Here is the BEST Time to Start Water Chestnut Seeds in Wisconsin (2023)

Do you want to grow water chestnut seeds in Wisconsin, but don’t know when to start them?

Starting water chestnut seeds is not as easy as it seems.

Here’s why:

  • Water Chestnut 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 Wisconsin’s growing season is not long enough, water chestnut 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 water chestnut seeds indoors in Wisconsin:

When to Start Water Chestnut Seeds Indoors

Depending on the type of water chestnut, it takes roughly 40-60 days (6 to 8 weeks) to grow water chestnut from seed indoors before you can transplant them into your garden.

The approximate date of when you should start your water chestnut 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 water chestnut 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 water chestnut 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 water chestnut plants into your garden until 2 weeks after your last frost or else your plant will potentially die or not bear vegetables.
