Swiss chard and arugula can grow together beautifully in the same garden bed.
These two leafy greens are not only compatible companions, but they also support each other’s growth when planted side by side.
If you’ve been wondering whether swiss chard and arugula can grow together successfully, the answer is a resounding yes with the right planning.
You can absolutely plant swiss chard and arugula together because they share similar soil preferences and watering needs.
In this post, we’ll explore the many reasons why growing swiss chard and arugula together works well, the best planting strategies, and a few tips to keep both thriving.
Let’s dig into the wonderful world of companion planting with these two fantastic greens.
Why Swiss Chard And Arugula Can Grow Together
Swiss chard and arugula can grow together because they occupy different spaces in the garden and don’t compete aggressively for nutrients.
Understanding the unique traits of each plant helps you see why this pairing is so successful.
Here are the main reasons these two greens make excellent garden partners.
1. They Have Complementary Growth Habits
Swiss chard grows tall and upright with broad, leafy stalks that reach upward toward the sun.
Arugula, on the other hand, stays low and forms a rosette of lobed leaves close to the ground.
Because they grow at different heights, swiss chard and arugula can grow together without shading each other out.
This vertical layering means you can pack more greens into a small space while both plants get the light they need.
The taller chard acts as a gentle shade provider for arugula during the hottest part of the day.
This natural shade helps arugula stay cool and prevents it from bolting, or going to seed, too quickly.
So when you ask if swiss chard and arugula can grow together, the complementary structure is a huge advantage.
2. They Prefer Similar Soil Conditions
Both swiss chard and arugula thrive in loose, well-draining soil that’s rich in organic matter.
They both prefer a slightly acidic to neutral pH level, somewhere between 6.0 and 7.0.
This means you can prepare one bed for both plants without needing to adjust conditions for each one separately.
Adding compost before planting gives both greens the nutrients they need to establish strong roots.
Since they share these soil preferences, swiss chard and arugula can grow together in the same row or block with ease.
You won’t have to worry about one plant struggling because the soil isn’t right for it.
This shared foundation makes the pair incredibly low-maintenance.
3. Watering Needs Align Perfectly
Swiss chard and arugula both need consistent moisture to produce tender, flavorful leaves.
They like their soil evenly moist but never waterlogged or soggy.
You can water them on the same schedule, typically providing about one inch of water per week.
During hot or dry spells, both plants will appreciate a little extra hydration.
Because their watering needs match so closely, having swiss chard and arugula grow together simplifies your garden routine.
You won’t have to water one plant more than the other, which saves time and prevents mistakes.
This alignment in moisture needs is one of the strongest reasons this pairing works.
4. Natural Pest Deterrence Happens Naturally
Arugula’s peppery, pungent aroma naturally repels certain pests that might otherwise attack swiss chard.
Flea beetles, for example, are often confused by the strong scent of arugula.
When swiss chard and arugula grow together, the arugula acts as a kind of natural shield for the chard.
Meanwhile, swiss chard’s broad leaves provide habitat for beneficial insects that prey on common garden pests.
This mutual protection means you’ll likely see fewer pest problems than if you planted either green alone.
Companion planting like this reduces the need for chemical interventions in your garden.
It’s a win-win situation that keeps both plants healthier and happier.
5. Harvesting Times Extend Your Season
Arugula matures quickly, often ready to harvest in just four to six weeks from seeding.
Swiss chard takes a bit longer, usually around eight to ten weeks before the leaves are large enough to pick.
When you plant them together, you can harvest arugula early while waiting for the chard to mature.
After you’ve cut the arugula, swiss chard will continue producing leaves for months.
This staggered harvest means your garden stays productive longer when swiss chard and arugula grow together.
You get early greens from arugula and a steady supply of chard well into the fall.
The timing works beautifully for a continuous harvest.
Best Practices For Planting Swiss Chard And Arugula Together
Now that you know swiss chard and arugula can grow together, let’s talk about how to set them up for success.
A little planning goes a long way in maximizing the benefits of this pairing.
