How do you bank sweet potatoes with straw?

You can't technically "bank" sweet potatoes with straw like you would with potatoes.

Here's why:

* Sweet potatoes need warm temperatures: They are a tropical plant and need a warmer temperature than potatoes to store properly. Straw doesn't provide sufficient insulation to keep sweet potatoes warm.

* Straw can harbor pests: Straw can attract pests like rodents and insects that could damage your sweet potatoes.

* Sweet potatoes need humidity: They need a certain level of humidity to prevent them from drying out. Straw doesn't provide this.

Here's how to store sweet potatoes properly:

1. Cure them: After harvesting, let your sweet potatoes cure in a warm, dry place (around 80-85 degrees Fahrenheit) for 7-10 days. This allows them to develop their sweetness and improve storage life.

2. Store in a cool, dry place: Once cured, store sweet potatoes in a cool, dry, well-ventilated area, like a root cellar or basement. The ideal temperature is 55-60 degrees Fahrenheit.

3. Keep them away from light: Light can cause them to sprout and spoil.

4. Store in a breathable container: Use a basket, box, or paper bag to store your sweet potatoes. Avoid plastic containers, as they can trap moisture and lead to spoilage.

Instead of straw, you could use:

* Sand: This is a traditional method that provides good drainage and keeps the sweet potatoes dry.

* Vermiculite: This is a lightweight, inorganic material that can absorb moisture and help regulate humidity.

Remember, proper storage is key to keeping sweet potatoes fresh for several months.
