As the fall harvest wraps up, many home gardeners and those who love to stock up on fresh produce wonder how to store potatoes and onions for the winter months. These root vegetables are essential in many households, and proper storage ensures you can enjoy them for months to come. I’ll cover the best practices for storing potatoes and onions, keeping them fresh throughout winter. Plus, I’ll answer some frequently asked questions (FAQs) to help you store your produce like a pro.
Best Practices for Storing Potatoes
Potatoes are relatively easy to store, but there are a few key factors to consider for long-lasting freshness:
1. Choose the Right Potatoes
Not all potato varieties store equally well. Some of the best options for winter storage include Russets, Yukon Gold, and Red Potatoes. These have thicker skins and higher starch content, which makes them last longer.
2. Cure Potatoes Before Storing
Curing is an essential step to ensure your potatoes last longer. Once harvested, leave the potatoes in a dark, cool, and well-ventilated area for about two weeks. This helps toughen the skins and heal any minor cuts or bruises that could lead to rot.
3. Store in a Cool, Dark Place
Potatoes should be stored at a temperature between 45°F and 50°F (7°C to 10°C). An ideal spot might be a basement, garage, or root cellar. Avoid storing potatoes in areas where temperatures fluctuate or in warm areas, as this can lead to sprouting or spoiling.
4. Keep Potatoes Dry
Moisture is your enemy when storing potatoes. Store them in a dry environment and avoid washing them before storage. If the potatoes are dirty, gently brush off the dirt, but never rinse them until you’re ready to use them.
5. Allow for Air Circulation
Proper air circulation is critical to prevent mold or rot. Store potatoes in a burlap sack, mesh bag, or a basket that allows air to flow freely. Avoid storing them in plastic bags, which trap moisture and accelerate spoilage.

Best Practices for Storing Onions
Onions, like potatoes, can last all winter when stored properly. Here’s how to keep your onions fresh for months:
1. Select the Right Onions
Storage onions are different from sweet onions. Choose varieties such as Yellow Globe, Red Onions, or White Onions for winter storage. These types have a lower moisture content, making them more resistant to rotting.
2. Cure Onions Properly
After harvesting, onions need to cure before storage. Spread them out in a well-ventilated area, like a garage or shed, for two to three weeks. The outer skins should dry and become papery, which protects the onion during storage.
3. Store in a Cool, Dry Place
Onions should be stored in a cool, dry place with temperatures between 30°F and 40°F (-1°C to 4°C). A pantry, basement, or an unheated room is ideal. Avoid areas with too much moisture, as this can lead to mold and rot.
4. Ensure Proper Ventilation
Like potatoes, onions need plenty of air circulation. Use mesh bags, baskets, or even pantyhose to store your onions. Simply place an onion in the pantyhose, tie a knot, and add another. This method allows airflow and keeps them from touching, reducing the risk of rot.
5. Keep Onions Away from Potatoes
It’s important not to store onions and potatoes together. Potatoes release moisture and gases that can cause onions to spoil faster. Always store these two vegetables separately for best results.

FAQ: Storing Potatoes and Onions for Winter
1. Can you store potatoes and onions together?
No, it’s not recommended to store potatoes and onions together. Potatoes release moisture and gases that can lead to the quick spoilage of onions. Always store them in separate, well-ventilated areas.
2. How long can potatoes last in storage?
When stored properly in a cool, dark, and dry place, potatoes can last for up to six months. Regularly check for any signs of spoilage and remove any sprouted or rotten potatoes to prevent them from affecting the rest.
3. How can I prevent potatoes from sprouting in storage?
To prevent sprouting, keep your potatoes in a cool (but not cold), dark area with good air circulation. You can also place an apple in with the potatoes, as the ethylene gas released by apples can help prevent sprouting.
4. What are the signs that onions are going bad?
Onions will start to soften, develop a strong odor, or show signs of mold when they begin to go bad. Remove any damaged onions immediately to prevent them from spoiling the rest of your stored onions.
5. Can I store potatoes and onions in the refrigerator?
It’s not recommended to store potatoes in the refrigerator, as the cold temperature can cause the starches to turn to sugar, affecting the flavor and texture. Onions can be stored in the fridge, but only after they’ve been cut. Whole onions are best stored in a cool, dry place outside the fridge.
6. Should I wash potatoes and onions before storing them?
No, do not wash potatoes or onions before storing them. Moisture can lead to rot. Instead, gently brush off any dirt and store them as is.
7. How often should I check my stored potatoes and onions?
It’s a good idea to check your stored potatoes and onions every few weeks. Remove any that are sprouting, soft, or starting to spoil to prevent them from affecting the rest of your produce.
Storing Potatoes and Onions for Winter
Storing potatoes and onions for winter doesn’t have to be difficult. By following these tips and ensuring they are kept in the right conditions, you can enjoy your harvest for months to come.
