Nasturtiums are beautiful, easy-to-grow flowers that can add vibrant color to your garden. One of their best features is that you can save their seeds to plant again next year, saving money and ensuring you have your favorite varieties year after year.
Why Save Nasturtium Seeds?
Saving seeds from your nasturtiums allows you to propagate plants that are well-suited to your garden conditions. It also helps preserve unique varieties and reduces the need to buy new seeds each season. Plus, it’s an easy process that anyone can do.
When to Harvest Nasturtium Seeds
The best time to harvest nasturtium seeds is after the flowers have faded and seed pods have matured. Look for seed pods that are dry, brown, and firm. Usually, this occurs in late summer or early fall, depending on your climate.
Steps to Harvest Seeds
- Wait until seed pods are fully mature and dry.
- Carefully cut the seed pods from the plant using scissors or garden shears.
- Place the seed pods in a paper bag or a dry container.
- Allow the pods to dry further in a cool, dry place for a few days.
- Once fully dry, gently crush the pods to release the seeds.
- Separate the seeds from the chaff by winnowing or using a sieve.
Storing Nasturtium Seeds
Store your seeds in a labeled, airtight container in a cool, dark place. Proper storage can keep seeds viable for 2-3 years. Make sure to keep the seeds dry to prevent mold and decay.
Tips for Successful Seed Saving
- Choose healthy, disease-free plants for seed collection.
- Label your seeds with the variety and date of harvest.
- Keep seeds dry and avoid exposure to direct sunlight.
- Test seed viability by placing a few seeds in water; viable seeds sink.
- Start the seeds indoors early or sow directly in the garden after the last frost.
By following these simple steps, you can enjoy a continuous supply of beautiful nasturtiums in your garden while saving money and preserving your favorite varieties for years to come.
