Why Harvest and Store Herb Seeds?

  • Cost Savings: Save money by reusing seeds from your current plants.
  • Sustainability: Reduce waste and contribute to sustainable gardening practices.
  • Customization: Preserve unique plant varieties and traits that work well in your garden.

Choosing the Right Time to Harvest Seeds

Seeds should be harvested when they are fully mature. This is typically when the seed heads or pods have dried out and turned brown but before they start to disperse naturally.

Season

Most herbs will produce seeds towards the end of their growing season. Keep an eye on your plants as they flower and begin to set seeds.

Tools and Supplies Needed

  • Clean scissors or pruning shears
  • Paper bags or envelopes
  • Labels and markers
  • Drying screens or trays
  • Airtight containers (e.g., glass jars with tight-fitting lids)

Steps for Harvesting Herb Seeds

Look for seed heads or pods that are dry and brown. Examples include the flower heads of basil, dill, and cilantro, or the seed pods of beans and peas.

Collect the Seeds

Use clean scissors or pruning shears to cut the seed heads or pods from the plant. Place them in a paper bag or envelope to avoid losing any seeds during transport.

Dry the Seeds

Spread the seed heads or pods in a single layer on a drying screen or tray. Place them in a well-ventilated, dry area away from direct sunlight. Allow them to dry completely, which may take one to two weeks.

Extract the Seeds

Once the seed heads or pods are fully dry, gently crush them to release the seeds. Use your fingers or a small tool to separate the seeds from the chaff (the non-seed material).

Clean the Seeds

Remove any remaining debris by winnowing the seeds. Pour the seeds between two containers in front of a gentle fan or breeze. The lighter chaff will blow away, leaving the heavier seeds behind.

Storing Your Herb Seeds

Place the cleaned seeds in labeled envelopes or small paper bags. Include the herb name, variety, and date of harvest on each label.

Choose Storage Containers

Transfer the labeled envelopes or bags to airtight containers. Glass jars with tight-fitting lids work well to keep moisture and pests out.

Ideal Storage Conditions

Store the containers in a cool, dark, and dry location. An ideal storage area should maintain a consistent temperature of around 40-50°F (4-10°C) with low humidity. A refrigerator can be a good option if space allows.

Monitor Stored Seeds

Check your stored seeds periodically to ensure they remain dry and free from mold or pests. Discard any seeds that show signs of damage or contamination.

Testing Seed Viability

To ensure your stored seeds remain viable, perform a germination test before planting:

  1. Dampen: Moisten a paper towel and place 10 seeds on it.
  2. Wrap: Fold the paper towel over the seeds and place it in a plastic bag.
  3. Wait: Keep the bag in a warm location and check for germination after a week.
  4. Calculate: Count how many seeds have sprouted. A germination rate above 70% indicates good viability.
