Marigold flowers and seeds

Wide varieties of Marigolds are self-seeding. Upon maturity, their flowers containing seeds will drop to the ground and spread throughout the flowerbed.

If you want to stop it from multiplying, deadheading is a popular technique gardeners use to encourage a second bloom, maintain the plant's appearance, and prevent further regrowing.

Most common varieties of marigolds are annuals, but because they reseed, others tend to mistake them as perennials as they keep regrowing every season.

Marigold seeds germinate quickly and are easy to sow. It's easy to save the seeds if you want to keep some for the next replanting. Take a mature bloom, shake out the seeds, and air dry.
