Before planting it is a good idea to find your USDA Zone info to estimate your garden 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 getting a good idea when you can plant sedum is to refer to 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.

Since sedum do well in cold you can plant them earlier in the year than plants that are more sensitive to the cold.

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

Last Frost Date

The average date of last frost is April 15 in Charleston. You can expect an average low temperature of -10°F in the coldest months of winter.

Since the USDA zone info for Charleston is not always accurate the actual date of last frost can change quite a bit from year to year. Half of the time in Charleston you get a frost after April 15 so always be ready to protect your sedum in the event of a surprise late frost.
