We hope this serves a helpful general guideline for your planning and planting purposes. Beyond that it’s always best to consult the seed packet or nursery for the specific variety you’re planting.
Times to harvest can vary slightly based on the cultivar and microclimates within regions. Also, make sure to provide frost covers for protection if early frosts are expected.
Here’s an alphabetical list of herbs that can be planted in September, along with the USDA Hardiness Zones where they typically thrive:
What Herbs to Plant in September

Remember, while many of these herbs are perennials, their ability to establish and thrive when planted in the fall can be dependent on local conditions, such as the onset of winter and the severity of frost. If you’re attempting to plant perennial herbs in September, it’s a good idea to mulch them well to protect them from potential frost and give them a better chance of overwintering successfully.
