When to Plant Scallions in Maryland (2026 Guide)
When planning to plant scallions in Maryland, understanding the local climate and frost dates is essential. For instance, gardeners in Zone 6b, which includes cities like Annapolis and Aberdeen, can expect their last spring frost around April 11. This information significantly impacts when to start your seeds indoors and when to direct sow outdoors.
In contrast, those in Zone 6a, covering areas such as Beltsville and Bowie, will find that their last spring frost is typically on April 18. Knowing this helps ensure that your scallions thrive throughout the growing season, which for many parts of Maryland spans roughly 187 to 201 days of frost-free weather.
Regardless of your specific zone, scallions are forgiving and versatile crops. They can be sown directly into the garden or started indoors if you want to get a jump on the season. Additionally, with their fast 60-70 day growth cycle, scallions can provide a near-constant supply from your garden throughout the spring, summer, and even fall.

Common Mistakes Growing Scallions in Maryland
- Many gardeners in Maryland mistakenly plant scallions too late in the spring, missing out on the best growing conditions. Aim for early sowing to optimize your harvest before summer heat sets in.
- Another common error is failing to recognize the dense growth habit of scallions. Not providing enough spacing can lead to stunted growth and poor yields, especially important in tight Maryland spaces.
- Some gardeners assume scallions can handle extreme heat without damage, leading to disappointments in yield. Maryland summers can be particularly hot, so plan for some shade if temperatures soar.
- Planting all seeds at once instead of staggering them can result in overabundance or gaps in supply. Succession planting every 3-4 weeks is key for optimal harvests throughout the growing season in Maryland.
- Fewer experienced gardeners overlook that scallions can regrow from the base after harvesting. Rather than discarding the roots, take advantage of this by replanting and extending your harvest season.
Frequently Asked Questions
What if I'm in a cold pocket of Maryland?
If you find yourself in a colder microclimate, consider starting your scallion seeds indoors a bit earlier, aiming for the latest indoor start date in your zone. Transplanting outdoors should also be adjusted to maximize your growing window.
Can I still plant scallions in May?
Yes, you can still direct sow or transplant scallions in May, especially if you're in Zone 6b. Just be mindful of the warmer temperatures and ensure consistent moisture for optimal growth.
How can I extend my scallion harvest?
To extend your harvest, practice succession sowing every 3-4 weeks and consider regrowing the bases of harvested scallions. This approach can significantly maximize your yield over the growing season.
What are the best soil conditions for scallions?
Scallions prefer well-draining soil rich in organic matter. If you're gardening in heavier clay soils common in parts of Maryland, amend your soil with compost to enhance drainage and fertility.
Do scallions need full sun?
Scallions thrive best in full sun, requiring at least 6 hours of direct sunlight each day. If your garden is partially shaded, they can still grow, but the yield may be less prolific.
