The best plants to put next to Swiss chard are those that share similar growing conditions and offer some form of mutual benefit.
In this post, we’ll explore the best companion plants for Swiss chard, what to avoid planting nearby, and how these pairings help your garden.
Let’s dig into the wonderful world of companion planting with this leafy green.
Why Choosing What To Plant Next To Swiss Chard Matters
When you decide what to plant next to Swiss chard, you’re not just filling garden space, you’re creating a miniature ecosystem.
Companion planting is an age-old practice where certain plants support each other when grown in close proximity.
The right neighbors can repel destructive insects, attract beneficial predators, and even improve soil nutrients for your Swiss chard.
Getting this right means healthier plants, bigger harvests, and less need for chemical interventions.
It’s all about working with nature instead of against it.
1. Pest-Deterring Herbs as Ideal Neighbors
One of the smartest moves is planting aromatic herbs next to Swiss chard because their strong scents confuse and repel common pests.
Swiss chard is often targeted by leaf miners, aphids, and flea beetles, but herbs can change that.
Planting herbs next to Swiss chard like mint, sage, and rosemary creates a fragrant barrier that pests find overwhelming.
For example, sage is particularly effective at deterring flea beetles that love to chew holes in chard leaves.
Mint, while needing to be contained, is fantastic at repelling ants and aphids which can spread disease to your chard.
Just remember to plant mint in a pot sunk into the ground to stop it from taking over the bed.
I also recommend dill and cilantro because they attract beneficial wasps that prey on aphids and other soft-bodied pests.
These herbs are low-growing and won’t compete for sunlight, making them perfect to plant next to Swiss chard.
2. Nitrogen-Fixing Friends for Leafy Growth
Since Swiss chard is a leafy green, it craves nitrogen to produce those big, glossy leaves you love to harvest.
You can plant legumes next to Swiss chard to naturally supply this essential nutrient.
Beans and peas have the remarkable ability to pull nitrogen from the air and store it in their roots.
As they grow, they release this nitrogen into the surrounding soil, feeding your Swiss chard.
This relationship is a perfect match because they also share similar water and sunlight needs.
Bush beans are an especially great choice because they stay compact and won’t shade your chard.
Simply plant a row of bush beans next to your Swiss chard and watch both thrive with minimal extra feeding.
This is an easy, organic way to boost your harvest without relying on synthetic fertilizers.
3. Root Vegetables That Share the Space Well
Root vegetables are some of the easiest things to plant next to Swiss chard since they occupy a different soil level.
While Swiss chard spreads its leaves up top, root crops grow down below, so they don’t compete for space.
Radishes are a classic companion because they grow quickly and help break up compacted soil.
They also act as a trap crop for leaf miners, drawing the pests away from your chard.
Carrots and beets are also excellent neighbors, as they have shallow roots that won’t disturb the chard’s root system.
These root vegetables also appreciate the shade that the broad chard leaves provide during hot summer months.
This mutual shading keeps the soil cooler and retains moisture, which is beneficial for everyone involved.
So, go ahead and interplant these with your Swiss chard for a productive and efficient use of garden space.
4. Bright Flowers to Attract Beneficial Insects
Don’t underestimate the power of beauty, because certain flowers are superheroes when planted next to Swiss chard.
Marigolds are famous for their ability to repel nematodes and other soil-borne pests.
Their bright, cheerful blooms also attract hoverflies and ladybugs that feast on aphids.
Nasturtiums are another fantastic flowering companion to plant next to Swiss chard.
These vibrant flowers act as a sacrificial trap crop, luring aphids away from your chard and onto themselves.
This keeps your Swiss chard clean and pest-free without any harmful pesticides.
Additionally, planting flowers like calendula and borage brings in pollinators that help the entire garden flourish.
These flowers make your vegetable patch look stunning while doing so much heavy lifting for your Swiss chard’s health.
What Not To Plant Next To Swiss Chard
Just as important as knowing what to plant next to Swiss chard is knowing which plants to keep far away.
Some plants are heavy feeders or allelopathic, meaning they release chemicals that inhibit the growth of nearby plants.
The biggest rivals for Swiss chard are other leafy greens from the same family, like spinach and beets.
Planting these together increases the risk of sharing the same diseases and pests, like leaf miners.
You should also avoid planting Swiss chard next to sunflowers, as they produce a chemical that stunts the growth of other plants.
Corn is not a good neighbor either, as it’s a heavy feeder and will steal too many nutrients from your chard.
Another plant to avoid is fennel, which is known for being a poor companion for almost everything in the garden.
By keeping these away, you ensure your Swiss chard has access to all the resources it needs without competition.
So, What Can You Plant Next To Swiss Chard?
You can plant a wonderful variety of herbs, root vegetables, and flowers next to Swiss chard to maximize your garden’s health.
The best plants to put next to Swiss chard include aromatic herbs like sage and mint for pest control, and root crops like radishes and carrots for smart space use.
Don’t forget to add nitrogen-fixing beans and pest-repelling marigolds to round out your perfect companion planting scheme.
Just be sure to avoid planting spinach, beets, sunflowers, and fennel next to your Swiss chard to prevent disease and nutrient competition.
With these tips, you can confidently plan your garden layout and watch your Swiss chard flourish like never before.
Happy gardening, and enjoy the bountiful harvest from your perfectly paired beds.
