Are you growing horseradish in Ohio, but don’t know when the best time to harvest them is?

When Do I Harvest Horseradish in Ohio?

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

Harvest Horseradish if They Look Like This!!!

The physical features of horseradish 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 horseradish if they have the following physical features:

  • The leaves of horseradish are long, wide, and light green in color and are at least 6 inches long.
  • The Horseradish vegetable is long, white, and looks like a giant carrot.

Harvest Your Horseradish During THIS Time of Year!!!

In general, you should harvest horseradish:

  • 360 days after starting horseradish seed
  • Immediately after planting horseradish in your garden

And no matter what, you should ALWAYS harvest your horseradish before the first frost of the year. Frost will immediately kill your horseradish plant and make your horseradish 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 horseradish are in pots, bring them inside
  • If horseradish is in the ground, cover them in burlap and hope they survive
  • Pick all horseradish.
