When to Plant Garlic in Ohio

Growing Garlic in Ohio: Complete Guide

Garlic (Allium sativum) is fall-planted — it goes in the ground a few weeks before the first fall frost and overwinters for harvest the following summer. Depending on your zone, Ohio gardeners plant between September 25, 2026 (Zone 5b) and October 15, 2026 (Zone 7a).

Because Ohio stretches across 4 USDA hardiness zones (5b, 6a, 6b, 7a), planting windows can shift by as much as two to four weeks from one end of the state to the other. Gardeners in the warmer southern zones can start earlier, while those in cooler northern zones should wait until the zone table above shows their last frost has passed.

With 240 days to maturity, Garlic fits comfortably within Ohio's growing season in most zones. In the warmest parts of the state, a second planting later in the season may be possible.

Garlic requires full sun (6+ hours) and low to moderate moisture. Midwest growing seasons are compressed between late spring frosts and fall cold snaps, so timing transplants precisely pays off.
