When to Harvest Calendula Seeds

When harvesting calendula seeds, timing is essential. Calendula typically matures in late summer or early autumn and the flowers should be allowed to mature and form seed heads before being harvested. When ready for harvest, the seed heads should be a brownish-orange color.

Harvest Calendula Seeds

Seeds should be collected after they are almost fully ripe. To prevent self-seeding, a small gauze bag should be put on the wilted inflorescences, while fixing it on the stem. This will prevent the seeds from scattering when collecting. It is best to harvest on a dry and sunny day for optimal results.

If you choose to harvest later, wait until the seed heads turn brown and then cut off whole stalks with scissors. Once harvested, place them on newspaper or paper towels and allow them to air-dry at room temperature.

Seed Preparation for Storage

Once the seed heads are dry, it is time to separate the seeds from the chaff. The best way to do this is with a small brush and a flat tray. Gently rub the seed head on top of the paper towel or newspaper until all the seeds have been removed. After the seeds are separated, make sure to remove any debris, such as sticks or leaves.
