Yes, you can plant Brussels sprouts with squash, and it can actually work quite well in the garden.
When you plant Brussels sprouts with squash, you’re combining two plants that have different growth habits but can share space if you manage them right.
If you’ve been wondering whether you can plant Brussels sprouts with squash, the short answer is yes, as long as you give them enough room and meet their basic needs.
In this post, we’ll look at why planting Brussels sprouts with squash is possible, the benefits of pairing them, and how to do it the right way.
Let’s get growing.
Why You Can Plant Brussels Sprouts With Squash
You can plant Brussels sprouts with squash because these two crops have compatible growing requirements and don’t compete too aggressively for the same resources.
Here’s why this pairing works:
1. They Use Different Garden Space
Brussels sprouts grow tall and upright, forming a single stalk with sprouts along the stem.
Squash, on the other hand, spreads out horizontally along the ground with long vines.
This means when you plant Brussels sprouts with squash, the Brussels sprouts take up the vertical space while the squash covers the ground.
They’re not fighting for the same real estate, which makes them natural companions in a small garden.
2. Both Like Full Sun
Brussels sprouts and squash both thrive in full sun, needing at least six to eight hours of direct sunlight each day.
Since they share the same light preference, you don’t have to worry about one shading out the other when you plant Brussels sprouts with squash.
Just make sure the squash vines don’t completely smother the Brussels sprout stalks as they grow.
3. Similar Soil and Water Needs
Both crops prefer well-drained, fertile soil rich in organic matter.
They also need consistent moisture to grow well, so you can water them on the same schedule.
That said, squash tends to be thirstier than Brussels sprouts, so you’ll want to keep an eye on the squash and give it extra water when needed.
When you plant Brussels sprouts with squash, you may actually find that they help each other, because the squash leaves shade the soil and help retain moisture for the Brussels sprouts.
4. They Don’t Share Major Pests
One of the best reasons to plant Brussels sprouts with squash is that they don’t attract the same pests.
Brussels sprouts deal with cabbage worms, aphids, and flea beetles.
Squash is more likely to attract squash bugs, vine borers, and cucumber beetles.
By planting Brussels sprouts with squash, you reduce the risk of a single pest wiping out both crops.
Benefits of Planting Brussels Sprouts With Squash
There are real advantages to growing these two together, and they go beyond just saving space.
1. Better Use of Garden Space
If you have a small garden, you can plant Brussels sprouts with squash to maximize every square foot.
The squash fills in the gaps between the tall Brussels sprout stalks, and nothing goes to waste.
2. Natural Weed Suppression
Squash vines and their large leaves create a living mulch that shades the soil and suppresses weeds.
When you plant Brussels sprouts with squash, you’ll spend less time pulling weeds around your Brussels sprouts.
3. Improved Moisture Retention
The broad squash leaves help keep the soil cool and moist, which benefits the shallow roots of Brussels sprouts.
This means you can plant Brussels sprouts with squash and cut back on how often you water.
4. Pollinator Attraction
Squash flowers are a magnet for bees and other pollinators.
Those same pollinators will visit your garden and help keep the overall ecosystem healthy, which is good news for everything you’re growing.
How to Plant Brussels Sprouts With Squash
To make this pairing work, timing and spacing matter.
1. Give Them Enough Space
Plant your Brussels sprouts about 18 to 24 inches apart in rows.
Then plant squash on the edges or between the rows, giving each squash plant at least 3 to 4 feet of room to spread.
If you plant Brussels sprouts with squash too close together, the squash vines can overtake the Brussels sprouts.
2. Plant at the Right Time
Brussels sprouts are a cool-season crop, so start them in early spring or late summer.
Squash is a warm-season crop, so plant it after the last frost.
You can still plant Brussels sprouts with squash by starting your Brussels sprouts first and then adding squash once the soil warms up.
3. Support the Brussels Sprouts
Brussels sprouts can get top-heavy and may need staking.
If you plant Brussels sprouts with squash, the squash vines won’t offer much support, so stake or cage your Brussels sprouts to keep them upright.
4. Keep Up With Watering
Both crops need steady moisture, so water deeply once or twice a week.
When you plant Brussels sprouts with squash, aim to keep the soil consistently moist but never soggy.
5. Feed the Soil, Not Just the Plants
Mix compost or aged manure into the soil before planting.
If you plant Brussels sprouts with squash in rich soil, you’ll need fewer supplemental fertilizers.
What to Watch Out For
Even though you can plant Brussels sprouts with squash, there are a couple of things to keep in mind.
Squash vines can grow aggressively and shade out smaller plants.
Keep an eye on them and gently redirect vines away from your Brussels sprouts if they start to smother the stalks.
Also, both crops are heavy feeders, so avoid planting them in the same spot year after year to prevent soil depletion.
So, Can You Plant Brussels Sprouts With Squash?
Yes, you can plant Brussels sprouts with squash, and it can be a smart way to use your garden space.
You can plant Brussels sprouts with squash as long as you give them room, water them well, and keep an eye on those sprawling squash vines.
So if you’ve been asking whether you can plant Brussels sprouts with squash, go ahead and try it.
With a little planning, you can plant Brussels sprouts with squash and enjoy a healthy harvest of both.
