Here is the BEST Time to Start Horseradish Seeds in Ohio! (2023)

Do you want to grow Horseradish seeds in Ohio, but don’t know when to start them?

Starting Horseradish seeds is not as easy as it seems.

Here’s why:

  • Horseradish must be consistenly watered, receive at least 8 hours of sunlight a day, & be kept at room temperature of at least 70 degrees Fahrenheit.

So if you don’t consistently water them they won’t germinate. If they aren’t in a room that is at least 70 degrees Fahrenheit they won’t sprout. And if it receives 8 hours of sunlight the plant itself won’t grow.

  • Because Ohio’s growing season is not long enough, horseradish seeds cannot be sowed outside and should only be started indoors.

Because of this, I’m going to teach you the ideal time to start horseradish seeds indoors in Ohio:

When to Start Horseradish Indoors

Depending on the type of horseradish, it takes roughly 28-56 days (4 to 8 weeks) to grow horseradish from seed indoors before you can transplant them into your garden.

The approximate date of when you should start your horseradish seeds indoors can be found by:

  • Finding the last average frost date HERE
  • And then subtract 56 days from it

You can also find the average last frost date for most major cities in the below chart that I have created:

Ohio Frost Dates

To help ensure the greatest success of your horseradish seeds germinating you should:

  • Use a heat mat to ensure the gardening pot remains at 70 degrees Fahrenheit
  • Use a grow light to control how much light your horseradish seeds receive
  • Water your seeds with a spray bottle to ensure your seeds are not overwatered

It should also be noted that you will not want to introduce your horseradish plants into your garden until 2 weeks after your last frost or else your plant will potentially die or not bear vegetables.
