When should I plant calendula seeds, in the spring or the fall?
Calendula, known as Pot Marigold, English Marigold, Poet’s Marigold or by its latin name, Calendula officinalis is a great addition to any garden and the seeds self sow readily. Some would say too readily so be careful of where you place them if you want a controlled planting.
The University of Cornell tells us to: “Sow seeds outdoors a few weeks before the last frost in the spring, or start them indoors 6 to 8 weeks before the last frost. Avoid warm propagation temperatures, as they will produce weak plants. Keep the seeds covered with soil, as light inhibits germination. Start an additional set of seedlings in the summer for optimal fall flowering. Calendula’s vivid orange or yellow flowers provide not only a splash of color to the garden, but add zest to salads and similar dishes as well. Calendula is exceptionally tolerant of cold weather in fall, and has long been grown as a pot herb for its edible flowers.
