One of the best tools that you have as a gardener to help figure out your gardening schedule is the USDA zone info. The zone information's most crucial data reveals the average last frost and the lowest expected temperature for your area.
To determine the appropriate planting time for carnations, you can utilize the USDA zone information for the 8a region.
Planting Calendar for Carnations
| Frost tolerance for carnations | Tolerant of some frost |
| When to plant | Up to 5 weeks before last frost |
Because carnations are slightly tolerant to cold, you can plant them earlier in the year compared to other frost-sensitive plants.

Watch the weather forecast before planting outside, and have frost protection ready if low temperatures are expected.
