5 Storage Tote Requirements For Storing Harvested Potatoes Old-Timers Swear By

You’ve just turned over the last forkful of soil, and the wheelbarrow is brimming with beautiful, dirt-caked potatoes. It’s a satisfying moment that represents months of work. But the job is only half done; getting those spuds to last through the winter is the real challenge. The right storage container isn’t just a box—it’s the single most important tool for preserving your harvest.

Why Proper Curing Is the First Step to Storage

Before a single potato goes into a tote, it needs to be cured. This isn’t an optional step; it’s the foundation for successful long-term storage. Curing is the process of letting the potatoes rest in a specific environment to toughen up their skins and heal any minor cuts or bruises from harvesting.

Think of it as creating a protective callus. For about one to two weeks, keep your potatoes in a dark, relatively humid place with a temperature around 60°F (15°C). A garage or a covered porch out of direct sun often works well. This brief period allows the potato’s skin to thicken, sealing out the bacteria and fungi that cause rot later on.

Skipping this step is like putting a boat in the water with holes in the hull. No matter how perfect your storage tote is, uncured potatoes are vulnerable. They will shrivel, sprout, or rot far more quickly, turning your hard-earned harvest into a disappointing waste.

Requirement 1: A Tote Must Provide Total Darkness

Light is the enemy of a stored potato. Exposure to any light, even for short periods, triggers the production of two things you don’t want: chlorophyll and solanine. Chlorophyll turns the potato’s skin green, which is harmless but a clear warning sign.

The real problem is solanine, a bitter-tasting glycoalkaloid that can cause digestive upset in humans. While you’d have to eat a lot of green potatoes to get seriously ill, it’s a compound best avoided. Total darkness prevents this process entirely, keeping your potatoes safe and palatable.

Your storage tote, therefore, must be completely opaque and preferably have a lid. A simple burlap sack works because the weave is tight enough to block light. A wooden crate is excellent, but it must be stored in a pitch-black root cellar or closet. A tote that lets in any light is a tote that will ruin your potatoes.

Requirement 2: Ensure Excellent Airflow on All Sides

Potatoes are living organisms, and they need to breathe. After curing, they enter a dormant state where they respire slowly, releasing a small amount of moisture and carbon dioxide. If this moisture gets trapped, it creates the perfect damp environment for mold, mildew, and bacterial rot to thrive.

This is why those solid plastic tubs with snap-on lids are a terrible choice for potatoes, even if they’re dark. They create a sealed, stagnant environment. You need a container that allows air to circulate freely around every single potato. This means slatted sides, a slatted bottom, and even space between stacked containers.

Look for wooden crates with gaps between the slats or sturdy wire mesh baskets. If you must use a container with solid sides, make sure it’s very shallow and don’t put a lid on it (as long as the room is dark). A great old-timer trick is to place your crates on a couple of bricks to ensure air can get underneath the bottom tote, which is often the first place moisture problems start.

Requirement 3: Choose Natural, Breathable Materials

The material of your tote matters just as much as its design. Old-timers almost exclusively used wooden crates, wicker baskets, or burlap sacks for a reason: these materials breathe. They don’t trap condensation the way non-porous materials do.

Here’s a quick breakdown of common options:

• Wood: The gold standard. It’s strong, breathable, and durable. Untreated pine or poplar crates are ideal.
• Burlap: Excellent for its breathability and light-blocking ability. It offers less protection from crushing, however.
• Wicker/Woven Baskets: Great for airflow, but can be less durable and harder to stack than wooden crates.
• Plastic: Use with extreme caution. If you opt for plastic, it must be a heavily ventilated crate-style design, not a solid bin. Plastic is easy to clean but is unforgiving if airflow is compromised.

While a plastic crate might be cheaper, wood is a better long-term investment for your harvest. It naturally helps regulate moisture and provides the sturdy, breathable home your potatoes need to last until spring.

Requirement 4: Shallow Depth to Prevent Crushing

It’s tempting to find one giant bin and dump your entire harvest inside. This is a critical mistake. Potatoes are heavy, and their own weight can be their undoing. The spuds at the bottom of a deep pile will be bruised and crushed by the weight of those on top.

A bruise on a potato is more than a cosmetic flaw; it’s a broken cell wall. This injury becomes an open door for rot-causing pathogens. Once rot starts in one potato, it can quickly spread through the entire pile, especially in a container with poor airflow.

The solution is to keep your layers of potatoes shallow, no more than about 6 to 8 inches deep. This is why stacking shallow crates is a far superior method to using one deep bin. Each crate supports its own weight, protecting the potatoes below and ensuring good airflow throughout the entire stack.

Requirement 5: Sturdy Construction for a Heavy Load

Never underestimate the weight of potatoes. A bushel of potatoes weighs around 60 pounds. A flimsy cardboard box or a cheap, flexible plastic tote simply won’t hold up. The sides will bow, the bottom may break, and if you try to stack them, the whole structure could collapse.

A good storage tote needs to be rigid and robust. Look for crates built with thick wood, reinforced corners, and solid joinery. If you lift the empty container, it should feel substantial, not flimsy. This isn’t just about preventing a spill; it’s about protecting the potatoes.

A flexing container puts uneven pressure on the contents, leading to bruising. A sturdy, unyielding crate maintains its shape, distributing the load evenly and keeping the potatoes safe. Your tote should be strong enough that you can stack several of them full without worrying about the one on the bottom buckling.

Layering with Straw or Newspaper to Manage Moisture

Even in a cool, dark cellar, temperature and humidity can fluctuate. A great way to buffer your potatoes against these changes is to layer them with a dry, absorbent material. This practice serves two key purposes: moisture management and separation.

Clean, dry straw is a fantastic choice. So is shredded newspaper (avoiding glossy, colored pages). As you fill your shallow crates, place a layer of potatoes, then a loose layer of straw or paper, and repeat. This material will wick away any excess moisture that might condense on the potatoes, keeping their skins dry.

This layering technique also helps isolate problems. If one potato does begin to rot, the surrounding absorbent material can help contain the moisture and slow its spread to neighboring spuds. It’s a simple, low-cost insurance policy for your harvest.

The Critical Mistake of Washing Before Storing

After digging up potatoes, they are covered in soil. The instinct to give them a good wash is strong, but you must resist it. Washing potatoes before storing them is one of the fastest ways to guarantee a rotten mess in a few months.

The soil clinging to the potatoes is not dirt; it’s a protective layer. More importantly, the potato’s skin is a natural barrier, and washing introduces moisture that can seep into tiny, invisible nicks and abrasions from harvesting. This dampness is an open invitation for bacteria and mold.

Instead of washing, let the potatoes air dry for a few hours after digging (out of direct sun). Once the soil is dry and crumbly, gently brush off the large clumps with your hands or a soft brush. Leave a thin film of dry soil on the skins. You can wash them right before you’re ready to cook them, but not a moment sooner.

Ultimately, preserving your potato harvest comes down to mimicking the conditions of the earth they grew in: dark, cool, breathable, and not too damp. Your storage tote isn’t just a container; it’s a carefully chosen habitat. By selecting a sturdy, shallow, and well-ventilated tote made from natural materials, you’re not just storing food—you’re honoring the work it took to grow it.
