You can plant kale with broccoli, and it’s actually a pairing that works beautifully in the garden.
Both are cool-season crops that love similar growing conditions, so they make fantastic garden companions.
If you’ve been wondering whether you can plant kale with broccoli, the short answer is yes, and there are some real benefits to doing it.
In this post, we’ll explore why kale and broccoli grow well together, how to plant them properly, and a few things to keep in mind for the best harvest.
Let’s dig in.
Why You Can Plant Kale With Broccoli
You can plant kale with broccoli because these two brassicas share nearly identical needs, which makes them easy to grow side by side.
1. They Thrive in the Same Conditions
Kale and broccoli both enjoy cool weather and perform best when temperatures stay between 60°F and 70°F.
They need full sun but tolerate light shade, and they love rich, well-drained soil with a pH between 6.0 and 7.0.
Because their requirements line up so well, planting kale with broccoli means you can tend to both crops with the same watering and feeding routine.
2. Similar Spacing and Growth Habits
Broccoli grows upright and forms a central head, while kale spreads out with leafy foliage.
That height difference is a plus, because kale fills in the lower gaps while broccoli reaches upward.
When you plant kale with broccoli, give each plant about 18 to 24 inches of space so their roots and leaves have room to breathe.
3. Shared Harvest Windows
Both crops mature in roughly the same timeframe, so you can plant kale with broccoli at the same time and harvest them together.
That makes planning your garden simpler and means you’ll have plenty of greens for salads and stir-fries at once.
4. A Few Pests Get Confused
Here’s a small bonus: when you plant kale with broccoli, the mixed scents can make it harder for certain pests to zero in on a single crop.
It’s not a guarantee, but diversity in the bed can help reduce cabbage worms and aphid pressure somewhat.
How to Plant Kale With Broccoli
If you want to plant kale with broccoli successfully, a little planning before you put seeds or seedlings in the ground goes a long way.
1. Start With Healthy, Rich Soil
Both crops are heavy feeders, so work plenty of compost into the bed before planting.
Aim for loose, well-drained soil that holds moisture without staying soggy.
2. Give Each Plant Enough Room
When you plant kale with broccoli, don’t crowd them.
Space broccoli about 18 to 24 inches apart and kale roughly 12 to 18 inches apart, depending on the variety.
Good airflow between plants is one of the best ways to keep disease at bay.
3. Water Consistently
These crops both need about an inch or two of water per week.
Water at the base of the plants rather than overhead to keep leaves dry and discourage fungal problems.
4. Mulch to Keep Things Even
A layer of mulch helps retain moisture and keeps the soil temperature stable.
Since you can plant kale with broccoli in the same bed, one layer of mulch covers both crops at once.
5. Feed Lightly but Regularly
A side dressing of compost or a balanced fertilizer a few weeks after planting keeps both crops growing strong.
Avoid too much nitrogen, or you’ll get lots of leaves and weak broccoli heads.
Things to Watch Out for When You Plant Kale With Broccoli
Even though it’s easy to plant kale with broccoli, a couple of cautions are worth knowing.
1. Don’t Replant the Same Spot Year After Year
Both are brassicas, which means they share the same soil-borne diseases and pests.
Rotate your crops so kale and broccoli don’t follow each other in the same bed season after season.
2. Watch for Shared Pests
Cabbage worms, aphids, and flea beetles enjoy both crops equally.
Check leaves regularly and handpick pests or use row covers to protect your plants early on.
3. Keep an Eye on Nutrients
Since both crops feed heavily, the soil can run low on nutrients by mid-season.
A mid-season compost top-up helps keep both kale and broccoli thriving.
So, Can You Plant Kale With Broccoli?
You can plant kale with broccoli, and doing so is a smart move for most gardeners.
These two cool-season crops share the same sun, soil, water, and spacing needs, so they grow happily side by side.
Just give them room, keep the soil rich and moist, rotate your beds each season, and stay on top of shared pests.
Hope this post has helped you see why you can plant kale with broccoli and how to get the most from both crops in the same bed.
