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

Whether growing indoors or in a garden, starting brussel sprout seeds is not as easy as it seems.

Here’s why:

• Brussel Sprout 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 Wisconsin’s growing season is not long enough, brussel sprout 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 brussel sprout seeds indoors in Wisconsin:

When to Start Brussel Sprout Seeds Indoors

• And then subtract 60 days from it

To help ensure the greatest success of your brussel sprout 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 brussel sprout 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.
