One of the first steps you take when you are figuring out 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.

One way of getting a good idea when to plant tagetes is to use the USDA zone info for Eureka.

When to plant:	After all chance of frost has passed.

Since tagetes are not cold tolerant it's important to wait until after the last frost has passed before you can plant them.

The last month that you can plant tagetes and expect a good harvest is probably September. Any later than that and your tagetes may not have a chance to really do well. You can get started a little bit earlier by starting your tagetes indoors.
