The USDA Zone info is a great tool for gardeners to help us figure out your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of figuring out when to plant lunaria is to check out the USDA zone info for Charleston.

Planting Calendar for Lunaria

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

Since lunaria are one of those plants that can tolerate a little bit of cold weather you can plant them a bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant lunaria in Charleston 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 lunaria and expect a good harvest is probably October. If you wait any later than that and your lunaria may not have a chance to really do well. You can get started a few weeks earlier by starting your lunaria indoors.

Last Frost Date
