Benefits of using companion plants in cucumber farming

Cucumber farming as earlier explained can benefit a great deal from the use of companion plants.

Below are some of the benefits of using companion plants in the growing of cucumbers:

Enrichment of the soil

Some companion plants like beans, cowpea and other leguminous plants can fix nitrogen into the soil.

Nitrogen is one of the macro nutrients needed by plants. Nitrogen can improve the growth of the cucumber plant during the vegetative stage and also enhance the photosynthetic ability of the cucumber plant.

Tilling of some companion plants into the soil can also improve the microbial activities n the soil and improve the texture and cation exchange capacity of the soil.

Enhanced Pollination

Bees are some of the most prolific pollinators in farming. Some crops like marigold and sunflower attract a lot of bees and other pollinators to the field.

The colourful flowers of sunflower and marigold attract a lot of bees.

Pollination enables flowers to turn to fruits. In the case of cucumbers, the enhanced pollination of the flowers can lead to improved yield and better profitability.

Weed Control

Some companion plants can be used to prevent weeds in the growing of cucumbers. Some companion plants can occupy the space weeds would have occupied. This can have the effects of plastic mulches.

Pest Control

Do you know that companion plants like marigold can repel insects and kill soil nematodes? Marigold has a unique scent that repels pests especially beetles and insects which may want to attack the main crop.

Burying and tilling marigold in the soil can also kill the nematodes in the soil. Nematode is a harmful pest that deters plants from extracting water and nutrients from the soil.


Some companion plants like corn can serve as stakes or trellises for some crops.

Corn plant for example can act as a stake for cucumber plants when the cucumber plants are at the early stage.

Effects of crop rotation

The use of companion plants mimics the effects of crop rotation as no single crop is planted on the soil for a long time.

Crop rotation prevents the build-up of pests and diseases. Crop rotation is important in the growing of cucumbers.

Some cucumber companion plants in Nigeria

The following are some of the companion plants you can grow alongside cucumber plants in Nigeria:


This is leguminous crop called beans in Nigeria.  In Nigeria, there are two types of cowpea namely the red beans and the white beans.

Cowpea fixes essential nitrogen in the soil. Nitrogen is one of the macro nutrients needed for the growing of crops. Nitrogen ensures the vegetative growth of plants and also positively impacts the process of photosynthesis.

With more nitrogen in the soil, lesser quantity of nitrogen fertilizer will be used for cucumber farming.

Cowpea can be a fantastic companion plant for cucumber.


Corn also called Maize in Nigeria is one of the most cultivated crops in Nigeria. Go to any place in Nigeria and you are likely to see more corn farmers than other crops farmers.

Maize can be a good companion plant for cucumber plants. There are some benefits of planting corn as a companion plant to cucumbers.

With celery as a companion plant, some of the pests that affect cucumber plants can be repelled.

Marigold is one of the most popular cucumber companion plants. This is due to its ability of wading off pests from cucumber plants.

Marigold also helps in defeating nematodes which are harmful soil based pests.

Marigold can surely address some of the mistakes in cucumber farming.

A case study of a farmer who used companion plants with his main cucumber crop

Tunde, one of our customers is a time tested cucumber farmer; he has planted cucumber for several years.

Few weeks ago, Tunde tested the use of companion plants with the cultivation of cucumber. He planted some marigold with his main crop which is cucumber.

Tunde was able to spend 40% less on purchase of pesticides. He also realized that there was lesser pests and disease pressure on his cucumber plants.

The growing of cucumbers can be a profitable thing to do; having companion plants with your cucumber crop can make cucumber farming even more profitable.
