One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of estimating when to plant sedum is to consult the USDA zone info for Corona.

Planting Calendar for Sedum

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

Sedum tend to make it in a bit of cold which tells us that you can plant them a lot earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant sedum in Corona 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. You probably don't want to wait any later than that or else your sedum may not have a chance to grow to maturity. If you are starting your sedum indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

The average date of last frost is February 15 in Corona. It might get as low as 25°F during the coldest months of winter.

It's important to remember that USDA zone info for Corona is an average and the actual date of last frost will vary from year to year. Half of the time in Corona you get a frost after February 15 so always be ready to cover your sedum in the event of one of those late frosts.
