How long does it take for potatoes to sprout?

It is not always recommended, but few farmers prefer to sprout the seed potatoes before planting them. This process of sprouting is often referred to as green sprouting or pipping. The seed potatoes to be used for planting are initially spread under the sunlight such that the temperature is around 70°F for a week or two. This enables to produce sprouts on the potatoes, which can be used for planting. The average sprouting time is estimated to be 14 to 28 days if the potatoes are directly planted into the soil with proper warmth.
