Growing Tips
- Green onions are ready in 50–65 days — one of the quickest edible crops.
- Regrow kitchen scallion roots in water on the windowsill — they'll sprout in days.
- Plant densely — sow 1 inch apart without thinning for a continuous cut-and-come-again crop.
- Harvest by pulling whole plants or snipping tops, leaving 1 inch to regrow.
- Succession sow every 3 weeks for year-round supply in mild climates.
Common Mistakes
- Waiting too long to harvest — green onions become tough and pungent when large.
- Planting near beans or peas — alliums inhibit legume growth.
- Deep planting — seeds only need 0.5 inch depth.
- Not succession planting — one sowing gives a short harvest window.
Companion Planting
Companion planting improves growth, deters pests, and makes better use of garden space.
