Nasturtiums are beautiful, easy-to-grow plants that add vibrant color to gardens. Harvesting their seeds allows you to grow new plants year after year. Here’s a simple guide on how to collect nasturtium seeds for future planting.
When to Harvest Nasturtium Seeds
The best time to harvest nasturtium seeds is after the flowers have faded and seed pods have matured. Typically, seed pods turn brown and start to dry out, indicating they are ready for collection. This usually occurs in late summer or early fall, depending on your climate.
How to Collect Nasturtium Seeds
- Wait until seed pods are dry and brown.
- Carefully cut the seed pods from the plant using scissors or pruning shears.
- Place the seed pods in a paper bag or a breathable container.
- Allow the pods to dry further in a cool, dry place if needed.
- Once fully dried, gently crack open the pods to release the seeds.
Storing Nasturtium Seeds
Store the seeds in a labeled paper envelope or a small airtight container. Keep them in a cool, dark, and dry location. Proper storage can keep nasturtium seeds viable for up to 3-4 years, ensuring you have healthy seeds for future planting seasons.
Tips for Successful Planting
- Plant seeds in well-drained soil with plenty of sunlight.
- Sow seeds about 1/2 inch deep in the soil.
- Water regularly but avoid overwatering.
- Thin seedlings to give each plant enough space to grow.
By following these simple steps, you can enjoy a continuous supply of colorful nasturtiums in your garden year after year. Happy harvesting!
