One of the best tools that you have as gardeners to help us figure out 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 making a decision about when you can plant tagetes is to use the USDA zone info for Carson.

Since tagetes are not cold tolerant you need to wait until after the last frost when the weather gets warmer before you can plant them.

The earliest that you can plant tagetes in Carson 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 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 really do well. If you are starting your tagetes indoors then you might be able to get away with starting them a couple of weeks earlier.
