To store bitter gourd seeds for the next season, dry them thoroughly, place them in an airtight container, and store them in a cool, dark, and dry place.
Storing bitter gourd seeds properly ensures a higher germination rate when you plant them next season. Here's a step-by-step guide:
Harvest Mature Gourds: Allow the bitter gourds to fully mature on the vine. They should turn orange or yellow. This indicates the seeds inside are fully developed.
Extract the Seeds: Cut open the mature gourds and scoop out the seeds. Remove any pulp or fleshy material attached to the seeds.
Clean the Seeds: Wash the seeds thoroughly under running water to remove any remaining pulp. This helps prevent mold growth during storage.
Dry the Seeds: Spread the cleaned seeds in a single layer on a clean, dry surface, such as a paper towel or a screen. Allow them to air dry completely. This may take several days, depending on the humidity. Ensure the seeds are completely dry to prevent fungal growth. You can also use a dehydrator at a low temperature setting.
Test for Dryness: The seeds should be hard and brittle when they are completely dry. You should not be able to bend or dent them easily.
Store the Seeds: Place the dried seeds in an airtight container, such as a glass jar or a resealable plastic bag. You can add a desiccant packet (silica gel) to absorb any residual moisture. Label the container with the date and variety of the seeds.
Choose a Storage Location: Store the container in a cool, dark, and dry place. A refrigerator (not the freezer) is an excellent option, as the low temperature and humidity help preserve the seeds' viability. A basement or a cool pantry can also work.
Before planting, you can test the viability of your stored seeds by placing a few seeds between damp paper towels. Keep the paper towels moist and warm. If most of the seeds germinate within a week, your stored seeds are still viable. If germination rates are low, consider using fresh seeds for better results.
