Before planting it is a good idea to find your USDA Zone info to determine 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.

A way of figuring out when to plant carnation is to use the USDA zone info for Zone 12a.

Planting Calendar for Carnation

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

Carnation tend to make it in a bit of cold which means that you can plant them earlier in the year than other frost tender plants.

The earliest that you can plant carnation in Zone 12a 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 carnation and expect a good harvest is probably November. If you wait any later than that and your carnation may not have a chance to really do well. If you are starting your carnation indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

In Zone 12a it never frosts. In the coldest months of winter you can expect an average low temperature of 50°F.

Since the USDA zone info for Zone 12a is an average the actual date of last frost is different every year. Since it never frosts in Zone 12a you do not have to be ready to protect your carnation in the event of a late frost.
