When to do what:
Seeds can be started indoors but also directly in the soil at any time in Spring. I put out seeds late July, and they still flowered before end of season, but didn't produce many seeds. If started early, they will self-seed and produce a second generation the same year.
When flowering, harvest flowers in the morning for Calendula oil.
