What To Know
- The ideal time to harvest oxalis seeds is when the seed pods have fully matured and turned brown or have begun to split open.
- Spread the harvested seed pods on a piece of paper or a tray in a dry, well-ventilated area.
- You can gently rub the pods between your fingers to extract the seeds, or you can place the pods in a paper bag and shake them vigorously.
Oxalis, with its vibrant, clover-like leaves and charming blooms, is a beloved addition to many gardens. But did you know that this captivating plant can also be easily propagated from seed? This blog post will guide you through the process of how to harvest oxalis seeds, ensuring you have a plentiful supply for future gardens.
Understanding Oxalis Seed Pods
The key to successful oxalis seed harvesting lies in recognizing the seed pods. These pods, which emerge after the flowers fade, are typically triangular or heart-shaped and contain numerous tiny, black seeds. The pods can range in color from green to brown, depending on the oxalis species.
The Timing is Crucial: When to Harvest Oxalis Seeds
The ideal time to harvest oxalis seeds is when the seed pods have fully matured and turned brown or have begun to split open. This usually occurs several weeks after flowering. If you wait too long, the pods might burst open, scattering the seeds across your garden.
Harvesting Oxalis Seeds: A Step-by-Step Guide
1. Choose the Right Pods: Select mature seed pods that are dry and have turned brown. Avoid picking pods that are still green or have not fully developed.
2. Gentle Extraction: Carefully detach the seed pods from the plant. You can gently twist the pods off or use a pair of scissors to snip them at the base.
3. Drying the Pods: Spread the harvested seed pods on a piece of paper or a tray in a dry, well-ventilated area. Allow them to dry completely for several days or until they become brittle.
4. Seed Release: Once the pods are fully dry, they will easily release their seeds. You can gently rub the pods between your fingers to extract the seeds, or you can place the pods in a paper bag and shake them vigorously.
5. Storing the Seeds: Store the harvested oxalis seeds in a cool, dry, and dark place. They can be kept in an airtight container or paper envelope.
Tips for Successful Oxalis Seed Harvesting
- Avoid Over-Watering: Allow the soil to dry slightly between waterings to encourage seed pod formation.
- Deadheading: Remove spent flowers to encourage the plant to produce more seed pods.
- Observe the Pods: Regularly check the seed pods for signs of maturity.
Sowing Oxalis Seeds: Bringing New Life to Your Garden
Once you have harvested your oxalis seeds, you can sow them directly into the garden or start them indoors.
Direct Sowing: Sow the seeds in a well-prepared seedbed or pot. Cover the seeds lightly with soil and water gently. Keep the soil consistently moist until germination occurs.
Indoor Starting: Fill seed trays or pots with a seed-starting mix. Sow the seeds on the surface of the mix and mist them with water. Cover the tray or pot with a plastic dome or wrap to maintain humidity. Place the tray in a bright, warm location.
Oxalis Seed Germination and Growth
Oxalis seeds typically germinate within 2-4 weeks. Keep the seedlings moist and provide them with plenty of light. Once the seedlings have developed a few true leaves, you can transplant them to their permanent location in the garden.
Oxalis Seed Harvesting: A Rewarding Experience
Harvesting oxalis seeds is a rewarding experience that allows you to enjoy the beauty of this plant year after year. By following these simple steps, you can easily collect and store seeds, ensuring a bountiful supply for future gardens.
Beyond the Garden: The Versatility of Oxalis Seeds
While oxalis seeds are primarily used for propagation, they also have other applications:
- Culinary Uses: Some oxalis species, like the wood sorrel (Oxalis acetosella), have edible leaves and flowers that can be used in salads or as a garnish. However, it’s crucial to identify the species carefully, as some oxalis varieties are toxic.
- Medicinal Properties: Certain oxalis species have been used in traditional medicine for their anti-inflammatory and antioxidant properties.
Answers to Your Questions
Q: How long do oxalis seeds remain viable?
A: Oxalis seeds can remain viable for several years if stored properly in cool, dry, and dark conditions.
Q: Can I harvest oxalis seeds from purchased plants?
A: Yes, you can harvest oxalis seeds from purchased plants. However, be aware that the plant’s variety may not be true to type if it was propagated from seed.
Q: What are the best conditions for oxalis seed germination?
A: Oxalis seeds germinate best in warm temperatures (around 70-75°F) and with consistent moisture. They also need bright, indirect light.
Q: Can I store oxalis seed pods for later use?
A: It’s best to extract the seeds from the pods as soon as they are dry. Storing the pods for an extended period can lead to seed deterioration.
Q: Is it necessary to scarify oxalis seeds before sowing?
A: Oxalis seeds have a hard seed coat that can hinder germination. Scarifying the seeds by lightly nicking the coat with a sharp knife or sandpaper can improve germination rates.
