About Growing Kohlrabi? We Go Way Back
I can remember back in “the good ole days” that growing kohlrabi was always destined to be one of the many gardening tasks I had when my dad cultivated veggies in our backyard garden.
He dearly loved those tennis ball sized globes with the stiff branches sticking out of them – like spokes on a bicycle wheel.
My dad would pick a ripe sphere of kohlrabi out of the garden – rinse it off under the garden hose – pull a salt shaker out of his pocket and give it a dose – then happily consume it while watching me weed and mulch our garden.
Personally, I never developed a taste for them until later in life – when I discovered some unique ways to consume them – both raw and cooked.
Kohlrabi – Named By German People
That’s right. Kohlrabi is a German name meaning “cabbage turnip” – kohl (cabbage) – rabi (turnip). This little orb had its beginnings in the 1500’s – in northern Europe – Germany and surrounding areas. Needless to say, German folks around the world have a special place in their heart for this veggie.
It wasn’t until the 19th century that kohlrabi made itself known to gardens and groceries in the U.S.A.
In eastern India – West Bengal and Bangladesh – they identify it as “Ol Kopi” – but, in India’s Kashmir Valley it’s called “Monj-hakh.”
In northern Vietnam, they refer to kohlrabi as “su hào.” In Cyprus, the label is “kouloumpra.”
But, “Kohlrabi by any other name – is still a cabbage turnip!”
What Does Kohlrabi Taste Like?
The short answer? Take a guess…
Since its name actually means “cabbage turnip”, it obviously tastes like a cross between a cabbage and a turnip – only milder and sweeter. And, you can eat every part of it – from the rounded base to the stems, leaves and flowers.
Kohlrabi stems have a texture akin to broccoli stems – while kohlrabi leaves and flowers can be substituted in dishes calling for spinach, collard greens or kale.
I usually skin kohlrabi with a vegetable peeler – just like I do with potatoes. However, kohlrabi skin is completely edible – if you don’t mind its slightly tough and rubbery texture.
Raw Or Cooked Kohlrabi? You Decide!
Latching onto my earlier experiences as a youngster – working in my dad’s garden – I never developed a taste for raw kohlrabi. Although, my wife tells me how much she likes to eat it raw – with a little sea salt – much like my dad enjoyed it. She likes the crunchiness – and, sometimes she dribbles olive oil on her kohlrabi before salting it.
If I have my druthers – I’ll stick to cooking it – sautéed, baked, steamed, boiled in soup, etc. A favorite of mine is a baked dish of kohlrabi – covered with sliced tomatoes and mozzarella cheese. Throw a couple black olives and a few sprigs of rosemary on top and it’s a meal fit for a king!
I’ve even used a mandarin slicer to make my kohlrabi slices paper thin – microwave them on a Pam coated plate for about 3 minutes – add my favorite garlic salt or sour cream powder – and they taste almost like potato chips – except healthier!
Kohlrabi Is Just Another Vegetable That Is Good For You!
Full of vitamins (A, B, C, K), kohlrabi also has a host of other nutrients: calcium, antioxidants, iron, potassium, copper, carotenes, manganese, etc.
So, it makes sense to include these globular, alien-looking veggies in a lifestyle geared to nutritiously achieving a healthy body.
The Best Kohlrabi Varieties
Kohlrabi plants are white, purple, or light green – with White Vienna and Purple Vienna being the most popular. Here are my three favorites – and they all reach full maturity in 7 to 8 weeks at the most.
Planting Kohlrabi Is A Cinch!
The majority of my vegetable seeds go through a standard pre-planting process indoors: germination, transplanting, and hardening off. But, kohlrabi seeds germinate so well in the outdoors that I just stick them directly into the backyard garden.
Don’t forget that wherever they’re planted, they will need at least 6 to 8 hours per day of full sun.
NOTE: Kohlrabi is in the cabbage family. So, as in the case of any veggies in the cabbage family, do NOT plant any member of the family in an area where another member of the family has grown in the last 2 years!
- Till the dirt between 6 and 8 inches deep – and remove clumps, stumps, and stones as much as possible. Rake it smooth.
- Make an inch deep furrow, lay down a half inch layer of Jim’s 50/50 soil mixture, sprinkle seeds along the furrow every inch or so, and cover with a quarter to a half inch of Jim’s soil mixture. Firm the soil and water well.
- Keep the soil visibly moist until the seedlings start to pop up – probably in a couple of weeks – then make sure they get at least an inch of water a week. TIP #1: Using a rain gauge can help a lot to determine if and when to water your plants. TIP #2: Use soaker hoses to get water to your plants. Most plants prefer the soaker hoses – as opposed to overhead watering – by hose or by Mother Nature. Using soaker hoses will reduce the chance of plant diseases.
- Keep rows about 2 feet apart (minimum distance should be a foot and a half).
- When the seedlings are a couple inches tall, thin out the herd – so that the plants are at least 4 to 6 inches apart.
- Keep weeds away – they will steal your plants’ water and nutrients.
- Mulch around the plants – to retain moisture, keep the soil cool, and help prevent weed growth.
Pickin’ Kohlrabi
Once the round little guys get 2 or 3 inches wide, the whole plant can be harvested and eaten. Or, you can wait until they are full size – anywhere from 4 to 6 inches. Just whack them off under the globe with a sharp knife.
