If you want to give new life to your garden, bury the onions in a glass with soil. Here’s what happens.

Onions , one of the basic ingredients of the recipes most loved by Italians. Growing them at home , however, seems like an unattainable challenge to many , especially since many don’t have an adequate space to do it. The good news, however, is: there is a trick that allows you to grow onions directly inside the house, even in tiny spaces , like a plastic cup .

The hidden benefits of onions

Onions are very common vegetables in Italy, where we find them in different varieties : red, white, golden and so on. In addition to being versatile and tasty , however, onions also boast particular benefits for our health .

Raw onions, for starters, are low-calorie and contain essential micronutrients like B vitamins, phosphorus, and potassium . In addition, they contain a good amount of fiber , including fructans , which are useful for the health of the gastro-intestinal system . But that’s not all: onions are rich in vitamin C, essential for the synthesis of elements such as hormones and proteins , as well as for the health of the immune system .

In addition to these elements that we have listed briefly, onions are foods rich in folic acid, phosphorus, calcium, vitamin B6 and potassium . This causes them to act beneficially in different areas of our body . For example, they have an antimicrobial action that allows you to better fight bacterial infections from Escherichia coli, Staphylococcus aureus and Helicobacter pylori.

Again, onions are able to bring down blood sugar levels , with beneficial effects on blood sugar . Indeed, a study dated 2010 has shown that consuming 100 grams of raw red onions every day is able to improve the glycemic levels of patients suffering from diabetes . A real panacea for health!

How to plant onions in a plastic cup

How is it possible that onion plants grow inside plastic cups ? There are several videos on Youtube in which botanist experts illustrate this trick. The procedure to follow is quick and simple , and allows you to start seeing results after the first 7 days of cultivation.

As for the materials , we will need a transparent plastic cup , or alternatively a vase . In addition, we will need a box cutter or a screwdriver , some soil , onions and a knife .

To start, cut the onions flat, removing the cap but not the roots , which will be essential for what we are going to do. Then we create small holes in the bottom and on the walls of the pots and fill them with soil . In doing this, however, we leave some space between the soil and the edge of the pot , about a couple of centimeters.

Once this is done, we shape the surface of the soil with our fingers in order to create a small ditch in the center, inside which we will plant an onion . As for the position of the onion, it should be remembered that it should be placed with the roots downwards. Finally, place the pots in containers or saucers , and water every two days or so.

Continuing to water we will notice the first green leaves appearing after about 7 days , a good sign for the growth of our onion plants !
