Onions are beneficial to your health - learn about their advantages, cultivation, and maintenance

beneficial for respiratory health

Asthma and allergic rhinitis can be alleviated with the use of onion extracts. Onions’ prebiotics can relieve nasal congestion and promote restorative sleep.

Perhaps prevents Alzheimer’s

Onions are especially abundant in the plant compounds flavonoids. According to one study, those who consume a flavonoid-rich diet on a long-term basis are less likely to develop Alzheimer’s disease.

Beneficial for Oral Thrush

The sulphur compounds thiosulfinates and thiosulfonates, which are prevalent in onions, assist in the reduction of tooth decay-causing bacteria. Onions, which are rich in vitamin C, preserve the health of dentition. Additionally, scallions can relieve toothache.

Important for hair regrowth

Onions are rich in antibacterial and antifungal properties, which strengthen and stimulate hair growth. Even on hairless regions, onion juice applied topically to the scalp may prevent greying, thinning, and breakage and stimulate hair growth. Onions promote hair growth and reduce dandruff by enhancing blood circulation in the scalp.

How to effortlessly cultivate onions at home:

Onions require little space and can be cultivated indoors in appealing containers. Onions resprout naturally, so old onion leftovers or spores can be used to grow new onions. Learn the following techniques for cultivating onions: –

From root bulb

The first essential step in this method of onion cultivation is selecting a container with adequate drainage openings that is both deep and wide. Remember that the deeper the container, the larger the onion will grow. And if your container is large enough, you can cultivate many onions. Onions need three inches of space between them. Therefore, you can choose a 6-inch or deeper container, and the breadth can be altered based on the amount of space you need to store.

The container should be filled with potting soil, leaving a 1-inch space. Optionally, combine a nitrogen-rich fertiliser at this stage to improve the grade and girth of the onions.

Now, you must use the portion of the onion that is typically discarded, i.e., the portion from which the onion’s roots develop. Save some of the household scraps you have discarded. You may also use an onion bulb in its entirety.

Plant the onion seedlings at a depth of 2 inches and cover them with soil. Add water to the soil to hydrate it.

Place the receptacle in a sunny location on your balcony, kitchen window, or terrace. It must receive a minimum of 6-7 hours of sunlight per day. If it is winter or cloudy outside, artificial plant lighting can be arranged.

If the soil is desiccated, check it daily and water accordingly. Remember that the soil should stay hydrated without becoming waterlogged. Simply press the subsoil to determine if it needs water. Depending on the atmospheric conditions, water needs would vary. In frigid climates or during the winter, 2 inches of water per week is sufficient, whereas in warmer climates or during the summer, this amount will increase.

When the seedlings reach a height of 3 inches, they can be harvested. You may also allow the bulb additional time to mature and be harvested. The harvest will take approximately four to five months.

From seedlings

It would be ideal if you chose a container with partitions and drainage openings. It may be 6 inches deep and of average width.

Leave about a half-inch of space between each cell of this container and the potting soil. Only at this stage can a nitrogen-rich fertiliser be applied to the soil.

Purchase onion plant seeds and position them atop the loam in each individual cell. Choose two to three seedlings per cell and then lightly cover them with earth.

Slightly saturate the soil so that the seeds can germinate in a favourable environment.

Place the container in a location that receives 6 to 8 hours of sunlight per day.

Whenever you observe that the soil has dried out, water it. If the weather is excessively warm or during the summer, this plant will need 3 inches of water per week.

When the seedlings reach 3 inches in height, you can harvest them or transplant them to a larger container or outdoor garden. This replanting will result in larger onions.

How to maintain onion plants

Onions are one of the easiest vegetables to cultivate. You can cultivate them indoors in decorative containers and use them for culinary purposes. Here are some guidelines for maintaining the health of your onion plants: –

Sunlight

Onions flourish in direct sunlight. They must receive at least 6 to 8 hours of direct sunlight daily. They never fatigue of spending time outdoors.

Location

The optimal location for onion plants is a location that receives at least eight hours of sunlight per day.

Soil

Onions would thrive best in a soil that is porous and sandy. Add sand to soil that is abundant in organic matter and well-drained in order to grow scallions. The optimal pH range for soil is between 6.0 and 7.0.

Water

Onions require frequent hydration to promote bulb enlargement. Provide one inch of water weekly. However, avoid overwatering the bulbs or allowing them to remain in soil that is too moist, as this may cause bulb decay. To retain soil moisture, apply a thin layer of mulch.

Temperature

The optimal onion vegetative temperature ranges between 13 and 24 degrees Celsius. The optimal temperature range for seedling growth is between 16 and 25 degrees Celsius.

Fertilizer

Onions are moderately voracious consumers. Fertilise them every few weeks with a high-nitrogen fertiliser to stimulate leaf growth, which will result in large bulbs. As soon as the soil splits around the bulb, you will know that the growth cycle for the plant’s foliage has ended, and you can cease fertilising the plant.

In all of our kitchens, onions are used to enhance flavour. When you cultivate this root vegetable in your garden, you can rest assured that it does not contain any chemical fertilisers or pesticides. Moreover, it is simple to cultivate. Try your hand at horticulture and cultivate some delicious onions.
