Companion planting offers a multitude of benefits, such as weed control, improved pollination rates, and natural support for climbing vines. In this guide, we will introduce you to the best companion plants for cucumbers, highlighting their unique advantages. Discover the joys of companion planting and watch your cucumber crop thrive!

The Best Companion Plants for Cucumbers

Flowers, herbs, and vegetables can all work harmoniously alongside cucumbers. The key is to find plants that share similar growing conditions and offer additional benefits to cucumbers. Below, we present a selection of the most effective cucumber companions and reveal what sets each plant apart.

1. Beans and Peas

Legumes, such as beans and peas, prove to be excellent companions for cucumbers. These plants have the remarkable ability to fix nitrogen in the soil, enriching the earth around cucumber plants and supporting vine growth. Furthermore, climbing varieties of pole beans and peas can utilize the same trellis as cucumbers, optimizing trellising space.

Consider planting peas in the spring and cucumbers in the same area later in the season. Alternatively, sow legumes and cucumbers simultaneously, taking advantage of their shared trellis. Legume cover crops, like field peas, can also be grown at the end of the season, preparing the soil for spring planting.

2. Corn

While corn may not be an obvious companion for cucumbers due to its heavy nutrient requirements, these two plants can complement each other beautifully. The tall cornstalks provide shade for cucumber plants, and cucumber vines can employ corn as a natural trellis.

For successful trellising, select cucumber varieties with smaller fruits, like pickling cucumbers or cucamelons. These varieties won’t overwhelm the cornstalks with their weight. Embrace the symbiotic relationship between corn and cucumbers for a lush and productive garden.

3. Marigolds

Marigolds are highly esteemed companion plants in vegetable gardens as they possess pest-repellent properties. While some gardeners claim marigolds deter rabbits, further research is needed to confirm this. However, marigolds are known to control nematode populations and attract beneficial insects, such as ladybugs and lacewings.

Benefit from marigolds’ pest protection and adorn your garden with their vibrant orange, yellow, and red flowers. Marigolds bring both beauty and practicality to your vegetable patch.

4. Radishes

For early-season gardening, consider planting radishes alongside cucumbers to maximize your garden space. Radishes grow rapidly and can be harvested before cucumbers ripen. Compact and low-growing, radishes fit effortlessly beneath established cucumber vines.

Radishes not only provide an additional harvest but also act as a valuable crop protection tool. They can serve as “trap crops” for flea beetles and other troublesome insects. Embrace the versatility of radishes and enjoy their benefits alongside cucumbers.

5. Oregano

When it comes to natural pest protection, aromatic herbs like oregano shine. Oregano successfully repels various pests and requires minimal care once established. By interplanting oregano with cucumbers, you can keep your garden low-maintenance and safeguard your cucumber vines.

Explore different recipes that combine oregano and cucumbers, such as homemade oregano pickles or fresh garden salads. Oregano’s flowering stage will attract beneficial insects to your garden, aiding in pollination.

6. Alliums

The allium family, including garlic, chives, onions, shallots, and leeks, offer more than just their distinctive flavors. These plants emit a strong fragrance due to their high sulfur content, making them excellent pest deterrents. Alliums can repel aphids, Japanese beetles, deer, rabbits, and cabbage loopers.

Alliums make ideal cucumber companions due to their low-growing nature, which prevents competition for space and light. Additionally, garlic and onions are commonly used in pickling recipes, complementing the cucumbers perfectly.

7. Beets

Maximize your garden’s potential by planting beets alongside cucumbers. Beets grow quickly and can be sown in succession with cucumbers, providing an additional harvest before cucumbers mature. Their compact nature allows them to thrive even when planted beneath cucumber vines.

Beets contribute to soil aeration, thanks to their long taproots. They appreciate the moisture cucumbers require and improve garden soil by loosening it and counteracting compaction.

8. Borage

As a natural pollinator magnet, borage pairs exceptionally well with cucumbers. By planting borage near cucumber vines, you attract more pollinators, resulting in a larger cucumber harvest. The blooms also entice beneficial insects, which effectively control pests.

Borage’s edible flowers and leaves offer culinary opportunities. Experiment with flavors and textures by combining borage and cucumbers in fresh garden salads or pickling recipes.

9. Nasturtium

If pest control is a priority, consider growing nasturtiums alongside cucumbers. Similar to marigolds, nasturtiums repel pests and act as “trap crops” for aphids and whiteflies. Nasturtiums also draw pollinators to your garden and provide vibrant blooms that add color to your vegetable patch.

Embrace the versatility of nasturtiums by pickling their edible seeds or using them as salad toppers and garnishes. These beautiful flowers enhance both your culinary creations and your garden’s visual appeal.

10. Lettuce

Lettuce is a popular companion plant for various vegetables due to its non-invasive growth habit and ability to thrive in small spaces. By interplanting lettuce beneath cucumber trellises, you can optimize your growing area and enjoy an abundant vegetable harvest. Lettuce benefits from the shade cast by cucumbers, reducing bolting.

Lettuce pairs splendidly with cucumbers in various dishes and can be grown in containers alongside container-grown cucumbers. Extend your harvest by slowing down the bolting process through strategic companion planting.

11. Dill

Cucumbers and dill form a natural alliance, especially if you enjoy making homemade dill pickles. Dill attracts predatory wasps and other beneficial insects that feed on cucumber pests. Embrace dill’s tendency to bolt, as its flowering stage attracts beneficial insects and serves as a vital food source for swallowtail butterfly caterpillars.

Be mindful of dill’s bolting tendencies and ensure you have surplus plants for caterpillars to enjoy. Delight in the harmonious partnership between dill and cucumbers.

12. Calendula

While often referred to as “pot marigold,” calendula possesses unique properties separate from marigolds. Calendula, like marigolds, attracts pollinators and beneficial insects, such as ladybugs and lacewings. Enjoy the multitude of benefits calendula offers to cucumber plants.

Beyond its companionship, calendula serves as a medicinal herb, ornamental plant, and stunning cut flower. The flowers can also be used to create homemade fabric dyes.

13. Carrots

Similar to beets and radishes, carrots are an excellent choice for companion planting with cucumbers. These root vegetables occupy minimal space when grown alongside cucumber vines, enhancing your garden’s harvest potential. Carrots aerate the soil with their long taproots and won’t hinder cucumber growth.

Carrots and cucumbers complement each other in various recipes, granting you the freshest ingredients for your culinary adventures. Explore the versatility of carrots and savor their pickling potential.

14. Sweet Alyssum

Attracting pollinators to your cucumber patch is crucial for a successful harvest. Sweet alyssum serves as an excellent pollinator plant, drawing bees, butterflies, and other beneficial insects to your garden. Its compact size allows it to thrive beneath cucumber vines or in containers near your vegetable garden.

Embrace the beauty and functionality of sweet alyssum as it contributes to pollination and keeps pests at bay. Enhance your garden with these charming flowers.

15. Sunflowers

Sunflowers not only captivate with their large flower heads but also attract pollinators and beneficial insects. Their sturdy stems can serve as natural trellises for cucumber vines, akin to cornstalks. Opt for smaller cucumber varieties to ensure optimal trellising success.

If the tall stature of sunflowers concerns you, consider planting dwarf varieties. These smaller flowers offer the same benefits while maintaining a manageable height of around 1 to 2 feet.
