Garlic planting guide

When to plant garlic

Choose a local fall plan instead of one U.S.-wide month. Minnesota Extension uses 1–2 weeks after the first killing frost; Illinois Extension uses 4–6 weeks before the ground freezes. Those are different climate cues, so use an Extension source that covers your state before picking a day.

Start with your local cold milestone Use a state guide for a date range, then check that the bed is workable.

Why there is no single national date

The official examples use different weather and soil milestones. Do not average them into a date that appears precise for every state.

Choose your local route

These state pages give a local starting point. They are not substitutes for an Extension source in a state Garden Tempo does not yet support.

Plant individual cloves

Garlic is planted from cloves, not as an intact bulb. Separate the cloves when you are ready to plant, keep the variety label, and follow the depth and spacing instructions in the local Extension guide you selected.

If the fall window has passed

Do not turn this national guide into a promise that every garden has the same spring option. Keep the planting stock label, then compare current state Extension advice with the conditions in your bed before changing the plan.
