Onion: A Beginner’s Guide to Growing Onions Indoors

When it comes to vegetables in an outdoor garden, onion is one of the most popular. Its abundance of applications, especially in cooking, is perhaps one of the reasons why it is a favorite for many home gardeners. Fortunately, even if you do not have a large space or yard, you can still plant onion. They will survive even in an indoor environment, as long as you pay attention to proper care and growing conditions.

Onion is a cool-season vegetable that belongs to the genus Allium, which makes it a close relative of leek, garlic, and shallot. According to historical records, onion has been around for more than 7,000 years with initial applications in the field of alternative medicine. The height can be anywhere from 6 to 18 inches. The leaves, meanwhile, are flat and usually bluish or yellowish.

There are three main varieties of onions, with their distinguishing characteristics being the color of their skin or bulb. This impacts not only their external appearance, but also has an effect on their flavor. Out of the three varieties, the most popular is the yellow onion. Its skin is pale gold and has a full flavor, making it ideal for cooking almost anything. Red onion, on the other hand, has a dark color and will be the perfect choice for roasting and grilling, among others. Meanwhile, for white onion, it is best for pasta sauces and salads. When choosing which one to grow, consider how you will use the onion to determine which variety will make the best choice for an indoor garden.

Planting and Growing Conditions

To plant onions indoors, one of the first things that require your attention would be the specific variety of plant. You can choose from yellow, red, or white. The differences have been discussed earlier. Choose a variety with a small or medium size, considering the fact that you will plant them in a container with minimal space available. You also need to choose onion on the basis of their light requirements, although both of which are perfect for indoor growing, especially if you have artificial light. In the case of short-day onions, they require at least ten hours of light and for long-day onion, they need at least 14 hours of light. Consider the place where you live to determine which one is the better choice.

Find a container where you will grow the onion. You need to choose a pot with a large size, which will allow you to plant more onions. This also means that you will enjoy higher yield. It will be better to choose a rectangular pot with a depth of about ten inches. A plastic tub will be a good choice, especially because it is lightweight and cheap. Do not forget to drill holes at the bottom, which will act as the drainage.

When the pot is ready, fill it with your choice of a potting mix. A loamy soil that is well-draining and with neutral pH level will work best for onions. Adding mature compost will also be good, which will help to enrich the nutrients.

Now that the soil is ready, spread seeds on the surface, but make sure that there will be no overcrowding. Growing from seeds, however, is not for people who are impatient. With this, a better alternative is to use onion sets or transplants. This way, you do not have to wait for a long time before your onions will be ready to harvest.
