One of the best tools that you have as gardeners to help us figure out your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

A way of estimating when to plant stocks is to refer to the USDA zone info for Sierra Madre.

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.

Stocks are barely cold tolerant which means that you can start planting them slightly earlier than other frost tender plants.

The earliest that you can plant stocks in Sierra Madre 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 grow to maturity. You can get started a little bit earlier by starting your stocks indoors.

Last Frost Date

In Sierra Madre the average date of last frost happens on January 31. You should expect an average low temperature of 30°F in the coldest months of winter.

Keep in mind that USDA zone info for Sierra Madre is not always accurate and the actual date of last frost will vary from year to year. Half of the time in Sierra Madre there is a last frost after January 31 so be sure to be ready to protect your stocks if you have a surprise late frost.
