When do potatoes sprout?

1. Warm temperatures: The ideal temperature for sprouting is between 60°F and 70°F (15°C and 21°C).

2. Light: While potatoes don't need light to grow, exposure to light will encourage sprouting.

3. Moisture: Potatoes need moisture to sprout, so they'll likely sprout faster if they're stored in a humid environment.

4. Time: The amount of time it takes for potatoes to sprout depends on the factors mentioned above. Generally, it takes a few weeks for potatoes to start sprouting.

Here are some additional points to consider:

* Storage conditions: Potatoes stored in warm, humid conditions with access to light will sprout faster.

* Variety: Some potato varieties are more prone to sprouting than others.

* Age: Older potatoes are more likely to sprout.

Note: While sprouting is a natural process, potatoes that have sprouted can become bitter and less desirable to eat. It's best to use sprouted potatoes as soon as possible, or use them for planting.
