Marigold seeds remind me of small paint brushes and pulling them out of their dry pods is as much fun as growing the edible flower.

The best time to harvest marigold seeds is when the petals have shrivelled and fallen off the flower and the seed pod has turned brown and dry.

  • Snip off the dried flower head from the stem and discard dried petals if there are any left.
  • To retrieve the seeds, gently pull them out from the pod and leave them to dry on a paper towel for about a week.
  • Place the seeds in a plain paper envelope, label it with the name of the plant and the date harvested.
  • Store the envelope in a cool, dry place.

Each marigold flower produces many seeds so once you have collected them, you don’t have to buy marigold seeds again.
