Calendula Growing Information:

How to grow Calendula:

To propagate Calendula by seed - Sow Calendula seeds outdoors during spring, or start them indoors 6 to 8 weeks before the last frost. Avoid warm temperatures, as they will produce only weak plants. Keep the calendula seeds covered with soil, as the light inhibits germination. For optimal fall flowering start the new set of seedlings during summer. Note that the Calendula seeds self-sow readily. The plant needs germination temperature from 55 F to 60 F.
