Buying Guide: Key Considerations For Short-Day Onions
Short-day onions bulb when daylight drops to about 10–12 hours. They are often best for southern gardens, warm climates, or regions with mild winters. When choosing, consider:
- Seed vs. sets: Seed collections offer color diversity and longer storage, but require more time to mature. Sets provide quick, reliable bulbs with less wait.
- Climate compatibility: Short-day varieties suit USDA zones 7–9 or warm winters; long-day types perform better in cooler regions.
- Harvest window: Some mixes include bulbing and non-bulbing greens; plan around your desired harvest timing.
- Flavor and usage: Sweet Granex and Red Burgundy are milder and good for raw preparations; Red Creole and similar varietals offer fuller flavor for cooking.
- Storage and handling: Bulbs vary in size and sweetness; ensure proper curing and storage conditions for maximum shelf life.
