When to Plant Onions in Ohio

Introduction

Planting onions in Ohio can be a bit of a challenge due to the state's changing weather patterns. While onions are fairly easy to grow, timing is key. In this article, we will discuss the best time to plant onions in Ohio and the steps you can take to ensure a successful harvest.

Choosing Onion Varieties in Ohio

Onions are classified as either short-day, long-day, or intermediate-day varieties. Short-day onions require 10-12 hours of daylight to bulb properly, while long-day onions require 14-16 hours of daylight. Intermediate-day onions require 12-14 hours of daylight. In Ohio, it is best to plant intermediate to long-day varieties to ensure the onions have enough daylight to bulb properly.

When to Plant Onion Seeds in Ohio

Onion seeds should be planted as soon as the soil can be worked in the spring, typically between mid-March and mid-April in Ohio. This will ensure that the onions have enough time to grow before the heat of summer sets in. Plant your onion seeds in well-draining soil enriched with compost or fertilizer, mixing in a balanced fertilizer at a rate of 2-3 pounds per 100 square feet of garden space.

Planting Onion Sets in Ohio

If you prefer to plant onion sets instead of seeds, it is best to wait until early April in Ohio. Onion sets are small, immature onions that have been grown from seed and then dug up and dried. They are popular with gardeners because they take less time to mature than starting onions from seed. Plant your onion sets about an inch deep, with about 4-6 inches between each set.

Caring for Your Ohio Onion Crop

Onions require regular watering, especially during dry spells. Water them deeply once a week, rather than a little bit every day, to encourage deep root growth. Mulching around your onion plants can help to retain moisture and prevent weeds. Once your onion bulbs have started to form, stop watering to help them dry out and encourage the outer skins to toughen up.

Harvesting Your Ohio Onions

Onions are ready to harvest when the tops start to dry out and fold over. Carefully pull them out of the soil and lay them in the sun to dry for a few days. Once the outer skin is papery and the tops are completely dry, you can store your onions. Cut off the tops and store your onions in a cool, dry place with good air circulation. If properly stored, your Ohio onions will keep for several months.

Conclusion

Knowing when to plant onions in Ohio is the key to a successful onion crop. Plant your onion seeds or sets in the early spring and be sure to care for them properly by watering deeply, mulching, and allowing the bulbs to dry out before harvesting. With a bit of effort, you can enjoy a bountiful onion harvest in Ohio.
