When to Plant Scallions in Florida (2026 Guide)
Scallions are a versatile and productive crop that can thrive in Florida's unique climate. With warmer temperatures and a generally extended growing season, many gardeners in Florida can benefit from planting scallions. By understanding your specific USDA hardiness zone, you’ll be able to determine the best times for planting and harvesting this delicious green vegetable.
In Florida, the timing of frost dates significantly affects when you should start your scallion seeds. For those in Zone 8b–9a, the median last spring frost is January 30. This means that scallions can be planted as early as mid-February, allowing ample growth before the heat of summer sets in. Meanwhile, those in Zone 7b–8a enjoy a longer frost-free season, with their last frost occurring on March 4.
Properly timing your scallion planting is essential for maximizing yield. Scallions thrive in cool conditions and can be planted successively to ensure a continuous harvest through the warmer months. For example, in the highest zones like Fort Myers, where the frost-free season is just 12 days, careful planning is key to successful scallion cultivation.

Common Mistakes Growing Scallions in Florida
- Many Florida gardeners underestimate the importance of timing and often plant too late, especially in the warmer zones. Scallions perform best if sown early enough to avoid the peak summer heat, which can hinder growth.
- A common mistake is planting scallions in dense clay soil without proper amendments. Florida's clay can retain too much moisture, leading to root rot. Always ensure good drainage for success with scallions.
- Florida's humidity can lead to disease pressures when scallions are overwatered. Many gardeners often water too frequently, causing fungal issues. It's important to only water when the soil feels dry to the touch.
- Starting scallions indoors in Florida without adequate light can result in weak, leggy plants. Many gardeners overlook the need for good artificial lighting during the winter months when natural light is scarce.
- Some gardeners in Florida mistakenly believe that scallions can withstand any frost. While they tolerate light frost, hard freezes can damage tender greens, so be sure to check local forecasts during late winter.
Frequently Asked Questions
Can I plant scallions in May?
While you technically can plant scallions in May, they may struggle in the higher temperatures of summer. It's best to plant them earlier in the spring to ensure healthy growth before the heat kicks in.
What should I do if my area is prone to late frosts?
If you're in a cold pocket of Florida, consider using row covers to protect your scallions during unexpected frost in March. This extra layer can safeguard your plants and extend your harvesting season.
How can I ensure consistent moisture for my scallions?
To keep scallions well-watered, use mulch to retain moisture in the soil and set up a regular watering schedule. Ensuring even moisture will help prevent issues related to Florida's fluctuating humidity.
What varieties of scallions grow best in Florida?
Look for heat-tolerant scallion varieties that are known to thrive in warmer climates. Varieties like 'Evergreen' and 'Japanese Bunching' perform well across Florida's diverse growing conditions.
When is the best time to harvest scallions?
