One way of estimating when it's the best time to plant coreopsis is to consult the USDA zone info for Encinitas.

Planting Calendar for Coreopsis

Frost tolerance for coreopsis:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Coreopsis do well in a little bit of cold which means that you can plant them a little bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant coreopsis in Encinitas is January. However, you really should wait until February if you don't want to take any chances.

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