Onions take approximately 100-175 days to grow before reaching full maturity for harvesting. Timing can vary based on the onion variety and growing conditions.
The length of time for onions to grow before harvest may range from 3 to 6 months, depending on the specific type of onion and environmental factors. When it comes to growing onions, the length of time they take to mature before being ready for harvest can vary.
Generally, onions require around 100 to 175 days to grow before they are ready for harvesting. However, this duration may differ depending on the onion variety and environmental factors such as temperature and soil conditions. The process of monitoring and determining the ideal time for harvesting onions is crucial to ensure their quality and flavor. Understanding the factors influencing the growth period of onions can help gardeners plan and manage their harvest effectively.

Stages Of Onion Growth
Onion growth stages vary, taking around 3-4 months before the roots begin to show signs of bulbing. Harvest onions when the foliage turns yellow and falls over, letting them cure for a couple of weeks before storage. Timing is crucial for optimal size and flavor.
Seeding | Onions are initially planted from seeds, starting the growth cycle. |
Bulb Formation | Over time, onions develop bulbs under the soil, a crucial stage before harvest. |
Maturity | When onions reach full maturity, the foliage starts to turn yellow, indicating they are ready to be harvested. |

Factors Affecting Onion Growth
Factors affecting onion growth include soil conditions, watering needs, and climate considerations. The quality and composition of the soil can greatly impact the growth of onions. Onions thrive in well-draining soil that is rich in organic matter. Adequate moisture is also important for onion growth, as they require regular watering, especially during dry periods. The climate plays a crucial role in onion growth as well. Onions prefer cooler temperatures, ideally ranging from 55 to 75 degrees Fahrenheit. They can tolerate some heat, but extreme heat can hinder growth. On the other hand, freezing temperatures can also negatively impact onion growth. It is important to consider these factors when growing and caring for onions to ensure a successful harvest.
Signs Of Onion Readiness For Harvest
How Long Do Onions Grow before Harvest: Onions are ready for harvest when the foliage starts yellowing and toppling over. Yellowing of foliage indicates that the plant has stopped growing, while the toppling over of leaves shows that the bulbs have reached maturity. Once these signs appear, it’s time to prepare for harvesting. The ideal time to harvest onions is when half of the foliage has withered. Once harvested, the bulbs need to be cured to ensure they can be stored for a longer duration without rotting. Curing involves the process of drying the onions in a warm, well-ventilated area until the necks become tight and the outer layers are dry. This prepares the onions for storage and consumption.
Proper Harvesting Techniques
When it comes to harvesting onions, proper techniques are essential for a successful yield. Loosening the soil around the onions is crucial to allow for easy removal without damaging the bulbs. Gently removing the onions from the ground minimizes bruising and ensures they remain intact for storage. Once harvested, the curing process is vital for drying the onions and preparing them for long-term storage. This process helps to enhance their flavor and prolong shelf life. All these steps are necessary for a bountiful onion harvest.
Storage And Preservation
Drying Techniques:
One common method of preserving onions is through drying. Drying onions helps remove excess moisture, allowing them to last longer in storage. To dry onions, you can use either a traditional air-drying method or a food dehydrator. The traditional method involves tying onions in bundles and hanging them upside down in a warm, well-ventilated area. This allows the onions to slowly dry out over time.
Ideal Storage Conditions:
For onions to remain fresh for an extended period, proper storage conditions are essential. Onions should be stored in a cool, dark, and well-ventilated space. The temperature should ideally be between 32 and 40 degrees Fahrenheit. Avoid storing onions near potatoes, as the gases emitted by potatoes can cause onions to spoil more quickly. Additionally, onions should be kept away from light, which can trigger sprouting. Properly stored onions can last up to several months.

Common Challenges In Onion Harvesting
Harvesting onions poses common challenges, as the growing period ranges from 90 to 120 days. Timing the harvest is crucial, as onions mature when their tops turn yellow and begin to fall over. Failing to harvest at the right time can lead to over-maturation and spoilage.
Pests and Diseases: Onions are susceptible to pests such as thrips and onion maggots. Diseases like downy mildew and botrytis can also affect onion crops. |
Improper Curing: Curing is crucial for onion storage. Improper curing can lead to mold growth, affecting the quality of harvested onions. |
Frequently Asked Questions For How Long Do Onions Grow Before Harvest
How Do I Know When My Onions Are Ready To Harvest?

Harvest when the weather is dry and sunny, and store them in a cool, dry place.
How Long Until Onions Are Fully Grown?
Onions typically take 90 to 120 days to reach full maturity before they are ready for harvest.
How Long Can Onions Stay In The Ground?
Onions can stay in the ground for two to four weeks after they fall over.
How Long After Onions Fall Over Do You Harvest?
Onions can be harvested after they fall over. Typically, this happens around 100-150 days after planting.
Conclusion
The length of time it takes for onions to grow before harvest depends on various factors such as onion variety, growing conditions, and desired size. On average, onions can take anywhere from 80 to 120 days to reach maturity. It is important to monitor the growth and development of the onion plants, looking for key signs like bulb formation and the drying of the tops, to determine when they are ready for harvest.
Properly curing and storing the harvested onions will ensure their longevity and quality. Happy growing and harvesting!
