Collecting seeds from your plants not only serves as a source of enjoyment, but it can save you quite a bit of money each year and ensure that you grow healthy plants. Instead of buying new seeds every year, you can harvest seeds from existing plants and grow strong, healthy plants year after year.
Collect the marigold seed pods. Place a dry, clean container beneath the seed pod and then carefully break it away from the flower. Having the container beneath it will keep stray seeds from being lost. Be sure to label the container once collection is complete.
Place the seed pods in a dry place with good ventilation so that they may continue to dry out completely. Use a container that protects ponds from potential hazards such as wind, wet weather, and vermin. Dry the seeds completely, as this will reduce the potential for rotting or molding between seasons.
Shake the seed pods through a fine mesh screened sieve over a piece of clean white paper. Gently pressing the seed pods through the mesh will screen out the seed pods and chaff, while allowing the actual seeds from the marigolds to fall through onto the paper.
Store the seeds for the following season. This can be done in paper envelopes, so long as the envelopes are stored in a cool, dry place for the winter. Label each envelope properly prior to storing them.
