An apartment won’t offer you the same facilities as a house with garden, but it’s not impossible to create your own green corner, where you can easily plant some fresh veggies. So, learn how to grow onions in pots. At least this is my solution to eat some organic vegetables, and onion is an important vegetable and also a great health remedy.
1. Potted onions: selecting the pots
Growing onion in pots doesn’t differ much from the one in the garden, but it comes with an essential distinction: the pots. They should be large to allow you growing more onions on the inside of a single pot.
Depending on the space you have, choose the pots to measure – wide and deep. Whatever your choice, it’s important to make sure that each onion will have about 7 cm of earth for itself.
2. Onions in pots: seeds or saplings?
Growing onions in pots, starting with seeds, is the cheapest option. However, given its growing time, it would be ideal to choose seed growing.
If you have decided to grow onion from seeds, make sure they are planted in the soil with 2-3 months before the last frost. Place the seeds at a depth of about 1-2 cm and keep the pots inside the house until the temperatures are increasing.
In regard for seedlings, they should be placed on the balcony only when the outside temperatures exceed 50 degrees Fahrenheit. Plant them in stacked pots at a depth of 5 cm and leave a distance of about 7-8 cm.
Whichever method you prefer, make sure that future onions have a nutrient-rich soil, improved with compost, and good drainage.
If you plan to arrange a variety of vegetables on the balcony, learn that onions can be grown with confidence alongside other tasty vegetables such as beets, carrots, lettuce or cabbage.
3. Onions in pots: vegetable care
Onions, whether planted in the garden or in pots, need plenty of light – more precisely, at least 6 hours of direct sunlight on a daily basis. Move their position on the balcony, if necessary, so as to provide them with the necessary light.
Onions also need a relatively large amount of water. Whenever the land at the surface of the pots is dry, it means it’s time to wipe them again. In the middle of the summer, during heat, you may have to wipe them once every 3 days. Avoid, however, excess moisture, which will cause the rotting of the onions.
4. Onion in pots: how to get rid of pests
If you notice the presence of white spots on the onion leaves, you may experience trips, Thysanoptera pests. To avoid any damage, remove them with organic insecticide as soon as you see them.
