One of the best tools that you have as gardeners to help us determine 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 getting a good idea when you can plant coreopsis is to refer to the USDA zone info for Kent.

Planting Calendar for Coreopsis

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

You can plant coreopsis a bit earlier in the year because they are moderately cold tolerant.

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

Last Frost Date

Since the USDA zone info for Kent is an average the actual date of last frost will vary from year to year. Half of the time in Kent there is a last frost after March 15 so be sure to be ready to cover your coreopsis if you have a late frost.
