Buying Guide
- Fall planting readiness: Choose onions labeled as suitable for fall planting or day-neutral varieties that establish roots quickly before winter dormancy.
- Day length adaptation: Some varieties perform best as short-day, long-day, or day-neutral; select based on your latitude for optimal bulb development.
- Storage and flavor: Consider varieties noted for sweet or storage-friendly onions if you want a long shelf life and versatile cooking options.
- GMO status and soil needs: Non-GMO sets are common in home gardens; ensure the soil is well-drained, loose, and enriched with compost for best results.
- Seed vs. sets: Onion sets (bulbs) are quicker to harvest compared to seed-grown onions. For faster autumn-to-spring results, sets are usually preferable.
- Garden scale: Bulk packs like 25+ counts suit larger plots, while smaller mixes are ideal for beginners or container gardens.
- Maintenance: Ensure consistent moisture without over-watering. Mulching can reduce weed pressure and stabilize soil temperature during fall.
- Harvest window: Plan for staggered planting when possible to extend harvest; fall plantings typically mature in late spring to early summer.
- Climate considerations: While many onion sets are versatile, check local climate notes for fall planting viability in your region and adjust timing accordingly.
