Introduction to Winged Yams

Winged yams, scientifically known as Dioscorea alata, are a robust and versatile crop that can be a valuable addition to your survival garden. Unlike the toxic Dioscorea bulbifera, winged yams are always safe to eat and produce large, flavorful tubers. This plant thrives in poor soil conditions and requires minimal care, making it an ideal choice for preppers in the Deep South. In this guide, you’ll learn how to grow and harvest winged yams effectively.

Planting Winged Yams

To start your winged yam garden, you’ll need bulbils, which are the small, aerial roots that hang from the vine. These can be planted in the fall, winter, or spring. Choose a location that receives partial shade, as winged yams prefer cooler temperatures and can tolerate some shade. The soil should be well-draining but doesn’t need to be rich; winged yams can grow in poor soil.

  1. Prepare the Soil: Loosen the soil to a depth of about 12 inches. Mix in a layer of compost or aged manure to improve soil structure and fertility. This step is optional but beneficial.
  2. Plant the Bulbils: Dig holes about 2 inches deep and space them 12 to 18 inches apart. Place one bulbil in each hole and cover it with soil. Water the area thoroughly.
  3. Support the Vine: Winged yams are climbing plants and will need support. Install a trellis, fence, or other vertical structure nearby. The vine will naturally attach itself to the support as it grows.

Growing and Harvesting Winged Yams

Once planted, winged yams will emerge in the spring and quickly climb the support structure. The vine will store energy in underground tubers, which can be harvested after one growing season or allowed to grow larger.

  1. Watering: Winged yams require regular watering, especially during dry spells. Aim for about 1 inch of water per week. Water deeply to encourage root growth.
  2. Fertilization: While winged yams can grow in poor soil, a light application of a balanced fertilizer can boost growth. Apply a 10-10-10 fertilizer at a rate of 1 pound per 100 square feet of garden space.
  3. Harvesting: Tubers can be harvested after one growing season or allowed to grow larger. To harvest, gently dig around the base of the plant to uncover the tubers. Be careful not to damage them. You can also wait until the vine starts to die back in the fall, which is a good sign that the tubers are fully developed.

Storing and Using Winged Yams

Winged yams are a high-calorie food source and can be stored for long periods. Proper storage ensures that you have a reliable food supply.

  1. Storage: Clean the tubers thoroughly and allow them to dry. Store them in a cool, dry place with good air circulation. A root cellar or a well-ventilated basement works well. They can be stored for up to six months.
  2. Cooking: Winged yams can be prepared in various ways. They can be boiled, mashed, or roasted. The flavor is similar to a cross between a sweet potato and a regular potato. You can also slice them and fry them for a crispy snack.
  3. Nutritional Value: Winged yams are rich in carbohydrates, which provide energy. They also contain vitamins and minerals, making them a nutritious addition to your diet.

Conclusion

Cultivating winged yams is a smart choice for survival gardening. They are easy to grow, require minimal care, and provide a reliable food source. By following the steps outlined in this guide, you can successfully grow and harvest winged yams for your survival garden.
