What Are Onion Bulbs?
The bulbs of onions are food-grade and develop beneath the soil of the plant of onions. They are made up of fleshy and altered leaves. They are rich in nutrients that allow the onion plant to thrive in the toughest conditions. The bulbs are usually circular or slightly oval but can vary in size depending on the variety. When harvested, onions are taken from their leaves and roots as their unique layer design is apparent. Each layer comprises thick, papery skins shielding the fleshy, edible part.
Onion bulbs can be grown with seed sets (small onion sets that are not mature) and even transplants. These techniques result in different processes of growth and durations, each of which has its own benefits and drawbacks. By how onions are harvested, they may appear in various colours, including red, white or yellow. The colour of onions can be correlated to the flavour. Red onions typically have a sweeter, less bitter taste when eaten raw, and yellow onions are more pungent and strong when cooked.
Regarding classification, onion species are divided into two groups according to the quantity of sunlight needed for bulb growth: onions that are long-day and shorter-day varieties. The distinction between these two types has an important effect on the growing of their crops.
- Long-Day Onions: Long-Day onions require longer summer days to form bulbs. They usually grow in northern Europe, where summer is longer.
- Short-day Onions: Short-day onions thrive in warm climates with fewer daylight hours, so they are ideal for regions near the Equator.
- Intermediate-day onions can be classified into two groups and modified to various circumstances.
Understanding the distinctions between the varieties is vital for successful onion planting, as planting the correct variety of onions in your area will result in the highest growth and bulb production.

- Short-Day Onions: These varieties flourish in places with fewer sunlight hours. Different varieties like ‘TexasSupersweet and Vidalia can be found in warmer environments.
- Intermediate Day Onions: Intermediate Day Onions adjust to moderate temperature. Candy and “Red Burgundy” are suitable for gardeners in places exposed to sunlight.
Also, be aware of the characteristics of the onion’s flavour. For instance, yellow onions are commonly utilized due to their capacity to be cooked with. Likewise, red onions are favoured due to their less acidic flavour and beautiful colour when consumed fresh.
Preparing the Soil
Onions thrive in loose, fertile soils that drain easily. They require a pH range of 6.0 to 7.0 for maximum development. Therefore, it is essential to assess your soil’s pH before making any needed adjustments. You can alter the soil with compost organic matter, manure, or other well-rotted material to improve fertility and supply a constant supply of nutrients.
Before planting in the garden, you must reduce the soil’s size to 4-6 inches to ensure healthy root growth. Onions do not flourish when planted within the compressed soil, so using a herb tiller or garden fork to cut the soil will aid their development. The location should be surrounded by plenty of sunshine, which is vital because onions require at minimum 6-8 hours daily of sun to grow properly nourished bulbs.
Planting Onion Bulbs
Onions are planted in three ways: seed sets, transplants, or sets. Each method has its advantages and drawbacks. Your choice heavily depends on your ability to handle time and how much knowledge you’ve gained.
- From Seed: The process of starting the onion seeds lasts longer. However, it provides a greater variety of options. Plant onion seeds indoors between 8 and 10 weeks before the last frost. Move the plants to outside space once they have reached an average height of about 4-6 inches and temperatures have increased.
- From Sets: Sets of Onion They are small, non-ripe onions placed directly into the soil. Newbies often favour them as they’re easy to work with and produce faster outcomes.
- From Transplants: The Transplants could be fresh onions purchased from nursery stores or gardening centres. They are an excellent choice for those who wish for a longer harvest period and require less effort at first.

Watering and Fertilizing
Water is among the key aspects of growing onions. Onions require continuous moisture, particularly when dry. However, be cautious with excessive drinking as it may cause root rot and fungal infections. To ensure that your soil remains wet, you should keep the onions hydrated regularly; however, allow the soil’s top layer to dry between waterings.
Fertilizing onions could aid in increasing their growth. Utilize an appropriate fertilizer or organic compost to improve soil nutrients; at first, use an organic fertilizer with high nitrogen levels to promote leaf development before switching to one containing more phosphorous or potassium for roots and bulb growth.
Thinning and Harvesting
Thinning onions is crucial to prevent overloading and to give each bulb the room to develop. They should be cut down to 4-6 inches. Get rid of the weaker ones and leave the more robust ones for the growth to continue.
These onions will be ready for pick when the tops of the greens begin to change colour before they fall over. If this occurs, lift the bulbs carefully off the soil using a garden fork or shovel to avoid damaging them. When onions are picked, they need to be dried and cured. It is accomplished by placing bulbs in a dry and warm place for about seven days. The process of curing allows the skins of the onion to dry and harden, which extends the shelf life of the onions the shelf.
