When to Plant Scallions in Alabama (2026 Guide)
Planting scallions in Alabama can be a rewarding endeavor for gardeners looking to maximize their harvests. With the growing season in various regions, especially in cities like Birmingham where the median last spring frost is April 3, it is important to plan your planting schedule carefully. Scallions are versatile and can be planted in succession every few weeks, allowing for a continual supply from spring to fall.
In Alabama, the climate can be a bit unpredictable, especially with the median first fall frost occurring as late as November 25 in areas like Mobile. This extended frost-free season means that gardeners have ample opportunity to cultivate scallions, but timing is crucial. Understanding the frost dates in your area will help ensure a bountiful crop from these non-bulbing onions, which thrive in cooler weather and can tolerate a light frost.
Whether you're in the cooler zones of north Alabama or the warmer coastal regions, scallions can be a fantastic addition to your garden. They grow quickly, typically ready for harvest in about 60–70 days. With proper planning, especially around the last frost dates, you can enjoy a fresh supply of green onions throughout the growing season.

Common Mistakes Growing Scallions in Alabama
- Many Alabama gardeners underestimate the impact of humidity and soil moisture on scallion growth. It's crucial to monitor watering as over-saturation can lead to root rot, while under-watering can stunt growth during hot spells.
- New gardeners in Alabama often plant scallions too late. Given the median last frost dates, it is vital to start them indoors in time to transplant, particularly in areas like Birmingham where spring arrives later.
- Scallions are quite tolerant to frost, but gardeners frequently harvest them too late in the fall. Harvesting before the first fall frost on October 28 ensures quality and flavor.
- Not taking into account Alabama’s coastal fog can hinder growth, especially in areas like Mobile. This can create a cooler microclimate which may slow down growth rates during critical planting times.
- Another mistake is failing to utilize succession planting. Many gardeners in Alabama plant one large batch, which leads to a glut. Instead, plant every 3–4 weeks to enjoy continuous scallion harvests throughout the season.
Frequently Asked Questions
What if I'm in a cold pocket of Alabama?
In colder pockets, such as mountainous areas, start your indoor seedlings a week or two earlier. Be cautious about late frosts even into May, and protect any outdoor plants with row covers if temperatures drop unexpectedly.
Can I still plant scallions in May?
While it's best to plant scallions earlier, you can still plant in May, especially in warmer areas like Mobile. Just ensure you plan for a shorter harvest period before the fall frost arrives.
What should I do if frost threatens my scallions?
If frost is expected, cover your scallions with row covers or blankets to protect them. If they get frost-damaged, harvest immediately and use them, as they're still edible when cooked, although their texture may be affected.
How much sun do scallions need?
Scallions thrive in full sun, meaning at least 6 hours of direct sunlight per day. However, they can tolerate some partial shade, especially during the hottest months in Alabama, to prevent bolting.
Do scallions grow well in containers?
Yes, scallions are excellent for container gardening! You can use pots of at least 6 inches in depth, allowing you to grow a good number of scallions in a small space while keeping them easily accessible.
