Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Rock Hill you can determine when it's possible to plant coreopsis by checking out the USDA zone info.

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. Starting your coreopsis indoors is a great way to get them started a few weeks earlier.
