You can store potatoes with some other vegetables, but it’s generally not recommended to store them with most. Potatoes release ethylene gas, which can cause other produce to spoil faster. They also prefer cool, dark, and humid conditions, which differ from the needs of many other vegetables.
Storing Potatoes: What to Keep Them Away From
Understanding how to properly store potatoes is key to extending their shelf life and preventing spoilage. While you might be tempted to toss all your harvested produce into one bin, certain vegetables can negatively impact your potatoes, and vice versa. This guide will help you navigate the best practices for keeping your potatoes fresh and your other vegetables from premature decay.
Why Potatoes Need Special Storage
Potatoes are root vegetables that thrive in specific environmental conditions. They need a cool, dark, and humid place to maintain their quality. Temperatures that are too warm can cause them to sprout or turn green, while exposure to light can lead to solanine production, making them bitter and potentially toxic. Humidity helps prevent them from drying out.
Vegetables That Should NOT Be Stored With Potatoes
The primary reason to keep potatoes separate from most other vegetables is the ethylene gas they produce. Ethylene is a natural plant hormone that accelerates ripening and, consequently, spoilage in susceptible produce. Many common vegetables are sensitive to this gas.
Here are some key culprits to keep away from your spuds:
- Onions and Garlic: These are perhaps the most common companions that should be avoided. Onions and potatoes both release moisture and gases that can lead to faster spoilage when stored together. The moisture from potatoes can make onions rot, and the gases from onions can make potatoes sprout.
- Apples: Apples are high ethylene producers. Storing them with potatoes will cause the potatoes to sprout and soften much more quickly.
- Bananas: Similar to apples, bananas are significant ethylene producers and will hasten the spoilage of potatoes.
- Tomatoes: Tomatoes are also sensitive to ethylene and will ripen too quickly, becoming mealy when stored near potatoes.
- Avocados: While avocados ripen off the plant, they also produce ethylene and can be negatively affected by being stored with potatoes.
- Stone Fruits (Peaches, Plums, etc.): These fruits release a considerable amount of ethylene gas as they ripen.
Vegetables That Might Be Stored Near Potatoes (With Caution)
While it’s best to err on the side of caution, some vegetables are less sensitive to ethylene gas or have similar storage needs. However, cross-contamination is still a risk, so separation is always the safest bet.
- Root Vegetables (Carrots, Beets, Parsnips): These have similar storage needs to potatoes – cool and dark. However, they also release moisture. If stored together in a confined space, this moisture can encourage rot in both the potatoes and the other root vegetables. If you must store them nearby, ensure excellent ventilation.
- Winter Squash (Butternut, Acorn, Spaghetti): These prefer slightly warmer and drier conditions than potatoes, so direct storage together isn’t ideal. However, they are not highly sensitive to ethylene.
Optimal Storage Conditions for Potatoes
To maximize the lifespan of your potatoes, follow these best practices:
- Cool Environment: Aim for a temperature between 45-55°F (7-13°C). A basement, root cellar, or unheated garage can be ideal. Avoid refrigerating potatoes, as the cold converts their starch to sugar, affecting taste and texture, and can cause them to turn brown when cooked.
- Darkness: Keep potatoes in a completely dark place. Light encourages the production of chlorophyll (turning them green) and solanine. Use burlap sacks, paper bags, or store them in a dark cupboard.
- Good Ventilation: Potatoes need to breathe. Store them in a well-ventilated container like a basket, bin with holes, or a mesh bag. Avoid plastic bags, which trap moisture and can lead to rotting.
- Avoid Washing: Do not wash potatoes before storing them. The moisture can promote spoilage. Brush off excess dirt gently.
Comparing Storage Needs for Common Produce
It’s helpful to see how potato storage differs from other popular vegetables. This comparison highlights why they often shouldn’t share the same space.
| Vegetable Type | Ideal Temperature | Light Preference | Ethylene Sensitivity | Best Storage Method |
|---|---|---|---|---|
| Potatoes | 45-55°F (7-13°C) | Dark | Moderate | Cool, dark, humid, well-ventilated, unwashed |
| Onions & Garlic | 40-50°F (4-10°C) | Dark | Low | Cool, dry, dark, excellent air circulation, cured |
| Tomatoes | 55-70°F (13-21°C) | Room Temperature | High | Room temperature, out of direct sunlight, unwashed |
| Leafy Greens | 32-40°F (0-4°C) | N/A (in fridge) | High | Refrigerated, in a perforated bag or container |
| Apples | 30-35°F (-1-2°C) | N/A (in fridge) | Very High | Refrigerated, in a plastic bag |
Practical Tips for Potato Storage
- Inspect Regularly: Check your stored potatoes periodically for any signs of sprouting, softness, or greening. Remove any bad ones immediately to prevent them from affecting the others.
- Use Them Up: The best way to avoid spoilage is to use your potatoes within a reasonable timeframe. Plan meals that incorporate potatoes to ensure you enjoy them at their freshest.
- Consider Your Space: If you have limited storage space, prioritize separating potatoes from ethylene-producing fruits and vegetables. A simple cardboard box in a cool corner can work if you don’t have a dedicated pantry.
People Also Ask
### Can I store potatoes in the refrigerator?
No, it is not recommended to store potatoes in the refrigerator. The cold temperatures convert their starch into sugar, which can alter their taste and texture, making them sweeter and causing them to turn brown when cooked. They also prefer slightly humid conditions, which refrigerators lack.
### How long can potatoes be stored?
Properly stored potatoes can last for several weeks to several months. Factors like the potato variety, initial condition, and storage environment significantly impact their shelf life. Colder, darker, and well-ventilated conditions will yield the longest storage times.
### What happens if you store potatoes with onions?
Storing potatoes with onions can lead to faster spoilage for both. Potatoes release moisture that can cause