Follow these practical tips to get the best results from your garden bed.
1. Give Them Enough Space
Even though they grow at different heights, both plants need breathing room to thrive.
Space swiss chard plants about 12 inches apart in rows that are 18 inches apart.
Arugula can be planted closer together, around 6 inches apart, but always leaves room for air circulation.
When you position arugula in front of or between the chard rows, both plants get adequate airflow.
Good spacing prevents fungal diseases and ensures each plant receives enough light.
Remember that swiss chard and arugula can grow together, but they still need their personal space.
Crowding either plant will lead to smaller leaves and increased disease pressure.
2. Interplant In Rows Or Blocks
One effective method is to plant alternating rows of swiss chard and arugula.
Another option is to interplant them within the same row, placing arugula seeds between chard seedlings.
Block planting also works well, where you group a few chard plants surrounded by a border of arugula.
Whichever layout you choose, the key is to maintain the spacing guidelines.
Interplanting maximizes your harvest per square foot of garden space.
It also makes it easier to see both plants thriving side by side.
Try a few different arrangements to see what works best in your specific garden.
3. Timing Your Planting For Cool Weather
Both swiss chard and arugula prefer cool weather and can tolerate light frosts.
You can plant them in early spring as soon as the soil is workable.
For a fall harvest, sow seeds about six to eight weeks before your first expected frost.
Because they can grow together in the same season, you can plant them at the same time.
Succession planting every two to three weeks keeps a continuous supply of both greens coming.
Hot summer temperatures will cause arugula to bolt, so focus on spring and fall plantings.
Swiss chard is more heat-tolerant, but it also prefers milder conditions.
This shared preference for cooler weather reinforces why swiss chard and arugula can grow together.
Potential Challenges When Growing Them Together
While swiss chard and arugula can grow together successfully, a few challenges can arise.
Being aware of these potential issues helps you address them before they become problems.
Here’s what to watch out for.
1. Bolting In Hot Weather
Arugula will quickly bolt, or flower and go to seed, in hot summer temperatures.
Swiss chard is slower to bolt, but it can also be affected by prolonged heat.
To prevent bolting, provide afternoon shade or mulching to keep the soil cool.
Planting swiss chard and arugula together can actually help, as the chard shades arugula.
But for summer harvests, consider planting arugula in a shadier spot.
Also, keep the soil consistently moist to reduce heat stress on both plants.
Regular harvesting of arugula leaves also delays bolting.
2. Competition For Nutrients
While they don’t compete aggressively, both greens are heavy feeders of nitrogen.
To avoid nutrient competition, amend the soil with compost before planting.
You can also feed both plants with a balanced liquid fertilizer every few weeks.
Adding a layer of organic mulch helps retain moisture and slowly releases nutrients.
If you see yellowing leaves, that’s a sign of nitrogen deficiency.
Watch your plants closely and feed them accordingly when swiss chard and arugula grow together.
A little extra feeding ensures both greens stay lush and green.
3. Pests That Target Both Plants
While arugula deters some pests, certain insects like slugs and aphids enjoy both greens.
Check the undersides of leaves regularly for aphid colonies.
Use row covers early in the season to protect young plants from pests.
Handpicking slugs in the evening is an effective, natural control method.
Encourage beneficial insects like ladybugs to visit your garden.
Even though swiss chard and arugula can grow together without major pest issues, vigilance helps.
Catching problems early keeps both plants healthy and productive.
So, Can Swiss Chard And Arugula Grow Together?
Yes, swiss chard and arugula can grow together wonderfully in your garden.
They share similar soil, water, and sunlight needs, making them easy companions.
Their complementary growth habits allow them to coexist without competing for space.
Arugula’s pest-repelling nature protects the chard, while chard offers cooling shade.
You’ll enjoy a longer harvest season by planting these two greens side by side.
With the right spacing and a little attention to timing, the pairing thrives.
So go ahead and plant swiss chard and arugula together for a productive and beautiful garden bed.
Happy gardening, and enjoy your delicious, homegrown salads.
