Here is the BEST Time to Start Green Bean Seeds in Ohio (2022)

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

Starting green bean seeds is not as easy as it seems.

Here’s why:

  • Green Bean Seeds 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, green bean 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 green bean seeds indoors in Ohio:

When to Start Green Bean Seeds Indoors

Depending on the type of green beans, it takes roughly 14 – 21 days (2 to 3 weeks) to grow green beans from seed indoors before you can transplant them into your garden.

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

  • Finding the last average frost date HERE
  • And then subtract 20 days from it

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

To help ensure the greatest success of your green bean 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 green bean 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 green bean plants into your garden until 2 weeks after your last frost or else your plant will potentially die or not bear vegetables.
