Swiss chard and arugula can grow together beautifully in the same garden bed.
These two leafy greens are fantastic companions because they share similar growing requirements but don’t compete aggressively for space or nutrients.
If you’ve been wondering whether can swiss chard and arugula grow together without one choking out the other, the answer is a confident yes.
In fact, pairing these two greens can maximize your harvest, improve soil use, and give you a continuous supply of fresh salad leaves all season long.
In this post, we’ll dig into why swiss chard and arugula can grow together, how to plant them side by side, and the simple tricks to keep both thriving.
Let’s get started.
Why Swiss Chard And Arugula Can Grow Together
Swiss chard and arugula can grow together because they occupy different layers of the garden and have complementary growth habits.
Swiss chard is a tall, upright plant with broad leaves and thick stalks, while arugula stays low and spreads out close to the ground.
This means they won’t shade each other out or fight for the same horizontal space.
Let’s break down the main reasons this pairing works so well.
1. Similar Soil and Sun Preferences
Both swiss chard and arugula can grow together in the same type of soil, which makes planning your bed super easy.
They both love well-draining, loamy soil that’s rich in organic matter with a pH between 6.0 and 7.0.
When it comes to sunlight, both greens prefer full sun but will tolerate partial shade, especially in hotter climates.
So if you have a spot that gets about six hours of sun, you can confidently plant swiss chard and arugula together there.
2. Different Root Depths Reduce Competition
A big reason why swiss chard and arugula can grow together is that their roots don’t clash underground.
Swiss chard develops a deeper taproot that reaches down for moisture and nutrients.
Arugula, on the other hand, has a shallow, fibrous root system that stays near the soil surface.
This means they can grow together without stealing water or food from each other, making them ideal neighbors.
3. Fast Growth vs. Slow Growth Balance
Arugula is a quick-growing crop that’s ready to harvest in as little as three to four weeks.
Swiss chard takes a bit longer, usually maturing in seven to eight weeks.
Because arugula comes and goes quickly, you can plant swiss chard and arugula together and harvest the arugula first.
Once the arugula is done, the swiss chard gets more room and light to keep growing strong.
This staggered timeline is one of the best practical reasons the two can grow together.
How To Plant Swiss Chard And Arugula Together
Now that you know can swiss chard and arugula grow together, let’s talk about the best way to set up your bed.
A little planning goes a long way to make sure both greens thrive side by side.
1. Give Each Plant Enough Spacing
Even though they can grow together, swiss chard and arugula still need their personal space.
Space swiss chard plants about 8 to 12 inches apart to allow their leaves to spread out fully.
Arugula can be planted closer together, around 4 to 6 inches apart, since you’ll be harvesting it young.
You can plant arugula in between rows of swiss chard or scatter it along the edges of the bed.
This way, they can grow together without crowding each other out.
2. Stagger Your Planting Times
To get the most out of your space, you can sow arugula seeds a couple of weeks before swiss chard.
Since arugula grows fast, it will be ready to harvest just as the swiss chard starts to size up.
Alternatively, you can plant swiss chard and arugula together at the same time if you plan to pick arugula as baby greens.
Either way, the key is to harvest arugula frequently so it doesn’t take over the bed.
3. Keep the Soil Moist but Not Waterlogged
Both greens appreciate consistent moisture, so watering is essential when they grow together.
Aim to keep the top inch of soil lightly moist, especially during dry spells.
Using a layer of mulch around your plants helps retain moisture and keeps the soil cool.
Just be careful not to overwater, as soggy conditions can lead to root rot for both crops.
Benefits Of Growing Swiss Chard And Arugula Together
There are plenty of perks beyond just saving space when you decide to grow these two together.
1. Natural Pest Deterrence
Arugula has a peppery, pungent aroma that can help mask the scent of swiss chard from common pests.
Leaf miners and aphids are sometimes less attracted to swiss chard when it’s planted alongside strong-smelling herbs or greens like arugula.
So growing swiss chard and arugula together can act as a simple form of natural pest control.
2. Continuous Harvest From One Bed
When can swiss chard and arugula grow together, you essentially get two crops from the same patch of soil.
Arugula gives you quick salads while you wait for swiss chard to mature.
Then, once arugula bolts in the heat, swiss chard takes over as your main leafy green.
This extends your harvest window and means you always have something fresh to pick.
3. Better Soil Health and Coverage
The dense, low growth of arugula acts as a living mulch around the base of swiss chard plants.
This ground cover helps suppress weeds and keeps the soil from drying out too quickly.
It also reduces soil erosion and keeps the root zone cooler in summer.
So swiss chard and arugula can grow together in a way that benefits the soil as much as your dinner plate.
Common Mistakes To Avoid With This Pairing
Even though can swiss chard and arugula grow together easily, there are a few pitfalls to watch out for.
1. Letting Arugula Bolt
As temperatures rise, arugula will quickly bolt and turn bitter.
If you let arugula go to flower, it can get tall and leggy, shading out the swiss chard.
To prevent this, harvest arugula regularly and try to plant it in early spring or fall when it’s cooler.
2. Overcrowding the Bed
It’s tempting to sow lots of seeds, but overcrowding will stress both plants.
If arugula grows too thick, it can block airflow and trap moisture around swiss chard stems.
Thin your seedlings and keep harvesting arugula so both crops can grow together comfortably.
3. Ignoring Nutrient Needs
Swiss chard is a heavy feeder and really appreciates a nitrogen-rich fertilizer.
Arugula is less demanding, but it still benefits from feeding.
Before planting, mix in plenty of compost. Then side-dress with a balanced organic fertilizer halfway through the season.
This ensures both greens have the energy they need to grow together successfully.
So, Can Swiss Chard And Arugula Grow Together?
Swiss chard and arugula can grow together, and they actually make one of the best companion pairings in the vegetable garden.
They share similar soil, sun, and water needs while avoiding direct competition because of their different sizes, root depths, and growth rates.
Plus, arugula’s quick harvest and pest-deterring scent make it a valuable ally for the slower-growing swiss chard.
Just remember to give them adequate spacing, keep the soil consistently moist, and harvest arugula before it bolts.
With these simple practices, you can plant swiss chard and arugula together and enjoy a continuous bounty of homegrown greens.
So go ahead, grab some seeds, and get ready to see how well swiss chard and arugula can grow together in your own backyard.