After peeling them, place in a sealed plastic bag and refrigerate. They’ll stay fresh for at least a couple of weeks – maybe a little longer.
For longer storage, peel, blanch, and slice them – fill a freezer bag – and pop them in the freezer. They’ll be good for at least a year. And, if you vacuum pack them, they will stay fresh for a couple of years – frozen.
Kohlrabi is also a great candidate for pickling – the same way you would pickle cucumbers. Try it! You’ll like it!
Kohlrabi Enemies
Pests
There are a number of evil critters that attack kohlrabi – but, the most common are cabbage worms, flea beetles, and aphids. They like young plants the most – so, pay attention – and as soon as you spot these varmints, hit them with a good spraying of Ortho Flower, Fruit and Vegetable Insect Killer.
Diseases
Fungal diseases like leaf spot, downy mildew, and powdery mildew are quick to attack kohlrabi – especially if most of the watering is done overhead – instead of with soaker hoses. Attack these diseases quickly with a quality fungicide like Daconil or Physan 20 to put an end to their plant terrorism.
If these diseases overwhelm the plant, it is best to completely remove it, bag it, and put the bag on the curb for the garbage collector. Do not – I repeat – DO NOT – put the diseased plant anywhere close to the garden area or your compost pile. You don’t want any fungal diseases finding their way back into your plants – EVER AGAIN.
Jed And Bessie
My neighbor, Jed, the retired farmer, was looking over my kohlrabi plants recently and he recalled the time his cow, Bessie, had gotten outside the fence and was high tailing it down the road.
He finally caught up with Bessie, threw a rope around her neck, and started leading her back to the barn.
He had walked only a few yards when a truck came barreling down the road and slammed into Bessie – sending Jed and Bessie flying into a ditch. The driver of the truck kept on going – but, Jed saw the name of the trucking company and the truck’s number on the side of the truck just before he passed out.
Jed’s injuries were so severe that he decided to sue the trucking company in court.
During the court proceedings, the trucking company’s fancy lawyer questioned Jed.
“Didn’t you tell the officer at the scene of the accident that you were fine?”
Jed responded.
“Well, let me tell you what happened. I was leading my cow, Bessie, down the road when…”
The lawyer interrupted saying…
“I never asked for details. Answer YES or NO – didn’t you say at the scene of the accident that you were fine?”
Again, Jed said…
“You have to understand. Me and Bessie were walking down the road when…”
For the second time the lawyer interrupted – pleading with the judge…
“Judge, all I’m trying to do is establish that, at the scene of the accident, this man told the police officer that he was just fine! And, now, a month after the accident, he is suing my client. I am convinced that his claim is fraudulent! Would you please tell him to simply answer the question?”
By now, the judge was curious about Jed’s explanation and stated…
“I’d like to hear what Jed has to say about his cow, Bessie. So, you are overruled. Jed, please finish your story.”
Then, Jed happily went on…
“Thank you, your honor.
As I was saying, me and Bessie were walking down the road when this truck came along and smacked into Bessie so hard it knocked both of us head over heels into a deep ditch.
Then the truck driver took off – probably hoping that they wouldn’t get caught.
I was hurtin’ real bad and couldn’t hardly move – and, I know that Bessie was in bad shape, too – ‘cause I could hear her just a moanin’ and a groanin’.
Pretty soon, one of Sheriff Andy’s deputies came by – and, the first thing the deputy heard was the racket Bessie was makin’ – so, he walked over to her – and looked at her real careful like. Then, he took out his gun and shot her right dead between the eyes.
Right after that, Andy’s deputy walked on over to me – with his gun in his hand – and looked down at me saying…
‘Jed, your cow, Bessie, was in such bad shape that I had to shoot her. How are YOU feeling?’
Now, your honor – I was lookin’ over at poor Bessie – and lookin’ at that there gun in the deputy’s hand – and no matter how busted up I was – I just had to say, I FEEL FINE!”
I don’t blame Jed one bit – I think I would have said that I was fine, too – no matter how bad of a shape I was in!
Comments and emails are welcome. Are you a kohlrabi grower? Interested in trying it?

Ok……….now THIS is something I’ve not heard of……….EVER. Being the curious person I am, and somewhat of a green thumber, I’ve got to try this. Even if I don’t like it, it’s interesting. I’m not much of a turnip person or cabbage person, but you mentioned “sweeter” so, I’m in! Keep it coming! Great website and great writing!
Hi John,
I have to say you are in the majority. Not many folks have ever heard of kohlrabi. I tell them that growing it is like growing something from out of this world!
Try the kohlrabi version of potato chips I talked about. You just might find them addictive! I know that I have!

I just love kohlrabi. I love to eat it both raw and cooked, but I find I eat it more often raw than cooked. When I do cook it, I love to roast it in the oven. Honestly, it reminds me of other root veggies. I often will mix root veggies with it, put some olive oil, garlic, salt, and pepper. It’s a fantastic veggie.
Join the club, JB. Even though I wasn’t fond of kohlrabi in my youth, I have come to love it in many ways. My wife is a raw kohlrabi fanatic – but, even though I chew a few raw ones, I still like to cook them in a sauté or a casserole of sorts.
Someday, maybe, kohlrabi will be up there with other famous veggies – if enough folks are exposed to it.
