Cucumber Companion Plants: Best Plants for Cucumber to Grow

cucumber companion planting

Cucumbers are a popular summer vegetable that can be eaten fresh or used in salads. They grow best when they are planted near other plants. 

When it comes to companion planting, cucumbers are lucky vegetables. They have a wide variety of plants that they can be grown with. 

These plants help improve the cucumber’s growth and health, but they also protect the cucumber from pests and diseases. 

This blog will explore some of the best plants to grow with cucumbers.

About Companion Planting

Companion planting is a form of gardening where plants are grown together for the benefit of each other. 

Companion plants can help to improve soil quality, repel pests, and attract beneficial insects by the farmers and gardeners. 

Some companion plants are edible, which means you can use them in the garden and the kitchen.

Benefits of Companion Planting

As mentioned before, companion planting is simply the act of planting two or more plants together for the mutual benefit of each other. 

Most gardeners companion plants without even realizing it, as many plants naturally grow well together and help protect each other from pests and diseases. 

But there are also specific companion planting combinations that have been proven to be incredibly beneficial.

One of the main benefits of companion planting is that it can help improve soil health. 

When different types of plants are grown together, they provide a variety of nutrients and organic matter to the soil, which helps keep it healthy and fertile. 

It is essential in vegetable gardens, where nutrient-rich soil is necessary for healthy plants.

Another benefit of companion planting is that it can help reduce pest and disease problems. 

When different plants are grown together, they create a “natural barrier” against pests and diseases.

Companion Plants for Cucumber

When planning a garden, it is essential to consider companion plants to make the most of your space. 

Companion planting for cucumbers can help improve pollination, deter pests, and improve growth and yield.

Here are the five common plants that you can plant beside your cucumber:


Corn stalks may be used as natural trellises for vining cucumbers, which is a terrific way to save space and get the most out of your garden.

Make sure you use a cucumber variety like pickled cucumbers that stay small and light.

Your corn stalks will not be able to support them otherwise.

Cucumber vines will act as a natural mulch beneath your corn stalks, storing moisture and keeping weeds at bay in exchange for your help.

Root Vegetables

Cucumber plants only have one large taproot, while the remaining of their roots are narrow and shallow, extending about six to twelve inches in any direction.

It means that planting cucumbers near root vegetables like carrots, parsnips, radishes, and turnips won’t interfere with their growth because root veggies develop primarily beneath the soil and use up an area that cucumbers don’t.

Radishes may also discourage cucumber beetles, a cucumber patch’s deadliest adversary.


Legumes, such as sugar snap peas and green beans, are excellent companion plants for cucumbers because they offer much-needed nitrogen to the soil.


It is a popular aromatic herb to grow in a home garden. It attracts helpful insects such as pollinators and parasitic wasps, which help pollinate cucumbers and keep other garden pests at bay.

Dill is also said to improve the flavor of mature cucumbers by many gardeners.

However, you should use other aromatic herbs with caution. Other herb plants with strong scents and flavors, such as sage and mint, may alter the taste of your cucumbers.


Sunflower stalks may be used as natural trellises for vining cucumbers, similar to corn stalks, which is a terrific method to save space and maximize garden efficiency.

Use a cucumber kind that stays small and light, like pickled cucumbers; otherwise, your sunflowers will struggle to support them.

Incompatible Plants for Cucumber

Some plants can grow well together, but some seem to hate each other.

They are called Incompatible Garden Plants, a group of plants that cannot plant together because they cause an effect when they grow in the same soil.

There are several reasons why they can’t go well. Some plants produce chemicals that can affect the growth of other plants; they are known as Allelopathic Plants, while other plants are vulnerable to pests and parasites that can be harmful to others.

Here are the five common incompatible plants that cannot grow in your cucumber:


Cucumber and melon plants are both vining plants that stretch across the ground, and the same pests also plague them. 

When cucumbers and melons are planted together, they will attract pests in higher numbers.


Potatoes are heavy feeders and drink a lot of water, so they’ll fight for the same nutrients if they’re planted close to cucumbers.

Furthermore, cucumbers may raise the risk of your potatoes contracting disease. Plant cucumbers and potatoes far apart in your yard if you want them to grow together.


Fennel is a garden crop that doesn’t mix well with most other vegetable garden plants. Thus, most home gardeners avoid it.

While it can attract helpful insects, it can also hinder the growth of most other plants, slowing or even killing them.


Apart from dill, many aromatic herbs in the garden wreak havoc on cucumber plants, with sage being the worst offender.

Because cucumbers have such a delicate flavor, overpowering fragrant plants such as sage, mint, and hyssop may alter the flavor profile when planted too close to cucumbers.


Cucumbers have a complicated connection with brassica plants like brussels sprouts, cabbage, cauliflower, kale, and kohlrabi.

While many gardeners believe that planting brassicas near cucumbers will boost their growth, brassicas are often very water-hungry plants. 

If planted near cucumbers, they may fight for water in the soil, thereby inhibiting their growth.

Final Note

Companion plants are a great way to improve the growth and yield of cucumbers, not even for cucumber but also the other vegetable plants.

Some of the best plants with cucumbers include corn, root vegetables, and legumes. 

By using companion plants, gardeners can increase the productivity of their gardens while also enjoying the benefits that these plants provide.
