How to Save Seeds from Yardlong Bean Plants

Yardlong beans, scientifically known as Vigna unguiculata subsp. sesquipedalis, are a type of legume that produce long, slender pods. Saving seeds from yardlong bean plants is a great way to preserve their unique characteristics and ensure a continuous supply of these delicious and nutritious beans in your garden. Here is a step-by-step guide on how to save seeds from yardlong bean plants:

1. Selecting the Right Plants

Choose healthy and vigorous yardlong bean plants for seed saving. Look for plants that have produced high-quality beans with desirable traits such as length, color, and taste. Avoid plants that show signs of disease or pest damage.

2. Allowing Pods to Mature

Allow the yardlong bean pods to fully mature on the plant. The pods will turn dry and brittle, and the beans inside will become hard and fully developed. This usually takes around 80-100 days after planting, depending on the variety and growing conditions.

3. Harvesting the Pods

Once the pods have dried on the plant, carefully remove them by hand. Avoid shelling the beans at this stage, as it is best to keep them inside the pods until further processing.

4. Threshing the Pods

Threshing is the process of separating the beans from the dried pods. Place the pods in a clean, dry container and gently crush them using your hands or a pestle. This will help loosen the beans from the pods.

5. Winnowing the Seeds

Winnowing is the process of separating the seeds from the chaff or debris. Take the crushed pods outdoors on a windy day or use a fan indoors. Pour the crushed pods from one container to another while allowing the wind or fan to blow away the lighter chaff, leaving behind the heavier seeds.

6. Cleaning and Drying the Seeds

After winnowing, inspect the seeds for any remaining debris or damaged beans. Remove any unwanted materials and transfer the clean seeds to a dry, well-ventilated area. Spread them out on a clean tray or screen and allow them to air dry completely. This may take a few days to a week, depending on the humidity levels.

7. Storing the Seeds

Once the seeds are completely dry, store them in airtight containers such as glass jars or seed envelopes. Label the containers with the variety and date of collection to keep track of the seeds. Store the containers in a cool, dark, and dry place to maintain seed viability.
