When to Plant Onions in Zone 6

Onions are a cool-season crop that can be grown in most parts of the United States. However, the best time to plant onions in Zone 6 depends on the variety you choose.

Spring planting

Spring-planted onions are typically started indoors in early spring and then transplanted outdoors after the last frost date. This method allows you to get a head start on the growing season and enjoy fresh onions earlier in the year.

When starting onions indoors, sow seeds in peat pots or seed trays about 6 weeks before the last frost date. Keep the seedlings warm and well-watered until they are ready to be transplanted.

Once the weather has warmed up and the risk of frost has passed, you can transplant the seedlings outdoors. Space the plants 4 to 6 inches apart in rows that are 12 to 18 inches apart.

Fall planting

Fall-planted onions are typically planted in late summer or early fall. This method allows the onions to mature and grow during the cool weather of fall and winter. Fall-planted onions will be ready to harvest in early spring.

When planting onions in the fall, choose a spot that gets full sun and has well-drained soil. Dig a trench about 2 inches deep and 12 inches wide. Sow the seeds about 1 inch apart and cover them with soil. Water the seeds well and keep the soil moist until the seedlings emerge.

Overwintering onions

If you live in a climate with cold winters, you may need to overwinter your onions. To do this, simply leave the onions in the ground and cover them with a thick layer of mulch. The mulch will help to protect the onions from the cold weather and keep them from freezing.

In the spring, remove the mulch and wait for the onions to start growing again. Once the onions are about 2 inches tall, you can harvest them.
