Do you want to grow onion seeds in Arkansas, but don’t know when to start them?
Whether growing indoors or in a garden, starting onion seeds is not as easy as it seems.
Here’s why:
- Onion 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 Arkansas’s growing season is not long enough, onion 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 onion seeds indoors in Arkansas:

When to Start Onion Seeds Indoors
Depending on the type of onions, it takes roughly 40-60 days (6 to 8 weeks) to grow onions from seed indoors before you can transplant them into your garden.
The approximate date of when you should start your onion seeds indoors can be found by:
- Finding the last average frost date HERE
- And then subtract 60 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 onion 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 onion seeds receive
- Water your seeds with a spray bottle to ensure your seeds are not overwatered
Once your seedlings are ready, you can read how to transplant your plant HERE.
