Nasturtiums are vibrant, easy-to-grow plants that add color and flavor to your garden. Saving their seeds for next season is a simple way to ensure you have a continuous supply of these beautiful flowers and edible leaves. Here’s a step-by-step guide to help you harvest and store nasturtium seeds properly.
When to Harvest Nasturtium Seeds
The best time to collect nasturtium seeds is after the flowers have faded and seed pods have matured. Usually, this occurs in late summer or early fall. Look for seed pods that are fully developed, firm, and starting to turn brown or tan. Avoid collecting seeds too early, as they may not be fully mature, leading to poor germination.
How to Harvest Seeds
Follow these steps to harvest nasturtium seeds:
- Gently pick the seed pods from the plant, using scissors or your fingers.
- Place the seed pods in a paper bag or a breathable container.
- Allow the pods to dry in a warm, dry place for about a week.
- Once fully dried, carefully crack open the pods to extract the seeds.
How to Store Nasturtium Seeds
Proper storage is essential to keep seeds viable for next year. Here are some tips:
- Place the seeds in an airtight container, such as a small jar or a sealed plastic bag.
- Label the container with the date and variety.
- Store the seeds in a cool, dark, and dry location, like a pantry or a drawer.
- Check the seeds periodically to ensure they remain dry and undamaged.
Tips for Successful Germination
When planting your saved nasturtium seeds next season, keep these tips in mind:
- Soak the seeds in water overnight to improve germination.
- Plant the seeds about 1/2 inch deep in well-draining soil.
- Ensure they receive full sun for optimal growth.
- Water regularly, keeping the soil moist but not waterlogged.
By following these simple steps, you can enjoy a thriving nasturtium garden year after year, saving money and cultivating your favorite plants with ease.
