Sweet Potato Storage Tips: Keep These Methods in Mind
1. Types of storage cellars: Sweet potatoes are stored in vertical shaft cellars, which are generally 4.5-5 m deep, with a soil layer 2.5-3 m thick above the cellar chamber. 2. Disinfection of the storage cellar: Store seed potatoes in a sterile cellar; it is best to use a new cellar. If an old cellar is used, scrape 3-4 cm off the walls and floor to expose fresh soil.
