Here is the BEST Time to Start Valerian Seeds in Oklahoma (2023 Guide)

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

Starting valerian seeds is not as easy as it seems.

Here’s why:

  • Valerian Seeds must be consistently 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 Oklahoma’s growing season is not long enough, valerian 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 valerian seeds indoors in Oklahoma:

When to Start Valerian Seeds Indoors

Depending on the type of valerian, it takes roughly 14-21 days (2 to 3 weeks) to grow valerian from seed indoors before you can transplant them into your garden. And it could take 2 years for your valerian to bloom!

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

  • Finding the last average frost date HERE
  • And then subtract 14 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 valerian 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 valerian 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 valerian plants into your garden until 2 weeks after your last frost or else your plant will potentially die or not bloom
