Yes, you can plant carrots and kohlrabi together, and they actually make excellent garden companions.
Both are cool-season crops that thrive in similar conditions, so pairing them in the same bed is a smart way to maximize your growing space.
If you’ve been wondering whether it’s a good idea to plant carrots and kohlrabi together, the short answer is a resounding yes.
In this post, we’ll dig into why planting carrots and kohlrabi together works so well, how to set it up, and a few tips to make sure both crops flourish side by side.
Let’s get growing.
Why You Can Plant Carrots and Kohlrabi Together
You can plant carrots and kohlrabi together because they share similar growth requirements and don’t compete aggressively for resources.
Here’s why this pairing works:
1. They Love the Same Weather
Carrots and kohlrabi are both cool-weather lovers.
They germinate best when soil temperatures are between 45°F and 75°F, which means spring and fall are prime time for both.
When you plant carrots and kohlrabi together, you’re not forcing one crop to endure conditions it hates.
They’ll grow happily through the same mild temperatures and even tolerate a light frost without fuss.
2. Different Root Depths Mean No Competition
One of the best reasons to plant carrots and kohlrabi together is that they feed at different levels in the soil.
Carrots send their taproots deep, sometimes reaching 8 to 12 inches down.
Kohlrabi, on the other hand, has a shallow, fibrous root system that stays closer to the surface.
This means they aren’t fighting over the same nutrients and moisture space.
Instead, they peacefully share the soil, each taking what it needs from its own zone.
3. Kohlrabi Leaves Don’t Shade Carrots Out
Kohlrabi grows upright with a compact bulb and a small crown of leaves.
It doesn’t spread wide like a zucchini or pumpkin, so it won’t smother your carrot tops.
When you plant carrots and kohlrabi together, the carrots still get plenty of sunlight to fuel their leafy growth.
And the kohlrabi’s modest leaf canopy can even help shade the soil slightly, keeping it cool and moist, which carrots appreciate.
4. They Repel Certain Pests
Companion planting carrots and kohlrabi together has another bonus: pest confusion.
Carrots are often targeted by carrot flies, while kohlrabi can fall victim to cabbage worms and aphids.
When you plant carrots and kohlrabi together, the mixed scents and textures can make it harder for these pests to find their favorite host.
It’s not a foolproof shield, but it certainly helps reduce damage naturally.
How to Plant Carrots and Kohlrabi Together
If you want to plant carrots and kohlrabi together successfully, a little planning goes a long way.
Here’s how to set up your bed:
1. Prepare Loose, Well-Drained Soil
Carrots need loose, sandy loam soil free of rocks and clumps, or they’ll end up forked and stunted.
Kohlrabi isn’t as picky, but it still appreciates good drainage.
Before you plant carrots and kohlrabi together, work the soil at least 10 inches deep and mix in plenty of compost.
This gives carrots room to stretch and kohlrabi a fertile base to feed from.
2. Sow Carrot Seeds Directly
Carrots don’t transplant well, so always sow the seeds straight into the garden.
Scatter or row-plant them about ¼ inch deep, keeping seeds 2 to 3 inches apart.
Since carrot seeds are tiny, you’ll likely need to thin them later, but that’s normal.
When you plant carrots and kohlrabi together, give the carrots their space first, then tuck kohlrabi around them.
3. Set Kohlrabi Starts or Seeds Nearby
Kohlrabi can be started indoors or sown directly, but transplants give you a head start.
Place kohlrabi plants 8 to 10 inches apart in rows or clusters, leaving enough room for their bulbs to swell.
If you plant carrots and kohlrabi together in alternating rows, you’ll make harvesting easier and keep the bed organized.
Just avoid planting kohlrabi so close that its leaves completely cover the carrot rows.
4. Water Consistently and Mulch
Both crops need steady moisture to develop tender roots and crisp bulbs.
Dry spells can make carrots woody and cause kohlrabi to turn tough and pithy.
After you plant carrots and kohlrabi together, add a layer of straw or grass-clipping mulch.
This keeps the soil cool, retains moisture, and suppresses weeds that would otherwise compete with your crops.
Tips for a Successful Carrot and Kohlrabi Pairing
Even though you can plant carrots and kohlrabi together with ease, a few extra tips will boost your results.
1. Keep an Eye on Spacing
The biggest mistake when you plant carrots and kohlrabi together is overcrowding.
Carrots need room to expand, and kohlrabi bulbs need space to round out.
Thin your carrots diligently and don’t let kohlrabi leaves shade them for too long.
2. Fertilize Lightly
Too much nitrogen will make carrots hairy and kohlrabi leafy instead of bulbous.
A balanced organic fertilizer or compost tea once a month is plenty when you plant carrots and kohlrabi together.
3. Harvest at the Right Time
Carrots are ready when their shoulders peek above the soil, usually 60 to 80 days after sowing.
Kohlrabi is best harvested when the bulb is 2 to 3 inches across, before it turns woody.
When you plant carrots and kohlrabi together, you can often harvest kohlrabi first, giving carrots more room to finish.
So, Can You Plant Carrots and Kohlrabi Together?
You can plant carrots and kohlrabi together, and it’s a pairing that makes great use of your garden space.
They share similar weather preferences, root at different depths, and don’t crowd each other out.
With loose soil, consistent watering, and a little spacing discipline, you’ll harvest crisp carrots and tender kohlrabi from the same bed.
So go ahead and plant carrots and kohlrabi together this season.
Your garden will thank you with a double crop of deliciousness.
