Marigolds are common and inexpensive garden annuals, but that doesn't mean you can't, or shouldn't, collect seeds from your Marigold flowers for next year. This year was the first year in a really long time that I grew Marigolds in my garden. I grew them alongside a few vegetables and herbs as companion plantings. Over the weekend I found myself doing some cleaning in the garden and a took a few minutes to save a few seeds from my potted Marigolds for next year. Marigolds don't produce large or round seeds- which can make figuring out where the Marigold seeds are confusing for the beginner gardener or first time seed saver.
One of the last few Marigold blooms in my garden, past its prime but not yet ready to give up any seeds. How to Collect Marigold Flower Seeds.
Marigolds don't produce seed pods that make it easy to identify where the seeds are and the uninitiated gardener/seed saver may wonder if the seeds have fallen out and been lost. The seeds here are a long ways from being ready for harvesting.
I generally wait until the flower heads look brown and dried like the two Marigold heads in this picture. When they look like these two, the seeds are ready to be collected and saved for next year.
To remove the seeds of the Marigold pinch the ends with your thumb and index finger of each hand, then pull apart and the seeds will slide out without any problem.
The Marigold seeds are on the left, they are long slender, black and the points of the seeds are very sharp. You can sow the seed directly where you'd like for them to grow next year in the garden or you can bring them indoors and dry them before storing them.
Here's a garden video I made showing how to collect marigold seeds from the plants in your garden.
