When to Plant Scallions in Arkansas (2026 Guide)

Growing scallions in Arkansas can be a rewarding endeavor, thanks to the state's diverse climate and prolonged growing season. Whether you're in Zone 6b with a median last spring frost of April 7 or Zone 7a with March 29, knowing when to plant will help ensure a prosperous harvest. Scallions, also known as green onions, are hardy crops that can be planted multiple times throughout the year.

These versatile plants thrive in cool weather, but they can also tolerate some heat, making them a suitable option for the warmer seasons. In Arkansas, the frost-free season varies, with Zone 6a experiencing about 186 days and Zone 7a enjoying roughly 221 days. This means there is plenty of time to enjoy a continuous supply of fresh scallions if planted strategically throughout the year.

To maximize your scallion harvest, consider direct sowing every 3–4 weeks. This technique not only yields a fast turnaround, typically within 60–70 days from seed, but it also helps to ensure you have a constant supply. By keeping the gardening calendar in mind and utilizing the unique growing conditions of Arkansas, you can enjoy these crisp and flavorful additions to your meals for months on end.

Common Mistakes Growing Scallions in Arkansas

One common mistake some Arkansas gardeners make is attempting to direct sow scallions too close to the last frost date. Given the median last frost is April 7 in much of the state, it's crucial to wait until after this date for successful germination.
Many Arkansas residents plant scallions in humid conditions without realizing that excessive moisture can lead to diseases such as rot. Ensure your soil drains well to prevent any fungal issues from dampness, especially in spring after rains.
Another mistake is overcrowding scallions during sowing. Scallions need space to grow properly; planting them too close together can result in smaller yields. Aim for around one-inch spacing to ensure they have enough room to flourish.
Some gardeners in Arkansas overlook the benefits of succession planting. Instead of sowing all your seeds at once, try planting every 3–4 weeks to keep a steady supply of scallions. This is especially useful during the warmer months when growing conditions can change rapidly.
Finally, a common misstep is planting scallions in locations that receive full sunlight without considering the heat. While they tolerate heat reasonably well, very high temperatures can stress the plants. Positioning them where they receive some afternoon shade during summer can keep them healthy.
