Do you want to grow dutch iris seeds in Wisconsin, but don’t know when to start them?
Starting dutch iris seeds is not as easy as it seems.
- Dutch Iris 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, dutch iris 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 dutch iris seeds indoors in Wisconsin:

When to Start Dutch Iris Seeds Indoors
Depending on the type of dutch iris, it takes roughly 60-90 days (2 to 3 months) to grow dutch iris from seed indoors before you can transplant them into your garden. And it could take 1 year for your dutch iris to bloom!
The approximate date of when you should start your dutch iris seeds indoors can be found by:

To help ensure the greatest success of your dutch iris 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 dutch iris 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 dutch iris plants into your garden until 2 weeks after your firstfrost or else your plant will potentially die or not bloom
