Yes, you can plant cauliflower and cabbage together.
Both belong to the same plant family, so they share similar growing needs and won’t fight each other for space or nutrients.
If you’ve been wondering whether cauliflower and cabbage can be planted together, the short answer is a confident yes.
They thrive in the same cool weather, enjoy the same soil conditions, and mature on similar timelines.
In this post, we’ll look at why planting cauliflower and cabbage together works so well, the best ways to do it, and a few things to watch out for along the way.
Let’s dig in.
Why You Can Plant Cauliflower and Cabbage Together
You can plant cauliflower and cabbage together because they’re basically cousins in the garden.
Here’s why this pairing works so well:
1. They Belong to the Same Plant Family
Cauliflower and cabbage are both members of the brassica family, also known as cole crops.
This family includes broccoli, kale, Brussels sprouts, and turnips too.
Because they’re relatives, planting cauliflower and cabbage together means they respond to the same temperatures, watering schedules, and soil types.
You won’t have to juggle completely different care routines for each one.
When you plant cauliflower and cabbage side by side, they’re basically speaking the same gardening language.
2. They Love the Same Cool Weather
Both cauliflower and cabbage are cool-season crops.
They grow best when daytime temperatures sit between 60°F and 70°F.
This is why planting cauliflower and cabbage together in spring or fall works beautifully.
They both tolerate a light frost, which makes them perfect companions for an early or late garden.
If you plant cauliflower and cabbage at the same time, they’ll hit their peak growing window together.
3. They Need Similar Soil and Water
Cauliflower and cabbage both prefer rich, well-draining soil with a pH between 6.0 and 6.8.
They’re heavy feeders, meaning they need plenty of nitrogen to grow those big leafy heads.
When you plant cauliflower and cabbage together, you can amend the soil once and feed both crops at the same time.
Both also need consistent moisture, about an inch of water per week.
So planting cauliflower and cabbage together actually simplifies your watering routine.
4. They Mature on Similar Timelines
Most cabbage varieties mature in 70 to 100 days.
Cauliflower typically takes 55 to 100 days, depending on the variety.
This means when you plant cauliflower and cabbage together, you can often harvest them around the same time.
That’s convenient for planning your garden beds and your kitchen menus.
How to Plant Cauliflower and Cabbage Together
Planting cauliflower and cabbage together is easy once you know the basics.
Here’s how to set them up for success:
1. Give Them Enough Space
Both crops need room to spread out.
Space cauliflower and cabbage about 18 to 24 inches apart in rows that are 24 to 36 inches apart.
If you plant cauliflower and cabbage too close, they’ll compete for nutrients and airflow.
Good spacing also helps prevent disease from spreading between plants.
2. Prepare the Soil Well
Before you plant cauliflower and cabbage, work in plenty of compost or aged manure.
These crops are hungry, so a nutrient-rich start makes a big difference.
You can also add a balanced fertilizer at planting time.
When you plant cauliflower and cabbage in soil that’s already rich, you’ll see stronger growth from day one.
3. Water Consistently
Consistent moisture is key when you plant cauliflower and cabbage together.
Dry spells can cause cabbage to split and cauliflower to button, meaning tiny heads.
Aim for about an inch of water per week, either from rain or irrigation.
Mulching around your plants helps lock in moisture and keeps the soil cool.
4. Watch for Shared Pests
Since cauliflower and cabbage are in the same family, they attract the same pests.
Cabbage worms, aphids, and flea beetles will happily munch on both.
When you plant cauliflower and cabbage together, scout for pests regularly.
Row covers can protect both crops without chemicals.
Just check under leaves often, because pests love to hide there.
Things to Keep in Mind When You Plant Cauliflower and Cabbage Together
Planting cauliflower and cabbage together comes with a few caveats.
First, avoid planting them where brassicas grew last year.
Crop rotation helps prevent soil-borne diseases that affect both plants.
Second, give them breathing room so air circulates freely.
Third, keep an eye on cauliflower especially, since it’s a bit fussier than cabbage.
If cauliflower struggles, it won’t necessarily drag cabbage down with it, but both benefit from attentive care.
So, Can You Plant Cauliflower and Cabbage Together?
Yes, you can plant cauliflower and cabbage together.
They share the same family, weather preferences, soil needs, and growth timelines.
When you plant cauliflower and cabbage together, you save space, simplify care, and set yourself up for a bountiful harvest.
Just give them room to grow, feed them well, and watch for the pests they have in common.
With a little planning, planting cauliflower and cabbage together can be one of the smartest moves in your cool-season garden.
