What Grows Well With Cucumbers: Companion Planting Guide

Legumes: Peas, Beans, Lentils

Cucumbers are known for their delicious crunch and refreshing taste, and they can thrive when planted alongside legumes such as peas, beans, and lentils. These legumes are nitrogen-fixing plants, meaning they have the ability to convert nitrogen from the air into a form that can be absorbed by plants. Cucumbers, like many other vegetables, require a good amount of nitrogen for healthy growth, making legumes excellent companion plants.

Additionally, legumes help improve soil fertility by increasing its nitrogen content. They do this by forming a symbiotic relationship with nitrogen-fixing bacteria, which colonize their root nodules. These bacteria convert atmospheric nitrogen into ammonium, a form that plants can utilize. By planting cucumbers next to legumes, you can ensure that your cucumbers receive a sufficient supply of nitrogen, leading to vigorous growth and abundant yields.

It is worth mentioning that cucumbers and legumes have similar sunlight and water requirements, making them compatible companions. Both thrive in full sun and well-drained soil. To maximize the benefits of this companion planting strategy, consider providing support structures such as trellises or stakes for both the cucumbers and legumes to climb on, as this will optimize space utilization and allow for better air circulation, reducing the risk of disease.

• Cucumbers and legumes are compatible companion plants
• Legumes are nitrogen-fixing plants that convert atmospheric nitrogen
• Symbiotic relationship with nitrogen-fixing bacteria improves soil fertility
• Cucumbers and legumes have similar sunlight and water requirements
• Use trellises or stakes to support climbing cucumbers and legumes.

Corn

Another excellent companion plant for cucumbers is corn. The tall stalks of corn provide a natural trellis for cucumbers to climb on, saving space in your garden and creating a visually appealing combination. This method is known as vertical gardening and is favored by many gardeners who want to maximize their yields in limited space.

Cucumbers benefit from the shade provided by corn, especially during hot summer months when excessive heat can stress the plants. The shade from the corn plants helps to regulate the temperature, keeping the cucumber vines cool and preventing them from wilting. In return, cucumbers can provide ground cover, shading the soil around the corn plants and helping to retain soil moisture, which is essential for the healthy growth of corn.

When intercropping cucumbers and corn, it is important to ensure proper spacing. Plant the corn rows in the north-south direction to avoid blocking the sunlight for the cucumbers. Additionally, consider planting the cucumbers on the north side of the corn rows, allowing them to receive full sun exposure while benefiting from the shade cast by the corn.

Root Vegetables: Radishes, Beets, Carrots, Garlic

Root vegetables such as radishes, beets, carrots, and garlic make excellent companion plants for cucumbers. These underground crops have shallow root systems that do not compete heavily with the cucumbers for nutrients and water. Additionally, the root vegetables tend to break up and aerate the soil, which can benefit the cucumbers by promoting better drainage and root development.

Furthermore, certain root vegetables, like radishes and garlic, have natural pest-repellent properties. Radishes, for example, can help deter pests such as cucumber beetles, aphids, and squash bugs due to their pungent smell. Garlic has similar pest-repellent qualities and can ward off aphids and various pests that commonly plague cucumber plants.

When companion planting cucumbers with root vegetables, consider the space requirements of each crop. Radishes, for instance, have a quick growth cycle and can be planted in between the cucumber rows. As radishes mature and are harvested, there will be more room for the cucumbers to spread out. Be mindful of the spreading nature of cucumbers and avoid crowding them too closely with the root vegetables to prevent shading and competition for resources.

Select Flowers: Marigolds, Nasturtiums, Sunflowers

Select flowers such as marigolds, nasturtiums, and sunflowers can be beneficial companions for cucumbers. These flowers not only add beauty to your garden, but they also serve important purposes in terms of pest management and soil improvement.

• Marigolds repel insects that may harm cucumbers due to their strong aroma. By planting marigolds near cucumbers, pests like aphids, cucumber beetles, and nematodes are deterred, reducing the likelihood of infestations. Marigolds also produce a chemical that inhibits the growth of certain soil-borne pathogens, providing protection against diseases.

• Nasturtiums act as trap crops for cucumbers. They attract pests and draw them away from the cucumber plants. Aphids, for example, are more likely to concentrate their damage on nasturtiums instead of the cucumbers.

• Sunflowers provide shade and support for cucumber vines. They act as a natural trellis, similar to corn, allowing cucumbers to climb. The large leaves of sunflowers create shade, protecting the cucumbers from excessive sun exposure. This shade helps reduce water stress and prevents overheating.

When planting flowers with cucumbers, ensure adequate spacing for both crops to thrive. Plant marigolds, nasturtiums, or sunflowers along the edges of the cucumber patch or interspersed throughout the cucumber rows.

Select Herbs: Dill, Oregano

Dill and oregano are two popular herbs that can enhance the growth and flavor of cucumbers when used as companion plants. These herbs attract beneficial insects and repel pests, creating a healthy and harmonious environment for your cucumbers.

Dill is particularly attractive to beneficial insects such as ladybugs, lacewings, and hoverflies, which feed on common cucumber pests like aphids and mites. By planting dill near cucumbers, you can attract these beneficial insects to your garden and naturally control pest populations.

Oregano, with its strong aroma, acts as a natural insect repellent and can deter pests that may damage cucumbers. Aphids, in particular, are known to steer clear of oregano. Furthermore, oregano has been shown to have antimicrobial properties, which can help prevent the spread of diseases among cucumber plants.

To incorporate dill and oregano into your cucumber planting scheme, you can plant them either near the cucumber vines or in close proximity within the same garden bed. Ensure that the herbs receive enough sunlight while avoiding shading the cucumbers.

Tip: Consider using a mulch around the plants to help retain moisture and suppress weeds.

• Plant dill near cucumbers to attract beneficial insects
• Use oregano as a natural insect repellent for cucumber pests
• Incorporate dill and oregano near cucumber vines or in the same garden bed
• Ensure sufficient sunlight for herbs without shading the cucumbers
• Consider using mulch around the plants for moisture retention and weed suppression

Frequently Asked Questions

What should cucumbers be planted next to?

Cucumbers should be planted next to nitrogen-fixing plants such as peas, corn, beans, and lentils. These plants have root systems that increase nitrogen in the soil, which is beneficial for the growth of cucumbers. In addition, mature corn stalks can serve as natural support for climbing cucumbers, and they also provide much-needed shade in areas that receive intense sunlight.

What is best to plant cucumbers in?

The best choice for planting cucumbers would be to create raised beds with well-drained, slightly acidic soil. Forming raised beds not only promotes good drainage but also helps to retain moisture. To further enhance the soil quality, incorporating well-rotted manure or compost during spring or fall will provide the necessary nutrients for healthy cucumber growth. By following these guidelines, you can optimize yield and quality while cultivating your cucumber plants.

What is the best support for cucumber plants?

The most suitable support for cucumber plants would be wire cages or trellises. These structures allow the cucumber vines to climb and utilize their tendrils effectively. With a wire cage or trellis, the cucumbers are kept off the ground, making them easier to pick and preventing them from getting dirty. Overall, utilizing wire cages or trellises as support for cucumber plants ensures efficient growth and facilitates convenient harvest.

Do cucumbers need two plants?

No, cucumbers do not need two plants for pollination. Male and female flowers can be found on the same plant, allowing for self-pollination. However, the presence of a nearby plant can benefit pollination as it increases the chances of attracting local bees, which play a crucial role in the process.
