The month you plant snapdragons depends on your specific USDA hardiness zone, with planting occurring in either spring or fall.
Snapdragons (Antirrhinum majus) are versatile plants that can be planted as seedlings or transplants outdoors, depending on your climate and zone. The ideal planting times are tailored to ensure the plants establish well before extreme temperatures set in.
Optimal Planting Months for Snapdragons by Zone
Refer to the table below to determine the best months to plant snapdragon seedlings or transplants in your area:
| Zone | Planting Time (Outdoor Seedlings/Transplants) |
|---|---|
| 8a | On or around March 1 |
| 8b | On or around March 1 |
| 9a | September-November; March-April |
| 9b | September-November; March-April |
For zones 8a and 8b, early spring (March) is the prime time for planting, allowing the snapdragons to establish before the summer heat. In warmer zones like 9a and 9b, you have the flexibility of a fall planting window (September-November), which allows the plants to develop strong root systems over the cooler months, or a spring planting window (March-April). Planting in the fall in these warmer zones often leads to earlier and more robust blooms.
