One of the first steps you take when you are making a decision about your gardening schedule is find your 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.

It's a good idea to figure out when it's the best time to plant sedum by using the USDA zone info for Charleston.

Planting Calendar for Sedum

Frost tolerance for sedum:	Very tolerant of frost.
When to plant:	Up to 7 weeks before last frost.

Sedum do well in cold weather which means that you can plant them much earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant sedum 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 sedum and expect a good harvest is probably October. Any later than that and your sedum may not have a chance to fully mature. Starting your sedum indoors is a great way to get them started a few weeks earlier.
