In this brief guide, we will discuss the following question, “how far apart to store onions and potatoes?”, how to store potatoes and onions, what are the ethylene-producing fruits and vegetables, which are sensitive to ethylene, and other queries related to this topic.

How far apart to store onions and potatoes? 

Potatoes and onions should be stored in different containers and different areas because each one of them needs specific environmental characteristics to be stored for a longer time and to avoid their spoilage.

In addition, one of the reasons behind storing them apart is that onions produce a gas called ethylene. This gas rips the potatoes and spoils them. However, potatoes are very moist, so this will make the onions

How to store potatoes?

Potatoes should be stored in a cool, dry, and dark place like in the cabinet or the pantry and in an appropriate container that allows ventilation, far from any fruit or vegetable that emits the ethylene gas. If the place where the potatoes are placed is suitable it can last for 5 months.

Also, make sure you cover the container very well. Because light and sun exposure will deteriorate your potatoes and lead to the green color formation on the skin and within the potato. When the potato turns green, it indicates the presence of solanine.

Solanine is naturally present in potatoes, and when they are exposed to sunlight the solanine concentration will increase. This compound is neurotoxic when ingested in large quantities and leads to poisoning. Moreover, solanine poisoning symptoms are diarrhea, vomiting, headache, fever, and abdominal cramps.

Furthermore, avoid placing your potatoes in a warm place like near the oven or the refrigerator since the hot temperatures will increase the chance of your potatoes sprouting.

How to store onions?

Onions should be stored in a dry place, in a basket that allows air circulation and can last for 3 months. Make sure to not store your onions in a plastic bag or the refrigerator unless you have already peeled them, so you can store them for about 2 weeks.

However, green onions should be stored in the fridge. To do so, wash them, cut their roots, wrap them in a towel or paper and finally put the green onions with the towel in a bag in the fridge.

Can I store potatoes with garlic?

No, it is not preferred to store potatoes with garlic in the same basket. Because garlic produces ethylene, like onions, which can spoil the potatoes. Very similar to onions, garlic should be stored in a dry and well-ventilated place at room temperature. However, do not remove the outer papers until you are planning to use them in your recipe.

Furthermore, you might notice that your garlic cloves are sprouting or developing green leaves in the middle. So, just remove them and use the other part since it is very safe for consumption.

What is ethylene gas?

Ethylene gas is a hormone present in the plant. It helps in the plant’s growth and increases the fruit’s ripening process. This gas is also known as the “fruit-ripening hormone”. Moreover, ethylene emission by some fruits will ripen other fruits that do not emit ethylene, faster when placed in the same bowl.
