How do you dry seeds to plant?

Published in Seed Saving 3 mins read

To dry seeds for planting, spread them in a single layer in a warm, dry place, ensuring the temperature doesn't exceed 95°F.

Here's a breakdown of how to dry seeds properly:

Steps for Drying Seeds:

  1. Preparation: After collecting seeds, remove any excess pulp or debris. Clean seeds dry better and are less prone to mold.

  2. Single Layer: Spread the seeds in a single layer on a clean, dry surface. Good options include:

    • Paper towels
    • Screens or mesh
    • Coffee filters
    • Plates

  3. Environment: Place the seeds in a warm, dry, and well-ventilated area. Good airflow helps prevent mold.

  4. Temperature: Keep the temperature below 95°F (35°C). Excessive heat can damage the seeds and reduce their viability.

  5. Duration: The drying time varies depending on the seed type and humidity levels. Generally, seeds need to dry for a few days to a couple of weeks. Check them regularly. Seeds are dry when they are brittle and snap instead of bend.

  6. Turning/Mixing: Gently turn or mix the seeds periodically to ensure even drying.

Things to Avoid:

  • Direct Sunlight: Avoid direct sunlight, as it can overheat and damage the seeds.
  • High Humidity: Do not dry seeds in areas with high humidity, as this will slow the drying process and promote mold growth.
  • Ovens or Dehydrators: Avoid using ovens or dehydrators unless you can maintain a consistently low temperature (below 95°F). Even on the lowest setting, these appliances can easily overheat seeds.
  • Airtight Containers: Do not store seeds in airtight containers until they are completely dry. Doing so can trap moisture and cause mold.

Determining Dryness:

  • Snap Test: A simple way to test if seeds are dry enough is the "snap test." Take a few seeds and try to bend them. If they snap instead of bend, they are likely dry enough for storage.
  • Feel: Dry seeds should feel hard and brittle.

Storage:

Once the seeds are completely dry, store them in an airtight container in a cool, dark, and dry place. A refrigerator or freezer is ideal for long-term storage. Label the container with the seed type and date of collection.
