Introduction
Nasturtiums are not only eye-catching additions to any garden, but they also have a variety of uses that make them a favorite among gardeners. From bright colors to edible leaves and flowers, nasturtiums offer more than just aesthetics. One of the best parts about growing nasturtiums is how easy it is to propagate them from seeds, making them a sustainable choice for both beginner and experienced gardeners. This article will guide you through the steps to harvest nasturtium seeds and provide helpful tips to ensure a bountiful and beautiful garden season after season.
What Are Nasturtiums and Why Harvest Their Seeds?
Nasturtiums (Tropaeolum) are easy-to-grow annual flowers known for their vibrant colors, edible blooms, and ability to attract beneficial insects to your garden. They thrive in poor soil, making them perfect for low-maintenance gardening. Additionally, harvesting their seeds allows you to save money, maintain a sustainable garden, and share the joy of nasturtiums with friends and family.
Benefits of Harvesting Nasturtium Seeds
- Cost-Effective: Save money by growing nasturtiums from harvested seeds instead of buying new ones each season.
- Sustainability: Seed saving reduces waste and promotes a more sustainable gardening practice.
- Sharing: Share harvested seeds with friends, family, or local seed swaps.
- Plant Diversity: Encourage genetic diversity by planting seeds from your garden rather than relying solely on commercial seeds.
Now, let’s dive into the step-by-step process of harvesting, storing, and planting nasturtium seeds!
Step 1: Recognize the Seed Pods
After the flowers of your nasturtium plants fade, they start to form round seed pods at the base of the flower. These pods will initially be green, signaling that they are still developing. The seeds inside mature over time and gradually change color. Keep an eye out for pods that are swollen and beginning to turn from green to a beige or light brown color. This is your indicator that the seeds are mature and almost ready for harvesting.
Tips:
- Avoid picking the pods when they are still green; immature seeds may not germinate as effectively.
- Check the plant regularly for mature pods, as they can drop off once they are fully ripe.
Step 2: Collect the Seeds
The best time to collect nasturtium seeds is when they are fully mature and about to drop from the plant. Mature seeds should be firm to the touch and dry. Gently pick the seed pods off the plant using your fingers; they should come off easily without resistance.
Tips:
- It’s best to collect seeds in the morning after the dew has evaporated to ensure they are dry.
- Use a small container or paper bag to carry the seeds without losing any.
Step 3: Air Dry the Seeds
Once you have collected the seeds, it’s crucial to dry them thoroughly before storage. Place the harvested seed pods on a paper towel or a piece of newspaper in a cool, dry location with good air circulation. Allow them to air dry for about a week or until they are completely free of moisture.
Tips:
- Avoid drying seeds in direct sunlight, as it can damage them.
- Check on the seeds daily, and gently shake them to ensure they are drying evenly.
Step 4: Clean and Prepare for Storage
After drying, separate the seeds from any remaining pod material. You may notice that the seeds have a wrinkled, slightly bumpy appearance. This is normal and indicates they are fully mature. Brush off any debris or chaff before preparing them for storage.
Tips:
- Handle the seeds gently to avoid damaging them.
- Remove any seeds that appear moldy or damaged.
Step 5: Store the Seeds Properly
Proper storage is key to ensuring that your nasturtium seeds remain viable until the next planting season. Place the clean, dry seeds in a paper envelope, small cloth bag, or glass jar with a secure lid. Label the container with the date and type of seeds. Store them in a cool, dark, and dry location, such as a pantry, basement, or refrigerator. The goal is to keep them away from heat, humidity, and direct sunlight.
Tips:
- Use a silica gel packet or dry rice to absorb any excess moisture in the container.
- Seeds stored properly can last for several years.
Step 6: Test Seed Viability
Before planting your harvested seeds, it’s a good idea to test their viability. Take a few seeds and try germinating them indoors using the paper towel method. If they sprout successfully, your seeds are ready for the garden!
Tips:
- Consider testing in early spring to ensure you have time to buy fresh seeds if necessary.
- Sow viable seeds directly into the soil or in starter pots indoors.
Step 7: Planting Your Harvested Seeds
When it’s time to plant your nasturtium seeds, choose a sunny location with well-draining soil. Nasturtiums thrive in poor soil, so there’s no need to fertilize heavily. Simply plant the seeds about 1/2 inch deep and 10-12 inches apart. Water them gently to settle the soil.
Tips:
- Nasturtiums grow quickly, so there’s no need to start them indoors unless you want an early start.
- Keep the soil consistently moist but not soggy until the seedlings emerge.
Additional Tips for Growing and Caring for Nasturtiums
- Watering: Water regularly, but avoid overwatering. Nasturtiums are drought-tolerant and prefer slightly dry soil.
- Pests: Keep an eye out for aphids and caterpillars. Use natural pest control methods like neem oil or soapy water if necessary.
- Companion Planting: Nasturtiums are excellent companion plants. They repel pests like aphids and beetles and attract beneficial insects like pollinators. Consider planting them alongside tomatoes, cucumbers, or beans.
Common Problems and How to Solve Them
- Leggy Growth: If your nasturtiums become leggy, it usually means they are not getting enough sunlight. Ensure they receive full sun for best growth.
- Yellow Leaves: Yellowing leaves may indicate overwatering. Adjust your watering schedule and ensure the soil drains well.
- Poor Flowering: If your nasturtiums are not blooming well, it may be due to too much fertilizer. These plants prefer nutrient-poor soil.
