What Can You Plant Next To Swiss Chard: The Top Companions

So, what can you plant next to Swiss chard? Plenty of options exist.

Here’s a breakdown of the best companions and how they help your chard thrive.

1. Root Vegetables Like Beets and Carrots

Root vegetables are fantastic neighbors for Swiss chard because they don’t compete for the same space above ground.

Swiss chard grows tall with broad leaves, while beets and carrots grow downward into the soil.

This means they won’t crowd each other out.

Beets also belong to the same family as chard, so they enjoy similar soil and watering conditions.

Carrots help break up the soil, which improves drainage and aeration for your chard’s shallow roots.

You can plant these root veggies in rows between your Swiss chard to maximize your garden bed.

2. Aromatic Herbs Like Dill and Mint

Planting herbs near Swiss chard is a smart move for natural pest control.

Dill attracts beneficial insects like ladybugs and lacewings, which feast on aphids that love to snack on chard leaves.

Mint has a strong scent that confuses and repels pests like flea beetles and cabbage worms.

Just be careful with mint, as it spreads aggressively, so plant it in a contained pot sunk into the ground.

Other great herbs to plant next to Swiss chard include rosemary, sage, and thyme.

These aromatic plants also improve the flavor of your chard and add diversity to your garden.

3. Flowers Like Marigolds and Nasturtiums

Flowers aren’t just pretty; they serve a serious purpose in the vegetable garden.

Marigolds are a top choice to plant next to Swiss chard because they release a chemical from their roots that kills nematodes in the soil.

They also attract hoverflies, which are natural predators of aphids.

Nasturtiums act as a trap crop, meaning they attract aphids away from your Swiss chard to themselves.

This sacrificial planting keeps your chard clean and pest-free.

Other good flower companions include calendula and sweet alyssum, which draw in pollinators that help your garden overall.

4. Nitrogen-Fixing Plants Like Bush Beans

Bush beans are an excellent companion because they add nitrogen back into the soil.

Swiss chard is a heavy feeder that loves nitrogen for its leafy growth.

When you plant bush beans next to Swiss chard, the beans take nitrogen from the air and convert it into a form the chard can use.

This natural fertilization process means you might not need to add as much compost or fertilizer.

Just avoid pole beans, as they can shade out your chard and compete for vertical space.

5. Alliums Like Onions and Garlic

Onions and garlic are incredible companions for Swiss chard because of their strong smell.

This scent deters many common pests, including slugs, snails, and leaf miners.

Leaf miners are particularly troublesome for chard, so planting alliums nearby acts as a camouflage.

The pungent aroma hides the chard’s scent from these flying pests.

Plus, onions and garlic have shallow roots, so they won’t disturb your chard’s root system.

You can easily interplant them in and around your chard patch.

What Not To Plant Next To Swiss Chard

Knowing what not to plant is just as important as knowing what to plant.

Your Swiss chard will suffer if placed near certain crops.

1. Other Leafy Greens Like Spinach

Avoid planting Swiss chard next to spinach and other leafy greens.

They compete for the same nutrients, especially nitrogen, which can stunt each other’s growth.

They also share the same pests, like leaf miners and aphids, making infestations spread quickly.

Planting them together creates a buffet for hungry insects and increases disease risk.

2. Sunflowers and Corn

Sunflowers and corn are heavy feeders that will compete with Swiss chard for water and nutrients.

They also grow tall, casting shade that can stunt your chard’s leaf production.

Swiss chard needs full sun to thrive, so avoid tall crops that block the light.

If you have limited space, keep these sun-loving giants away from your chard patch.

3. Cucumbers and Melons

Cucumbers and melons are also not ideal to plant next to Swiss chard.

They are heavy feeders and their sprawling vines can smother the lower leaves of your chard.

They also attract cucumber beetles, which can spread bacterial wilt disease to your chard.

It’s best to give these vine crops their own designated area in the garden.

How To Plan Your Garden Layout For Swiss Chard

Planning your layout properly ensures your Swiss chard gets the best companion benefits.

Here are simple tips for arranging your plants next to Swiss chard.

1. Use Interplanting for Space Efficiency

Interplanting means mixing your companion plants in the same row or bed.

For example, you can plant a row of Swiss chard, then a row of carrots next to it.

Alternate your chard with onions every few feet to maximize pest control.

This uses space effectively and creates a diverse, healthy ecosystem.

2. Consider Tall Plants on the North Side

If planting beans or other taller companions, place them on the north side of your chard.

This prevents them from casting shade on your chard, which prefers full sun.

Your chard will still get the nitrogen benefits from the beans while enjoying uninterrupted sunlight.

3. Rotate Your Crops Each Year

Don’t plant Swiss chard in the same spot year after year.

Crop rotation prevents the buildup of pests and diseases in the soil.

When planning what to plant next to Swiss chard, also think about what came before it.

Rotate with root crops or legumes to keep your soil healthy and productive.

So, What Can You Plant Next To Swiss Chard?

You can plant a wide variety of vegetables, herbs, and flowers next to Swiss chard to boost growth and deter pests.

Root vegetables, aromatic herbs, marigolds, bush beans, and alliums are all top choices for companions.

By avoiding spinach, sunflowers, and cucumbers, you’ll prevent competition and pest issues.

Planning your garden with these companions is a simple, organic way to ensure a healthy harvest.

What can you plant next to Swiss chard? The answer is a thriving, diverse garden full of beneficial partnerships.

Happy planting.
