For picking and storing potatoes for planting next season, you will need:

  • Harvesting – trowel
  • Cleaning potatoes – a soft brush
  • Curing – some trays and newspapers
  • Storage – a dark and cold cellar space, newspapers, cartons

For picking and storing potatoes for cooking

  • Harvesting – trowel
  • Cleaning potatoes – a soft brush
  • Storage – a dark, humid spot

Remember that potatoes taste best when you consume them as early as possible after the harvest. The new potatoes are picked earlier than the ones chosen as a maincrop for planting. Besides the harvesting time, you should also be aware of the best varieties of potatoes that store well. Understanding which variety does well when stored for a long time is a critical step in storage. Recycled cartons and bins are the best choices when it comes to storage. You can also use wooden crates.

Steps to Store Potatoes from The Garden

1. Finding Out the Best Time to Harvest Potatoes

The right time to harvest the potato depends on the application itself. New potatoes are the ones that you harvest to consume immediately. These are the best-tasting potatoes and are harvested early. Roughly 2 months after you plant your potatoes, they might be ready to harvest. Check out for the appearance of flowers.

Within 2 or 3 weeks from the appearance of flowers, your potatoes are ready to harvest for kitchen use.

2. Finding Out the Best Applications for Each Potato Variety

You might already know that there are several varieties of potatoes, and they all taste different. However, did you also know that some of them are not very good to store for a long time? Amarosa, Adirondack blue, and huckleberry gold are some varieties that you cannot store for long.

Yukon gold, German butterball, yukon gem are among the varieties that are known to be the right choice for storage. If you happen to choose the unsuitable varieties, then even the best storage conditions cannot give you good results. Pick your potatoes accordingly to earn a success rate for winter storage. To simplify the concept, most of the red and colored varieties might not store as long as white and yellow varieties. Your potato should also be in the category of the late-maturing types.

3. Harvesting the Potatoes for Cooking

If it is for cooking, you can harvest any variety roughly 60 to 70 days from planting or when flowers begin to appear. If you pick just potato or two, you can do so by slightly lifting the plant and picking your potato. You can then place the plant back in place for it to mature or for the plant to produce more tubers. You can continue picking new potatoes or choose to leave it for maincrop.

Potatoes Field Harvest

Use a trowel if the soil feels too tight. Avoid picking potatoes when the soil is damp, or there is waterlogging. If you do not know whether the taters are ready, you can slightly clear the soil close to the stem to look for stolons. Tubers are close to the stolons below the ground.

4. Harvesting Maincrop Potatoes for Storage

The real confusion comes mostly for those who are picking potatoes for long-duration storage. Gardeners often pick potatoes too early and then face disappointment when the crop doesn’t store for the next season. The key is to wait until the plant wilts. Mature maincrop potatoes need to stay in the plant till the plant is over 100 days old. That is, more than 3 months after the planting time, you might notice the plant wither.

Once the plant is entirely dead, you should wait till the soil is dry. Avoid leaving mature potatoes in the frost, which can lead to the reduced storage success rate. It would help if you also stopped watering the potato vine once it starts showing signs of withering. This lets the potato become firmer and the skin to harden.

5. Cleaning the Potatoes

This step is universal, whether you choose to store it for long or use it soon. Avoid washing the potatoes if you wish to store it. Potatoes for kitchen use can be washed and then stored. Use a soft brush and gently remove the soil. Leaving the potatoes on the ground for some time would let the potato skin dry, which makes the sand from the skin easier to remove.

Do not scrub too hard, or it can create soft spots on the tuber, reducing the shelf life. Remember that before you cure the potatoes, the skin remains tender, and you do not want to cause bruises, which can lead to rotting sooner than expected.

6. Curing Potatoes

If you have noticed freshly harvested potatoes, they are firm on the inside, but the skin feels supple. This is natural when they are under the soil. The curing process is what makes the skin tough and suitable for storage. It is essential to cure the potatoes in an optimal condition if you wish to extend the duration for which the potatoes store well.

Rotten Potatoes Decompose

The ideal temperature for curing is in the range 45℉ to 60℉. It should also be a humid storage space where you leave the potatoes undisturbed for at least 2 weeks. After this, you should notice a significant change in the texture of the skin. If there are superficial cuts that occur during harvest or cleaning, they heal during this curing period. If you find deep cuts and tender spots after the curing period, separate those potatoes and do not put them in the batch that you would be storing for planting. Even the shriveled ones after this period are not fit for storage.

To retain a little moisture, line the storage bins with newspapers. Avoid stacking too many layers vertically to avoid damaging the potatoes. You can line the top with a napkin to block the penetration of light.

7. Picking A Spot for Storage

Potatoes lose their rich taste when you let them stay below 45℉. They also might turn mushy if you pick them from damp soil or leave them out in the garden during the winter. Picking a ventilated yet dark storage corner for the potatoes is the primary step essential to reduce the chances of rot.

They are best stored in separate bins or crates away from other fruits and vegetables to prevent them from sprouting. You do not want the potatoes to lose their moisture content, whether it is for cooking or for winter storage that you plan. Therefore maintaining at least 95% humidity levels is the trick that keeps the potatoes fresh and healthy. Unless there are sprouts that you wish to remove, you should leave the potatoes in their dark corner till you use them.

8. Storing Potatoes for Cooking

To keep potatoes fresh, store them in mesh bags. This can ensure ventilation and preserve the taste. Refrigerator storage is not ideal for potatoes as the humidity levels are low in the fridge.

If you consume potatoes within a few days after picking them, they taste the best. Some stored potatoes tend to taste a little sweet and might need reconditioning for restoring the taste. This is by letting the potatoes rest for a few days away from the cold storage space.

9. Storing Potatoes for The Next Season 

The real deal is to know where and how to store potatoes to keep them fresh and healthy for planting them for the upcoming season. Have you noticed how some people store them along with shredded paper? This is an optimal condition for the winter storage of the maincrop. It helps retain the texture of the potatoes and maintain humidity levels without letting the potatoes go soft. This also helps prevent the drying of the potatoes that can make them appear shrivelled and unhealthy.

Harvested sweet potatoes

Higher humidity levels and lower temperatures away from freezing temperatures are the best conditions for potato storage as long as you can retain steady humidity levels in the range 80-90% and keep the temperatures between 45℉-50℉ and do not let it drop below this. Keep checking your potatoes and separate any soft and rotten ones. Remove sprouts if you store them for a long time. When done right, these potatoes can stay fresh and ready for planting for as long as 9 months. Check the storage life of the potato variety to know how long it can remain good.

10. The Need for A Dark Storage Spot

Keep potatoes in the dark corner of the kitchen, whether you plan to keep it aside for cooking or long storage. Potatoes do not do well when exposed to sunlight. This can lead to solanine build-up, which shows in the form of green spots in the potatoes. These are not just bitter tasting spots but are also not good for your health. Store the potatoes away from light and check for green spots before using them. If there are green spots already present, chop them off to avoid any illnesses caused by consuming them.

General Tips

  • Store potatoes in a dark area
  • Do not place them in the refrigerator
  • Dry air might not be the best fit for long storage
  • Potatoes in which buds appear do not store for long if you do not remove the buds
  • Make sure that you keep potatoes stored away from ripe fruits. The ethylene from the ripening of fruits can lead to the formation of sprouts and therefore shorten the life of potatoes. When this happens, they might not be the best tasting options to consume, and the premature sprouts might make them unfit for planting.
