Potatoes are one of the most versatile and loved staples in the kitchen, but how do you store potatoes the right way to make them last? Whether you’ve just dug up a harvest from your garden or grabbed a big bag at the store, knowing how to keep potatoes fresh is key to avoiding waste and maximizing their lifespan.
How to Best Store Potatoes
So, how do you keep potatoes from sprouting too soon or going soft? The trick lies in storing them in the right conditions. Potatoes are best kept in a cool, dark, and well-ventilated space. Aim for a temperature range of 45°F to 50°F (7°C to 10°C). This helps slow down any sprouting or rotting.
Tip: Don’t store potatoes in the fridge! While it seems logical, colder temperatures can turn the starches into sugar, affecting the taste and texture when cooked.
What to Avoid When Storing Potatoes
- Keep potatoes away from onions. Yes, they may seem like pantry pals, but onions emit gases that speed up potato sprouting.
- Do not wash your potatoes. Moisture is the enemy of long-term potato storage. So never get them wet until you’re ready to start cooking.
- Avoid plastic bags. These trap moisture, causing potatoes to spoil faster. Instead, opt for a breathable container like a paper bag, a basket, or a cardboard box.
How Long Do Potatoes Last?
How long will potatoes keep? This depends on the type and storage conditions. In optimal environments, potatoes can last several weeks to a few months. Here’s a quick breakdown:
- Sweet Potatoes: Though technically not potatoes, they can last 2-3 weeks at room temperature and a bit longer in cooler spots.
- New Potatoes: These thinner-skinned varieties last about 1-2 weeks.
- Mature Potatoes: With thicker skins, they can last 1-3 months if stored correctly.
Curing homegrown potatoes helps develop a thicker skin, allowing them to be stored longer.

Tips for Saving Potatoes
To extend the shelf life further, check your stored potatoes regularly. Remove any that show signs of sprouting or rotting, as one bad potato can spoil the bunch. If you find potatoes beginning to sprout but still firm, cut off the sprouts and use them soon.
One caveat is that if it’s the right time of year and you find your potatoes sprouting, you might be able to plant them. This process of encouraging your potatoes to sprout is called “chitting.”

How to Keep Potatoes from Sprouting
Sprouting can be slowed down by ensuring your storage space is dry and well-ventilated. If you’re worried about sprouting, you can place an apple with your potatoes. Apples release ethylene gas, which helps inhibit sprouting. Just be careful not to overdo it, as too much ethylene can lead to premature spoilage.
Final Thoughts on How to Save Potatoes
With the right setup, learning how to save potatoes becomes easy. Store them in a cool, dark, dry space, them frequently and avoid moisture at all costs. This way, you can enjoy your potatoes at their best for weeks—or even months—to come.
Happy Growing!
