How To Harvest Nasturtium Seeds
You can save Nasturtium Seeds by plucking them from the plant, the seeds are in the center of the now wilted or absent flowers. The light green wrinkled seeds are usually in clusters of 2, 3 or 4. *Only pick Nasturtium seeds from the plant if they fall away easily, if they are reluctant to move, or you have to pull or tug, leave them on the plant a little longer…they are not ready.
You can also collect them from the ground, Nasturtium seeds disperse readily at the end of the growing season. Scattering lots of tiny wrinkled seeds all over the undergrowth. Nasturtium seeds can be harvested while still Green, as long as they have a lovely plump appearance they are fine.
How To Dry Nasturtium seeds
You may find some of the Nasturtium seeds you picked are already dry and have a brown shrivelled appearance. For those that are still green, you need to dry them out thoroughly before storing. To Dry Nasturtium Seeds, spread them out on Paper or Newspaper, place in a dark, dry environment and allow them to dry out and turn brown…this should take around 1-2 weeks.
How to Store Nasturtium Seeds
Once the seeds are completely dry, store them in a glass Jar or Envelope paper envelope. Please don’t store them in a plastic bag, this can invite inadequate air circulation and encourage mould to form. Keep in a coo, dark environment for sowing in the Spring.
