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.

In San Diego you can determine when it's possible to plant stocks by referring to the USDA zone info.

Planting Calendar for Stocks

Frost tolerance for stocks:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

You can plant stocks a bit earlier in the year because they are barely cold tolerant.

The earliest that you can plant stocks in San Diego is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant stocks and expect a good harvest is probably September. You probably don't want to wait any later than that or else your stocks may not have a chance to really do well. Starting your stocks indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

The average date of last frost is January 31 in San Diego. It might get as low as 35°F during the coldest months of winter.
