Do you want to grow fall flowers in Michigan, but don’t know when to plant them?
Planting fall flowers is not as easy as it seems.
- Fall Flowers are not able to survive weather above 80 degrees Fahrenheit.

Today, I’m going to teach you the ideal time to plant fall flowers in Michigan:

When to Plant Fall Flowers in Michigan
As you may have already guessed, you need to pay very close attention to your local weather in the fall. Specifically, you are going to need to watch when the last frost occurs.
In general, when there hasn’t been heat over 80 degrees for two weeks, you are SAFE to plant your fall flowers outside in Michigan!
For your reference, I have created this table for average frost dates for most major cities in Michigan. If your city is not listed below you can find its Last & First Frost Dates HERE.
Michigan Last & First Frost Dates
Unfortunately, Mother Nature plays cruel tricks on us every year.
It should be noted that the above dates are just averages.
There are years when the last 80 degree Fahrenheit weather is later. Sometimes, the warm day happens much earlier and you can get your fall flowers planted outside in Michigan much quicker.
Like I said before, you need to be very diligent in checking your local weather.
When Should You Start Your Fall Flower Seeds Indoors?
Depending on the type of fall flower, it takes roughly 40-80 days to grow fall flowers from seed indoors and then transplant them to your garden.
For a specific date that you should start fall flower seeds indoors you should:
- Find the first average frost date HERE
- And then subtract 40 – 80 days from it
Not only this, but I recommend again paying close attention to your local weather report.
It should also be noted that the best technique for bringing your fall flower plants outside is to introduce them (in their pots) outside for an hour. And then increase the amount of time they spend outside each day by an hour until they have been outside for 8 hours.
This will “hardened” your fall flower plant, increasing its chances of fighting off diseases, insects, droughts, and wet conditions.
