Onions are a staple in many dishes and are a great addition to any garden. Knowing how to grow onions in Ohio can be a rewarding experience, but it requires some knowledge and planning. In this blog post, we will discuss how to grow onions in Ohio, from planting to harvesting.
Firstly, it is important to know that there are two types of onions: long-day onions and short-day onions. Long-day onions require 14-16 hours of daylight to form bulbs, while short-day onions require 10-12 hours of daylight. In Ohio, long-day onions are the most suitable type of onion seeds to grow.
To get started, you can either plant onion seeds or onion sets. Onion seeds are usually started indoors 8-10 weeks before the last expected frost date. Onion sets, on the other hand, are small bulbs that have been grown from seeds the previous year. They are usually planted in early spring, a few weeks before the last expected frost date.

The best time to plant onion seeds or sets in Ohio is in early spring, usually in April. The soil temperature should be around 50°F, which is the optimal temperature for onion germination. The seeds or sets should be planted about an inch deep, with a spacing of 4-6 inches between each plant. If planting onion sets, make sure to place them with the pointed end facing up.
Onions prefer well-drained soil that is rich in organic matter. They also require regular watering, especially during the growing season. If you notice that the soil is dry, make sure to water the plants deeply. However, avoid overwatering, as this can lead to rotting.
During the growing season, it is important to keep the weeds under control. Weeds compete with onions for nutrients and water, which can reduce their growth. You can either remove the weeds by hand or use a mulch to suppress their growth.
Onions in Ohio take around 120 days to mature. As the plants grow, they will start to form bulbs. When the tops of the plants start to dry out and fall over, it is a sign that the onions are ready for harvesting. Carefully dig up the onions and allow them to dry in a warm, dry location for a few days. Once the outer layers of the onions are dry, you can remove the roots and tops and store them in a cool, dry place.
It is important to note that Ohio has a relatively short growing season, so it is important to choose the right variety of onions for your area. Some varieties, such as Candy and Copra, are better suited for longer growing seasons. Other varieties, such as Walla Walla and Vidalia, are better suited for shorter growing seasons.
In conclusion, growing onions in Ohio requires some planning and knowledge, but it can be a rewarding experience. Choose the right variety for your area, plant the seeds or sets in early spring, keep the weeds under control, and water regularly. With these tips, you can enjoy a bountiful harvest of fresh, flavorful onions.
