One of the best tools that you have as gardeners to help us estimate 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 estimating when it's possible to plant tagetes is to look at the USDA zone info for San Fernando.

The last month that you can plant tagetes and expect a good harvest is probably September. You probably don't want to wait any later than that or else your tagetes may not have a chance to fully mature. You can get started a little bit earlier by starting your tagetes indoors.
