Growing Scallions in Zone 6B

Scallions (green onions) are one of the most versatile kitchen garden staples — quick, productive, and harvestable at any size.

Zone 6B has a moderate growing season. Most crops do well here with proper timing around frost dates.

Top Growing Tips

• Succession-sow every 2-3 weeks for continuous supply
• Harvest when tops are 6-8 inches tall and bulb is pencil-thick
• Cut above the soil line to regrow multiple harvests
• Grow in containers on a porch or windowsill for year-round supply
• Interplant with carrots — scallions repel carrot fly

Companion Planting

Good companions: carrots, tomatoes, peppers

Avoid planting near: beans, peas (onions inhibit legume nitrogen fixation)

Harvest Timeline

50-70 days from seed; harvest anytime after tops reach 6 inches
