What NOT to Plant Next to Swiss Chard

Swiss chard does not grow well with all plants. This is because some plants attract pests or compete for nutrients with the chard plants. Do you know what these plants are?

First, you should avoid sunflowers which are allelopathic. They release chemicals from their leaves, stems, and roots that harm nearby plants. These chemicals hinder seed germination. They also cause stunt growth in seedlings of many plants.  

Second, experts advise that you should avoid growing the Swiss chard with members of the goosefoot family. Examples of such plants are quinoa, beets, amaranth, and spinach.

This advice helps to control pests and diseases. Plants in the goosefoot family usually attract the same pests and are predisposed to similar pathogens. If a pest has an affinity for one type of vegetable, it usually attacks related vegetables.

Therefore, if you spread out members of the same family, it will help slow down pests. You can also slow down the spread of diseases.

Alternatively, you can simplify crop rotation by grouping members of the same family together but creating buffers between them. You can use alliums, lettuce, herbs, or marigolds to create buffers, as they confuse and slow down the pests.   

Additionally, traditional literature claims corn and potatoes are not great companions for Swiss chard. Because they are voracious feeders, they will compete for nitrogen in the soil. 

Furthermore, cucurbit family members, like cucumbers, melons, squash, and gourds, also make bad companions for chards. This is because the trailing vines of cucurbits can overwhelm, strangle and cover the Swiss chards. Moreover, the cucurbits are heavy feeders and will take away nutrients from the soil.

Here are the plants you should not plant next to Swiss chard:

Beets, quinoa, and potatoesThese companions are unsuitable because they attract pests.

Recommended Swiss Chard Companion Plants

As you look for what to plant next to Swiss chard? It is important to remember that the Swiss chard is a light feeder. Moreover, it is not prone to pest and disease problems.

As a result, it is usually an excellent companion for many plants. On the other hand, there are many different types of plants that can be good companions for the Swiss chord.

While there are many options for Swiss chard companions, here are seven of the top good neighbors to start with:


Alliums have numerous benefits as companion plants. For example, a strong odor makes alliums like shallots, leeks, onions, garlic, and shives usually help to repel undesirable insects. On the other hand, when they bloom, they attract helpful insects like bees, wasps, and hoverflies.

Many people love chives because of their beautiful globe-shaped flower heads, which are effortless to harvest. Furthermore, they pack a strong punch of garlicky aroma. They are also easy to grow from seed.

Chives are also beneficial because they bloom early, providing food sources for beneficial predatory insects that help reduce pest populations.


Annual Flowers

A wide range of annual flowers makes excellent Swiss chard companions. Some Swiss chard varieties are very colorful that they would look out of place in your flower bed.

Marigolds are useful garden neighbors because they can repel root-knot nematodes and pests. Nasturtiums are excellent garden companions because their flowers usually attract helpful insects. Also, their leaves have a strong scent that repels certain pests, including aphids.

The sweet alyssum is another great companion for several reasons. For example, it provides ground cover that helps to keep weeds at bay. Moreover, it shades the soil around the plants. Their sweet alyssum flowers have a fragrance that attracts helpful insects, including hoverflies, that help keep aphid populations in check.

Consider the ‘Carpet of Snow,’ a sweet asylum variety providing excellent ground cover. It usually grows up to five inches tall, producing numerous small flowers.


Many companion planting literature cites cabbage as a suitable Swiss chard companion. Other cabbage family members, such as radishes, kale, turnips, broccoli, and Kohlrabi, are also good companions.

One of the main benefits of cabbage is that it has a shallow root system, while the Swiss chard roots go relatively deeper. In the same way, you don’t want the plant portions above the ground to fight for space. It will help if the underground portions are not fighting for space also. Grouping plants having complementary root depths is a popular strategy in companion planting. 


Celery is a compact plant that makes an excellent Swiss chard companion. Its properties above and below ground are friendly to the Swiss chard. Celery is a good companion if you grow it as a fall crop.

Moreover, the cool autumn weather sweetens both plants. Many gardeners usually buy celery as the nursery starts to transplant them into their gardens. However, you can only grow celery from seed, allowing you to choose from different varieties.



Companion planting literature claims that not all herbs are great Swiss chard companion plants. For example, many gardeners claim that dill or cilantro make great companions for Swiss chard.

Some of its benefits include attracting beneficial insects like hoverflies and wasps. Additionally, lavender, lovage, and marjoram also make excellent companions for chard. However, mint seems to have the best reputation of all herbs.

If you allow the mint to bloom, it will attract helpful insects thanks to its numerous flowers. The plant also repels flea beetles, a common pest that targets the Swiss chard.

Furthermore, the fragrant compounds in mint also mask the smell of other plants. This makes it challenging for pests to locate the host plants. But, if you choose to grow mint as a Swiss chard companion, keep it in a container. This approach will help you prevent it from taking over your entire vegetable patch.

There are wide mint varieties available. But peppermint is preferable because it has a fresh taste, is clean, and has cooling properties. Moreover, mint is a wonderful herb to have in your garden. You can use it to make homemade iced herbal tea.


Legumes are great companion plants for Swiss chard because it helps fix nitrogen in the soil. In this regard, peas and bush beans are normally the best companions for Swiss chard. Besides, most companion planting experts claim that pole beans are a good choice.

This is because of the crop’s towering nature when you trellis it. Peas are also trellised but die back in late spring or early summer. This is usually when pole beans are taking off and can potentially shade your Swiss chard crop.

For this reason, experts suggest you should not include pole beans as a garden companion. However, there is a workaround. For example, you can plant your Swiss chard on the pole bean’s trellis. This approach ensures your Swiss chard gets full sun.

Other legumes you can try out as Swiss chard companions include garbanzo beans and fava beans. In the meantime, you can stick with bush beans as the nitrogen-fixing companion for your Swiss chords.

Lettuce makes an excellent Swiss chord companion. Growing these leafy veggies side by side helps maximize your garden’s space. Moreover, it makes your salad harvests effortless.

Besides that, lettuce has a shallow system meaning it will not compete with your Swiss chard for underground space. Additionally, using lettuce as a garden companion is helpful because it provides living mulch. It covers the soil preventing weeds from popping up. Furthermore, it slows erosion and water evaporation.

There are numerous lettuce varieties that are both beautiful and delicious. Some types are better at offering living mulch. In this sense, consider picking a combination that has a more spreading growth habit. One famous example is Batavian. Like Romaine, avoid lettuce varieties with an upright growth habit.
