When Do I Harvest Garlic in Ohio?

As you may have already guessed, there are two main factors that determine when you should harvest your Garlic: the physical features of the garlic & weather (time).

Harvest Garlic if They Look Like This!!!


The physical features of garlic are what most gardeners commonly rely on to determine if they are ready to be picked off the plant or not.

In general, you should harvest garlic if they have the following physical features:

  • The leaves of the garlic are tall, long, and dark green in color.
  • The garlic bulb has cloves of white and is about 4 to 6 inches in diameter

Harvest Your Garlic During THIS Time of Year!!!

In general, you should harvest garlic:

  • 240 – 270 days after starting garlic from seed
  • 120 days after planting garlic in your garden

And no matter what, you should ALWAYS harvest your garlic before the first frost of the year. Frost will immediately kill your scallion plant and make your garlic inedible.

For your reference, I have created this table for average frost dates for most major cities in Ohio. If your city is not listed below you can find its Last & First Frost Dates HERE.

It should be noted that you should not overly rely on the first frost of the year. The average first frost of the year is only correct 30% of the time.

Instead, pay close attention to your local weather.

When you know a frost is coming you need to take action.

  • If garlic is in pots, bring them inside
  • If garlic is in the ground, cover them in burlap and hope they survive
  • Pick all garlic.
