Do you want to grow candytuft in Iowa, but don’t know when to plant them?
Planting candytuft is not as easy as it seems.
- Candytuft are not able to survive frost or cold weather under 50 degrees Fahrenheit.
So if you plant them outside too early in the fall they will die. And if you plant them too late, your candytuft won’t produce a bloom.
Today, I’m going to teach you the ideal time to plant candytuft in Iowa:

When to Plant Candytuft in Iowa
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 a frost for two weeks, you are SAFE to plant your candytuft outside in Iowa!
For your reference, I have created this table for average frost dates for most major cities in Iowa. If your city is not listed below you can find its Last & First Frost Dates HERE.
Iowa 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 frost comes MUCH later. Sometimes, the last frost happens much earlier and you can get your candytuft planted outside in Iowa much quicker.
Like I said before, you need to be very diligent in checking your local weather.
So what happens if a frost comes AFTER you plant your candytuft?
When you know a frost is coming you need to take action.
- If candytuft are in pots, bring them inside
- If candytuft are in the ground, cover them in burlap and hope they survive
Also, make sure not to plant your candytuft in your garden too late.
- Planting candytuft too late will cause small blooms or even worse, no blooms.
When Should You Start Your Candytuft Seeds Indoors?
Depending on the type of candytuft, it takes roughly 16 to 20 days to grow candytuft from seed indoors and then transplant them to your garden. And then another 2 months to bloom!
For a specific date that you should start candytuft seeds indoors you should:
- Find the last average frost date HERE
- And then subtract 16 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 candytuft 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 “harden” your candytuft plant, increasing its chances of fighting off diseases, insects, droughts, and wet conditions.
