to really do well. Starting your borage indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Zone 12a it never frosts. You should expect an average low temperature of 50°F in the coldest months of winter.

Remember that the actual date of last frost is an average because it is based on the USDA zone info for Zone 12a and it is different every year. Since it never frosts in Zone 12a you do not have to be ready to protect your borage if you have one of those late frosts.
