Potatoes are one of the most popular vegetables in UK kitchens, but if they are not stored correctly they can sprout, turn green or begin to rot. Knowing how to store potatoes properly will help you make the most of your harvest or shop-bought supply. In this guide we will cover the best storage methods, ideal conditions and the right sacks to use for keeping potatoes fresh for months.
Why Is Storing Potatoes Correctly Important
Potatoes are living vegetables and continue to respire after harvest. Without proper storage they will sprout, soften and develop green patches that make them unsuitable for eating. By giving potatoes the right conditions you can extend their storage life for up to six months, reduce food waste and enjoy a reliable supply throughout the year.
What Temperature Is Best For Storing Potatoes
Potatoes should be stored in a cool dark place with a temperature below 10 degrees celsius. A shed, garage, pantry or cellar usually provides the right environment. Avoid fridges as the cold temperature can change the starch in potatoes into sugar, which affects taste and texture.
Which Bags Or Sacks Should I Use To Store Potatoes
The type of sack you choose makes a big difference to how long potatoes will last. Hessian potato sacks are one of the best options as the woven fabric allows air to flow, preventing sweating and reducing the chance of rot. They are reusable, washable and compostable at the end of their life. Paper potato sacks are another popular choice. The breathable paper lets air circulate while keeping out light, helping potatoes stay fresh. Both types are available in different sizes, such as 25kg or 50kg capacity, making them suitable for gardens and households of all sizes.
How To Prepare Potatoes Before Storing
Always check potatoes before placing them into a sack. Make sure they are dry and free from soil clumps. Remove any potatoes that are damaged, bruised or already sprouting as they can affect the rest of the crop. Allowing them to air dry for a few hours before storage will reduce moisture and help keep them in good condition.
Where Should I Keep My Potato Sacks
Store sacks of potatoes in a cool, dark and well ventilated place. Keep them away from direct sunlight and do not stack them tightly against walls as airflow is essential. Avoid storing potatoes next to onions as they release gases that can cause potatoes to sprout faster.
How Long Can Potatoes Be Stored In Sacks
When kept in the correct conditions, potatoes can last up to 6 months. However, it is important to check them regularly. Remove any potatoes that are soft, sprouting or damaged to prevent them from spoiling the rest. Regular checks will help extend the storage life of the whole sack.
Can Potato Sacks Be Used For Other Vegetables
Yes, both hessian potato sacks and paper potato sacks can also be used to store other root vegetables such as carrots, onions and parsnips. The breathable materials make them a good all-round choice for gardeners who want to store a variety of crops.
