|HARVESTING AND STORAGE
You can harvest as soon as leaves start to yellow, but the longer a crop is left in the ground, the higher the yield and vitamin content. Once frost blackens the vines, however, tubers can quickly rot.
Use a spading fork to dig tubers on a sunny day when the soil is dry. Remember that tubers can grow a foot or more from the plant, and that any nicks on their tender skins will encourage spoilage. Dry tubers in the sun for several hours, then move them to a well-ventilated spot and keep at 29ºC to 32ºC for 10 to 15 days. After they are cured, store at around 13ºC, with a humidity of 75 to 80 percent. Properly cured and stored sweet potatoes will keep for several months
