Zone 1a Planting Schedule

Last spring frost: Jun 15th
First fall frost: Jul 15th
Growing season: 30 days

Action Plan: May in Zone 1a

Expert Note

May in Zone 1a is still short-season; keep soil evenly moist and warm before sowing. Watch for flea beetles and cutworms on tender greens and garlic shoots; use row cover early and remove once plants are established.

Seed & Soil

Direct sow and transplant for quick, high-value results: get Kettle River Giant and King Richard into the ground while conditions are stable, and plant Siberian Garlic for reliable harvest later. If nights are cool, use row cover to protect emerging seedlings and improve early growth.
