Yes, you can plant broccoli and Brussels sprouts together, and they actually make excellent garden companions.
Both are cool-season brassicas that share similar growing requirements, so planting broccoli and Brussels sprouts together is a smart way to maximize your garden space.
They thrive in the same soil conditions, need the same amount of water, and even mature around the same time of year.
This makes them a natural pairing for any vegetable garden.
In this post, we’ll explore why you can plant broccoli and Brussels sprouts together, how to set them up for success, and what to watch out for along the way.
Let’s dig in.
Why You Can Plant Broccoli and Brussels Sprouts Together
You can plant broccoli and Brussels sprouts together because they’re basically garden siblings.
Here’s why this pairing works so well:
1. They’re Both Cool-Season Crops
Broccoli and Brussels sprouts both love cool weather and actually taste sweeter after a light frost.
They grow best when temperatures stay between 60°F and 70°F, which means they follow the same planting calendar.
If you plant broccoli and Brussels sprouts together, you won’t have to fuss over different planting schedules or worry about one crop bolting while the other is still settling in.
2. They Share the Same Soil and Water Needs
Both crops prefer well-draining soil rich in organic matter with a pH between 6.0 and 7.0.
They also need consistent moisture, about an inch of water per week, to develop properly.
When you plant broccoli and Brussels sprouts together, you can water and amend the soil once for both crops instead of treating them like picky, high-maintenance guests with separate menus.
3. They Have Matching Sun Requirements
Broccoli and Brussels sprouts both need full sun, ideally six to eight hours a day.
That means you can place them side by side in the sunniest part of your garden without one shading out the other.
4. They Attract the Same Pests (Which Helps You Plan)
Here’s the honest part: both crops attract cabbage worms, aphids, and flea beetles.
But that’s actually a plus when you plant broccoli and Brussels sprouts together because you can use the same pest control strategy for both, like row covers or companion planting with aromatic herbs.
One plan, two crops protected.
How to Plant Broccoli and Brussels Sprouts Together
Planting broccoli and Brussels sprouts together is straightforward if you follow a few smart spacing rules.
Here’s how to do it:
1. Give Them Enough Room
Broccoli needs about 18 to 24 inches of space between plants, while Brussels sprouts need roughly 18 inches.
Don’t cram them together just because they’re friends.
Proper spacing keeps airflow moving, which reduces the risk of disease when you plant broccoli and Brussels sprouts together.
2. Start Seeds Indoors or Buy Transplants
Both crops do well when started indoors six to eight weeks before your last frost date.
You can also buy transplants and set them out at the same time.
Since both are cool-season crops, planting broccoli and Brussels sprouts together in early spring or late summer works beautifully.
3. Feed the Soil Before Planting
Work in compost or aged manure before planting.
Brassicas are heavy feeders, so when you plant broccoli and Brussels sprouts together, they’ll both benefit from that rich, fertile start.
4. Mulch and Water Consistently
Add a layer of mulch to retain moisture and keep the soil cool.
Then water deeply once a week rather than a light sprinkle every day.
Consistent watering is especially important when you plant broccoli and Brussels sprouts together because stress can cause broccoli to bolt and Brussels sprouts to form loose, airy heads.
Tips for Growing Broccoli and Brussels Sprouts Together
Want the best results when you plant broccoli and Brussels sprouts together?
Keep these tips in mind:
1. Harvest at Different Times
Broccoli usually matures faster than Brussels sprouts.
That means you can harvest your broccoli while the Brussels sprouts are still developing their little sprouts along the stalk.
This staggered harvest is why you can plant broccoli and Brussels sprouts together without them competing for the same harvest window.
2. Watch for Pests Regularly
Check the undersides of leaves for cabbage worm eggs and aphids.
Since both crops share the same pests, a weekly inspection helps you catch problems before they spread when you plant broccoli and Brussels sprouts together.
3. Avoid Planting Them Where Brassicas Grew Last Year
Crop rotation matters.
If you plant broccoli and Brussels sprouts together, make sure that spot hasn’t hosted cabbage, kale, or cauliflower in the past two to three years to avoid soil-borne diseases.
So, Can You Plant Broccoli and Brussels Sprouts Together?
Yes, you can plant broccoli and Brussels sprouts together, and they make a fantastic team in the garden.
They share the same cool-season preferences, soil needs, and sun requirements, so you can plant broccoli and Brussels sprouts together without doubling your workload.
Just give them proper spacing, consistent water, and a watchful eye for pests, and you’ll be rewarded with two harvests from one well-planned garden bed.
Happy planting.
