How to Store the Seeds From a Nasturtium Plant
- 1). Heat the oven to 100 degrees Fahrenheit.
- 2). Place the seeds on a cookie sheet in a single layer. Put the sheet in the oven and leave the door ajar. Dry the seeds for six hours.
- 3). Transfer the seeds to a container you can seal to keep moisture out. If you immerse it in water, the liquid shouldn't seep in. Place the seed jar in the freezer or refrigerator. The seeds will keep for 10 years or more.
