Plants, like humans, thrive when good companions surround them. And companion planting is a part of organic cultivation. Companion planting is done for various reasons, including repelling pests, improving the flavor of produce, attracting pollinators, and so on. Plants can reap the benefits mentioned above when paired with suitable companions. On the other hand, some plants do not get along. When planted in pairs, they act as obnoxious and often destructive neighbors to one another.

Top- 8 Bok Choy Companion Plants

Welcome to the crux of the article! Here, we will specifically list companion plants beneficial to Bok Choy. This section has been divided into two sections. These categories will help you understand companion plants that aid in pest control and those that attract pollinators.

Celery is known as the Brassica family’s best friend. Not only for humans but also for Bok Choy, this biennial vegetable is renowned for its “healthy crunch.” This crop helps keep the cabbage worm at bay when planted near Bok Choy.

Planting Bok Choy and Nasturtium in your vegetable garden can produce a stunning color display. Nasturtiums keep cabbage loopers, squash bugs, and whiteflies away from Bok Choy as well. These flowers are also edible. As a result, Nasturtiums will provide you with two benefits: an insect repellent and a flavorful crop.

These flowering plants can also be planted ahead of your host plant to act as trap plants for aphids, cabbage worms, and flea beetles. When the nasturtiums are completely infested, pull them up and place them in a sealed plastic bag for disposal.

3. Mint

Aromatic herbs, such as mint, offer various advantages to Bok choy as companion plants. For example, their fragrance camouflages the host plant’s odor and distracts harmful pests. However, remember that mint is a fast-growing plant that, if not controlled, can choke out neighboring plants. Planting mint in containers and placing them near Bok Choy would thus be a better and more practical option. Also, keep an eye on aphid infestation, as this pest is attracted to mint.

Borage is an excellent companion plant for your vegetable garden. When planted near Bok Choy, Borage helps keep cabbage worms at bay. Furthermore, predatory insects such as hoverflies and lacewings use borage leaves as a habitat.

Among the many advantages of borage is its ability to make adjoining crops more resistant to stressors. Large leaves also serve as living mulch for your host plant and enrich the soil with nitrogen and other nutrients.

3. Cilantro

Cilantro is an excellent companion plant for luring beneficial predatory insects such as lacewings, ladybugs, hoverflies, etc. These predatory insects, in turn, prey on Bok Choy pests such as aphids and cabbage maggots.

Why Pair Bok Choy With Companion Plants?

Have you ever thought about why you should use companion planting as a gardener? There could be several reasons for this organic gardening science. However, in this section, we will investigate the reasons for using companion planting with Bok Choy.

1. Pest Repellation

Keep in mind that companion plants should be chosen based on the pests that most bother your Bok Choy.

2. Enriching Soil

Bok Choy, as previously stated, prefers highly fertile soil and is a heavy feeding crop. Therefore, choosing leguminous plants, such as bush beans can help enrich the soil with nitrogen. This, in turn, can help Bok Choy get more soil nutrition, allowing it to thrive better.

3. Overall Good Health

Plant your Bok Choy with garden buddies like beets, carrots, chards, cucumbers, and so on to ensure its overall health. Combining this crop with flavor-enhancing companions, such as garlic, can also be beneficial.

Plants That Do Not Go Well With Bok Choy

After you’ve mastered the friendly plants, it’s time to focus on the plants that are a no-no for Bok Choy. Keep in mind that not all plants make good peers. So, the following list will teach you about the incorrect Bok Choy companion plants and why you should avoid them.

Let us begin with the nightshades!

Plants in the nightshade family are susceptible to verticillium wilt. So, combining your Bok Choy with tomatoes, eggplants, and peppers increases the likelihood of your host plant becoming infected with this fungal disease. It’s akin to inviting disease into your garden.

2. Other Brassicas

It stands to reason that all Brassica plants will be susceptible to the same diseases and attract similar pests. This could result in a pest infestation. In addition, their nutritional needs would be the same. As a result, if they are planted together, they will compete for soil nutrition, resulting in stunted growth and even death.

3. Strawberries

Strawberries should be planted separately from all Brassica family crops. These berries produce chemicals that can inhibit the growth of Bok Choy. In addition, strawberries, like Bok Choy, are also heavy feeders. Planting two heavy feeders together would result in intense competition for nutrition. Both plants’ growth may be hampered as a result.

4. Sunflower

One of the primary reasons for avoiding sunflowers is their height. Sunflowers grow pretty tall, and they attract sunlight towards them. This could result in your Bok Choy getting permanent shade and keeping starved for sun exposure.


Here are the related questions and answers to keep you further abreast about the Bok Choy plant.

1. Do I need to maintain a minimum distance between host and companion plants?

Ans. Yes, maintain at least 1-6 inches of spacing while planting Bok Choy in a row or with any companion plant. The spacing must also be dependent on the spread of the companion plant. Be cautious not to overcrowd your garden.

2. Which pest bothers Bok Choy the most?

Ans. Some pests that tend to affect Bok Choy include
• Aphids
• Cabbage loopers
• Cabbage moth
• Slug 
• Snails
• Tarnished plant bugs

3. Is zucchini a good companion plant for Bok Choy?

Ans. Zucchini may not be an ideal choice to be planted with Bok Choy. We say so because this crop is a heavy feeder. So if grown together, both Bok Choy and zucchini would compete for nutrition.

4. Are aromatic herbs good to be paired with Bok Choy?

Ans. Yes, aromatic herbs like mint, thyme, chamomile, and lavender, among others, can be paired with Bok Choy. The fragrance of these herbs will lure beneficial insects while acting as camouflage for harmful pests.

5. Is corn a beneficial companion plant for Bok Choy?

Ans. Corns are heavy feeders and grow tall. So growing corns near Bok Choy would mean a heavy competition for nutrition and the creation of permanent shade. So, pairing these two crops is a complete NO.
