Growing onions start as small green shoots that develop into bulbs, which mature into full-sized onions. The bulbs are ready for harvesting when they grow big and the tops turn yellow and start to droop.
Onions go through different stages of development, from sprouting as small greens to reaching full bulb potential. As they mature, the expanding bulbs start pushing the dirt aside, and about two-thirds of the onion should be visible above the surface.
Understanding these growth stages and signs helps in knowing when onions are ready for harvest. By recognizing the appearance and growth patterns of onions, it’s possible to determine the ideal time for harvesting. This comprehensive understanding contributes to successful onion cultivation and a bountiful harvest.

What Do Growing Onions Look Like When They Are Done
Growing onions are mature when the bulbs are large, and the green tops turn yellow and fall over. As the bulb expands, the soil may crack, with two-thirds of it visible above the surface. Onion sets resemble small bulbs sold in gardening stores, growing into full-size bulbs with maturity.
When growing onions, let them mature into full-sized bulbs. |
Ready for harvest when bulbs are large, tops turn yellow, and start falling over. |
Signs Of Onion Bulbing
When onions start bulbing, the ground cracks as the bulbs grow and push dirt aside. Mature onions are ready for harvest when tops turn yellow and fall over. Let the bulbs reach full size before harvesting for optimal results.
Once bulbing begins, the ground will start cracking around the onion |
About two-thirds of the bulb should be above the surface |
What Onions Look Like When First Sprouting
When onions first start sprouting, they appear as tiny little greens, resembling micro-scallions. These micro-scallions emerge from the seed and are able to take up light because they are the leaf. There is no need to take any drastic measures at this stage, as the plants will continue to grow.
In order to grow full-sized onion bulbs, it is important to let the onions mature. The bulbs are ready to harvest when they are big and the tops start turning yellow and falling over. This indicates that the onions have reached their full potential.
There are various methods to grow onions, including starting from seeds or using onion sets (small bulbs). The sets develop into full-size bulbs over time. It takes approximately 100-120 days for onions to fully grow and mature.
If you want to store onions after harvesting, it is recommended to cure them for a few weeks in a well-ventilated area. Proper storage techniques will help extend their shelf life.

How To Grow Onions From Sowing To Harvest
Choosing a variety: Before sowing onions, select a suitable variety based on your location and the time of year.
Soil requirements: Onions thrive in well-drained, fertile soil with a pH level of 6 to 7.5.
Sowing onion seeds: Plant seeds ¼ inch deep, and space them 1 inch apart in rows.
Using row cover or fleece: Cover the seedbeds with row cover or fleece to protect the young plants from pests.
Planting sets: Place onion sets into the soil, leaving the tip exposed, and space them 4 to 6 inches apart.
Watering and weeding onions: Keep the soil consistently moist and free of weeds throughout the growing season.
Harvesting onions: Harvest onions when the tops turn yellow and begin to fall over, then dry them for storage.
How to store onions: Cure harvested onions in a warm, well-ventilated area for 2-3 weeks before storing them in a cool, dry place.
Different Methods Of Growing Onions
Sure! Here is your response in HTML format:Growing onions from seeds can be a cost-effective approach. Starting onions from seeds allows for a wide variety of choices and ensures a healthy start.

Tips For Successful Onion Growth
When it comes to growing onions, there are key factors to consider for successful growth. First and foremost, soil preparation is crucial. Onions thrive in well-draining soil with good fertility. Ensure the soil is loose and free from rocks, and adding organic matter can improve fertility.
Next, planting requirements play a vital role. Onions can be grown from seeds or sets. Seeds offer more variety options, while sets are easier for beginners. Planting depth should be about 1 inch, and spacing between plants is typically 4-6 inches.
Weeding is an essential task to keep the onion bed clear from competition. Regularly remove weeds to prevent them from stealing nutrients and water from the onions.
To prevent bolting, which is premature flowering, provide onions with consistent moisture throughout their growth. Bolting can be triggered by temperature fluctuations or stress due to lack of water, so ensure onions receive adequate water.
Curing and storing onions is necessary to prolong their shelf life. Once the tops begin to turn yellow and fall over, it’s a sign that the onions are ready to be harvested. Cure them in a warm, dry, and well-ventilated area for about two weeks before storing them in a cool and dark place.
