Here is the BEST Time to Start Stevia Seeds in Washington (2023)

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

Starting stevia seeds is not as easy as it seems.

Here’s why:

  • Stevia 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 Washington’s growing season is not long enough, stevia 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 stevia seeds indoors in Washington:

When to Start Stevia Seeds Indoors

Depending on the type of stevia, it takes roughly 56-70 days (8 to 10 weeks) to grow stevia from seed indoors before you can transplant them into your garden.

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

  • Finding the last average frost date HERE
  • And then subtract 70 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 stevia 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 stevia 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 stevia plants into your garden until 2 weeks after your last frost or else your plant will potentially die or not bear vegetables.
