Do you want to grow kohlrabi in North Carolina, but don’t know when to plant them?
Planting kohlrabi is not as easy as it seems.
- Kohlrabi are not able to survive frost or cold weather under 40 degrees Fahrenheit.
So if you plant them outside too early in the spring they will die. And if you plant them too late, your kohlrabi won’t produce a harvest before the first frost arrives in the fall.
Today, I’m going to teach you the ideal time to plant kohlrabi in North Carolina:

When to Plant Kohlrabi in North Carolina
As you may have already guessed, you need to pay very close attention to your local weather in the spring. 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 kohlrabi outside in North Carolina!
For your reference, I have created this table for average frost dates for most major cities in North Carolina. If your city is not listed below you can find its Last & First Frost Dates HERE.
North Carolina 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 kohlrabi planted outside in North Carolina 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 kohlrabi?
When you know a frost is coming you need to take action.
- If kohlrabi are in pots, bring them inside
- If kohlrabi are in the ground, cover them in burlap and hope they survive
Also, make sure not to plant your kohlrabi in your garden too late.
- Planting kohlrabi too late will cause small kohlrabi or even worse, no kohlrabi.
When Should You Start Your Kohlrabi Seeds Indoors?
Depending on the type of kohlrabi, it takes roughly 35-40 days to grow kohlrabi from seed indoors and then transplant them to your garden.
For a specific date that you should start kohlrabi seeds indoors you should:
- Find the last average frost date HERE
- And then subtract 40 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 kohlrabi 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 kohlrabi plant, increasing its chances of fighting off diseases, insects, droughts, and wet conditions.
