Onion Growing Stages – So Simple Even Your Kids Can Do It

onion-growing-stagesWe are mentioning some names who can turn this article legit. Nick Sanchez. Is he not legit? Ok, Dr Michael. Does this article now seem legit? After all, both these guys are from the University of Florida Extension office. And the title referred to them being all-knowing experts in their field…which is onion growing. I know, I’m surprised too. But once you read on, you’ll see that what they share with you goes far beyond everything you’ve ever heard or known about onion growing before.

Onion Growing Stages In 2022 (And Why You Should Pay Attention)

Onions are one of the most popular vegetables and one of the easiest to grow. You can grow your onions, onion growing stages are from seed or by planting sets (small onions). Onions are grown in most parts of Australia, but they do require a long growing season, so they are usually planted in autumn or winter.

Onion plants grow quickly, and they need a lot of nutrients to do this. So, you must have well-drained soil with plenty of organic matter mixed in before you plant your onions. They also like plenty of water, so make sure you don’t let them dry out between watering.

How to follow onion growing stages

  •       If you want to grow your onion plants from seed, sow them about 10cm apart in rows about 25cm apart.
  •       Water well after sowing and keep the soil moist until the seeds germinate (usually takes 3-4 weeks).
  •       When the seedlings reach about 10cm high thin out some of them so that there are only two or three per space.
  •       If possible, leave them to grow on until about 15cm tall before transplanting into their final position where they will be harvested later in summer or autumn.

Allium cepa

Allium cepa is a plant species. Its edible bulb, from which the onion is derived, has been used as a vegetable and spice for thousands of years. It is a bulb-shaped plant, with white, yellow or red leaves and a strong smell. Onions are harvested by pulling them up from the ground, and dry onions can be stored for months.

Onion is used as the main spice in every food. It is the second most widely cultivated vegetable crop after potatoes and has been selectively bred for its increased yield and disease resistance.


Onion can also be dehydrated and used as powder or flakes. Onion has some health benefits when eaten raw or cooked. It helps with digestion, relieves coughs, reduces blood pressure, and prevents cancer cells from growing.

Onion is a vegetable used as a main spice in every food. It can be consumed raw or cooked. Onion has a lot of health benefits like it reduces the risk of heart diseases and stroke and lowers cholesterol levels and blood pressure.

Onion is rich in vitamin C, B6, B9, and K and minerals like manganese and selenium. The sulphur compounds present in onions help in fighting against cancer cells and help to prevent cancer cell formation.

Onion is a good source of fibre which helps to keep your digestive system healthy. Onions are also good for lowering blood sugar levels which makes them beneficial for people with diabetes type 2.

Onion growing in unknown stages

Onion growing in unknown stages

The onion plant goes through several stages before it becomes an edible vegetable:

Prepare the Soil Stage:

Prepare your garden bed for planting by mixing compost into the soil to improve fertility and drainage. Till up the soil with a rototiller or spade as needed to loosen it up for planting. Add fertiliser according to package directions if desired, but don’t add fertiliser until after all danger of frost has passed so it doesn’t burn your young plants’ roots.

Seed germination –

Onion seeds require light to germinate, so they must be planted shallowly (1/4 inch deep) and covered lightly with soil. A good tip is to wet the seedbed before planting your seeds so that they do not dry out before germination begins. It takes about 10 days for onions to germinate and grow small roots at the top of the seedling.

Growing stage:

Growing stage

The plant grows further upwards with wider leaves than in the germinating stage. You can see a white shoot coming out of the base of each leaf which will form an onion bulb later as it grows up further along with its roots reaching deeper into the soil for water and nutrients needed for growth.

Seeding Stage:

The process of planting onion sets begins in the fall, before the soil freezes. You can also start seeds indoors in February or March and transplant them outdoors once temperatures have warmed up.

Transplanting Stage:

Transplanting is necessary when planting onion seeds directly outdoors because they need to be in the ground by May 1 in most areas of the United States. If you are planting transplants, it’s best to do so in late March or early April so they have time to become established before their first hard frost comes along in fall.

Growing Stage:

The growing stage consists of several tasks, including weeding, watering, and fertilising as needed during dry spells or droughts (or both). Other care includes thinning out plants as they grow larger, so they don’t compete for resources such as water and nutrients from the soil around them; thinning involves pulling.

Vegetative Stage:

The onion is a root vegetable, and all the growth occurs underground. The first leaves to emerge are called seed leaves, which are small and round. As the plant matures, it develops a tall stem with alternating leaves on either side. These leaves are also referred to as hollow sheaths or scales. They stay green for about one month during which time they produce food for the plant’s growth. The bulbs grow underneath the scales and each bulb has its stem that grows from below ground level up into the air until it reaches its full height of about 18 inches (45 cm). The bulb itself is composed of many layers that form concentric rings around the centre, known as the neck.

Reproductive Stage:

When an onion plant reaches maturity at about three months old, it produces flowers that develop into seeds within pods called siliques or umbels. These siliques are usually greenish-brown in colour and contain many seeds inside them which will eventually be dispersed by wind or water currents once they mature into fruit form.

 Emergence Stage:

When your onion seedlings first appear above ground, they will look like little round balls on stalks called scapes (unlike other seedlings which may have left). This stage lasts until the onion tops are less than 1 inch tall and just starting to grow their first leaves.

Bulb Formation Stage:

When an onion seed germinates and starts forming a bulb, it is called the bulb formation stage. In this stage, the leaves of the plant grow rapidly but do not form any branches or leaves yet. The plant grows 1-2 inches each day until the bulb formation begins around 7 days after sowing seeds.

 Maturation Stage:

This stage lasts 5 to 6 weeks when the onion bulb matures as it stores energy for seed production in case it does not receive enough sunlight during the winter months. The plant also forms roots and feeder roots around its base to absorb nutrients from the soil.

Harvesting Onion:

This is the final stage where you harvest your onions by digging them up with a shovel or spade before they flower and produce seeds which will make them less tasty if left on the ground too long after harvesting.

Final words 

Onions are a versatile vegetable that can be used in many dishes. This article provides a step-by-step guide to the growth stages of onions. By understanding the different stages of onion growth, gardeners can better care for their plants and ensure a successful harvest.
