Plant onions on the roof or porch

The onion price is multiplying several times higher than other times. It is a little daunting to find satisfying Bengali cuisine without this essential ingredient in cooking. This onion price has to be carried out daily by buying onions at a price much lower than usual. Many middle-class families have given up onion feeding. What happens when onions are grown using the roof or porch of your home right now? Demand for your family onion may not be satisfied by cultivating on the porch, but you can join in the silent protest by buying the onion in the market even if the commodity prices are modest.

Onions are one of the most popular vegetables for growing in the roof of the house or on the balcony and one of the first crops of spring. Onions can be cultivated as a versatile crop in winter and stored.

Onions are a very popular vegetable used in both raw and cooked conditions. Here are some important tips for cultivating onions or allium family vegetables:

  • All the vegetables in the Allium family require full sun.
  • Allium cultivars require good drainage soils. Onions are best grown on sandy soil. So for good yield, add organic material to the soil and compost before planting.
  • Loosen the soil for up to 5 inches to allow plenty of room for water and air to flow and help the roots make their way through the soil.
  • Alloyed vegetables require more nitrogen and phosphorus. So add blood mill or cotton mill and phosphorus bone powder for nitrogen.
  • Alliums do not get good if they get too much water. By drip irrigation, it is possible to get the best results by irrigating the water.
  • Alligator vegetables should be avoided in the same place every year. Alliums are at risk of soil-borne diseases, so they must be cultivated at least two seasons. This is not difficult to do in a small garden, as alliums do not require a lot of open space.

  • There are three ways to plant onions – directly by seed, by seedbed and by sowing. Most likely to grow from seedlings.
  • Most of the four are grown in containers. They should be separated and planted one inch apart.
  • Depending on the length of the day, onions are made of several varieties – long, intermittent and short. This segmentation is based on the amount of daylight.
  • Another thing to consider in onion cultivation is the shelf life of onions. If stored in storage for up to six months, it can last up to six months, while others are much less.
  • When the green leaves of the onion begin to die, the onions should be picked, but not before the onion seeds germinate. The onion is usually better if kept longer – but the onion will continue to harden. As a result, onions will be less. The onion bulbs that are made will not last well and they should be used immediately.
  • After the onion is done, place the onions one layer in the shade, leaving the leaves attached. When the leaves are completely dry, carefully prune the onions.


If you want to make the soil by adding fertilizers or composted organic matter, keep it for several weeks before sowing / planting.


Onions can be planted from seed or scandal (small partially grown onion bulbs). Sets are expensive but they have higher yields than others and require less labor.

If sown from seed, sow at a depth of about 2 cm with a gap of about 5 inches between the seeds. If planted in rows, keep the rows about 3 cm apart.

The soil must be moist before sowing, so check the soil the day before sowing and irrigate it if the soil is dry.

If the onion is planted, plant about 5 cm away. They do not need to loose the soil when cultivated using onion scandal. Dig a small hole for each skunk and place the scandal on the top of the neck. Covering the soil, the tip of the shoulder can only be seen above the ground.

During the cultivation

In our country, onions are mainly cultivated during the rabi and kharif season. Seeds are sown in July-August (Sravan-Vadra) for the cultivation of Kharif season and February-March (Magh-Falgun) for the cultivation of Rabi season.

Soil type

Onions should be cultivated in fertile soil and drainage facilities. Soil and sandy loam soil is good for onion cultivation. The soil should be luge. If your soil is heavy, you can use some organic compost or fertilizer in the soil to keep it moist. Onions are generally suitable for cold climates. If the temperature is high during onion cultivation, then the onion is shaky.

Onions prefer slightly acidic soil – pH 5.5-6.5 suitable for onion growth.

Onion beds should be weeded frequently by weeding.

If cultivated from seed, the onion should be diluted to a height of about 5 cm.

Fertilizer management

Onion beds are used for cow dung, urea, TSP and mop fertilizers. The ratio of urea, TSP and MOP is 1: 2: 5.4. At the time of making the land, half urea and the rest of the fertilizer are mixed in the soil. The remaining urea is applied to the fertilizer 20 days after planting.

Irrigation and weed management

If there is scarcity of water in the land during winter, then it should be irrigated. In the rainy season so that rain water cannot stand, there must be a hole in the tub or bed. The land should be kept weed free. After irrigation, the land should be drained loose. In the case of onion tuber production, the flower buds should be broken as shown.
