Yes, you can plant broccoli and Brussels sprouts together, and they actually make excellent garden companions.
Both belong to the same plant family, which means they share similar growing requirements for sunlight, soil, and water.
If you’ve been wondering whether you can plant broccoli and Brussels sprouts together without causing problems in your garden, the short answer is absolutely yes.
These two cool-season crops thrive in nearly identical conditions and can be grown side by side in the same bed.
In this post, we’ll explore why broccoli and Brussels sprouts grow well together, how to plant them for the best results, and a few tips to keep both crops happy and productive.
Let’s dig in.
Why You Can Plant Broccoli and Brussels Sprouts Together
You can plant broccoli and Brussels sprouts together because they belong to the same family and share nearly identical growing needs.
Here’s why this pairing works so well:
1. They’re Both Members of the Brassica Family
Broccoli and Brussels sprouts are both brassicas, also known as cole crops.
This means they evolved in similar climates and have matching preferences for temperature, moisture, and soil composition.
If you can plant broccoli and Brussels sprouts together, you can treat them almost like twins in the garden since they need the same care.
2. They Share the Same Soil Requirements
Both crops prefer well-draining, loamy soil with a pH between 6.0 and 7.0.
They also both benefit from soil rich in organic matter and plenty of compost worked in before planting.
Since their soil needs align so closely, you can plant broccoli and Brussels sprouts together in one prepared bed without having to customize the soil for each one.
3. They Need the Same Amount of Sunlight
Broccoli and Brussels sprouts both want full sun, ideally six to eight hours of direct light per day.
This makes planning your garden bed a breeze.
You can plant broccoli and Brussels sprouts together in an area that gets plenty of morning sun with some afternoon shade in warmer climates.
4. They’re Both Cool-Season Crops
Both vegetables love cool weather and actually improve in flavor after a light frost.
They’re typically planted in early spring or late summer for a fall harvest.
Because their planting windows overlap almost perfectly, you can plant broccoli and Brussels sprouts together and harvest them around the same time.
5. They Have Similar Watering Needs
Neither crop likes to dry out, and both need about an inch to an inch and a half of water per week.
Consistent moisture is key for both, especially when the heads and sprouts are forming.
When you plant broccoli and Brussels sprouts together, a single watering schedule keeps both crops happy.
How to Plant Broccoli and Brussels Sprouts Together
To plant broccoli and Brussels sprouts together successfully, you just need to plan your spacing and timing carefully.
Here’s how to do it:
1. Give Each Plant Enough Room
Broccoli needs about 18 to 24 inches of space between plants, while Brussels sprouts need roughly the same.
If you plant broccoli and Brussels sprouts together, space them so each plant has room for its roots to spread.
A good rule of thumb is to alternate them in rows, leaving 20 to 24 inches between every plant.
2. Start Seeds or Transplants at the Same Time
Since both crops have similar maturity rates, you can plant broccoli and Brussels sprouts together from seeds or transplants in the same week.
Start them indoors about six weeks before your last frost date or direct sow them outdoors when the soil is workable.
3. Feed Them Both Consistently
Both crops are heavy feeders and love nitrogen-rich soil.
When you plant broccoli and Brussels sprouts together, side-dress them with compost or a balanced fertilizer a few weeks after planting.
This keeps both crops growing strong through the season.
4. Watch for Shared Pests
Because broccoli and Brussels sprouts share a family, they also share common pests like cabbage worms and aphids.
When you plant broccoli and Brussels sprouts together, check both crops regularly for signs of damage.
Row covers can help protect them without needing chemical sprays.
Tips for Growing Broccoli and Brussels Sprouts Together
Here are a few extra pointers when you plant broccoli and Brussels sprouts together:
1. Don’t Plant Them in the Same Spot Year After Year
Rotate brassicas to a new spot each season to avoid soil-borne diseases.
2. Mulch to Retain Moisture
A layer of straw or compost keeps the soil cool and moist, which both crops love.
3. Harvest at the Right Time
Cut broccoli heads while buds are tight, and pick Brussels sprouts from the bottom of the stalk upward as they firm up.
So, Can You Plant Broccoli and Brussels Sprouts Together?
You can plant broccoli and Brussels sprouts together, and it’s actually one of the easiest companion pairings in the garden.
Both crops share the same soil, sunlight, water, and temperature needs, which makes your job simple.
Just give them enough space, keep the soil moist, and watch for shared pests.
Hope this post has helped you see why you can plant broccoli and Brussels sprouts together and how to do it successfully.
