Maximizing Cucumber Growth with Companion Plants

Are you looking to enhance your cucumber garden? One way to achieve healthy and bountiful cucumber plants is by incorporating companion planting. Companion planting is a tried-and-true practice that involves strategically growing different plants together to optimize the health and productivity of your vegetable garden. While this technique dates back centuries, it continues to be a valuable approach for modern gardeners. In this guide, we will explore the concept of companion planting and discover the best companion plants for cucumbers.

Understanding Companion Planting

Companion planting revolves around the idea that certain plants, when grown together, can form symbiotic relationships that benefit one another. Each plant brings unique strengths that can improve the overall life and growth of neighboring plants. By identifying suitable plant pairings, you can create an environment that promotes optimal growth and enhances the flavor of your vegetables.

For example, indigenous communities used to interplant corn, squash, and green beans together. This combination enhanced biodiversity in their gardens. The beans would climb the cornstalks, providing nitrogen to the other plants. The squash would offer shade, reducing weeds and deterring pests. This traditional practice exemplifies the advantages of companion planting.

Beyond promoting growth, companion planting also aids in repelling pests, attracting beneficial insects, and improving pollination. Certain plants can deter pests or trap unwanted insects, while others attract pollinators and beneficial bugs. Additionally, companion plants can act as support structures, provide shade, or act as ground covers to reduce weeds and conserve moisture in the soil.

Excellent Companion Plants for Cucumbers

When selecting companion plants for your cucumbers, consider your specific goals and challenges. If you’re dealing with particular pests, choose plants that repel or attract beneficial insects accordingly. Here is a selection of companion plants that work well with cucumbers:


Cucumber companion plants

  • Marigolds, calendula, sunflowers, and tansy repel pests while attracting beneficial insects.
  • Nasturtiums repel cucumber beetles and thrips, improving the flavor of cucumbers.
  • Cosmos attracts parasitic wasps, which help control aphids, cucumber beetles, and squash bugs.
  • Buckwheat and cowpeas attract beetle predators that reduce pest populations.
  • Pansy, nasturtiums, and radish deter the cucumber beetle.


  • Bush beans, fava beans, pole beans, peas, and lentils fix nitrogen in the soil, benefiting cucumber plants.
  • These legumes also provide shade to cucumbers while reducing weeds and conserving soil moisture.

Root Vegetables

  • Carrots, onions, rutabaga, beets, radishes, turnips, and parsnips grow well alongside cucumbers.
  • Radishes repel rust flies and beetles, while cucumbers enhance radish growth.


  • Dill attracts ladybugs and pollinators while repelling spider mites.
  • Catnip, oregano, and chives help control insect pests.
  • Summer savory reduces the spread of cucumber beetles.

Other Crops

  • Leafy greens like spinach and lettuce thrive in the shade provided by cucumbers.
  • Tomatoes, eggplants, and peppers make excellent companions due to their similar watering needs and warm-season requirements.
  • Corn and sunflowers act as trellises for cucumber vines, provided you use a smaller cucumber variety that won’t overload them.

What Not to Plant with Cucumbers

Fennel is not a good companion

While companion planting offers numerous benefits, some combinations can hinder growth and reduce productivity. Here are plants to avoid planting near cucumbers:

  • Melons, squash, and gourds attract similar pests and require ample space to thrive.
  • Potatoes compete for soil moisture and can be affected by potato blight when planted with cucumbers.
  • Fennel inhibits the growth of nearby plants, including cucumbers.
  • Aromatic herbs like sage, basil, rosemary, and mint can affect the flavor of cucumbers or overpower other plants.
  • Brussels sprouts and other brassicas compete for nutrients and water, potentially stunting cucumber growth.
  • Drought-tolerant plants that prefer drier soil conditions should be avoided since cucumbers thrive in moist soil.

Frequently Asked Questions


Q: Can you plant cucumbers with strawberries?

A: It is not recommended to plant cucumbers with strawberries. Strawberry plants require ample space to spread via runners, which will compete with cucumbers. The shade provided by cucumbers may also hinder the growth and fruit yield of strawberries.

Q: How many cucumbers do you get per plant?

A: The yield per plant varies depending on the cucumber variety. On average, you can expect to harvest 15-20 cucumbers per plant during the growing season. Pickling varieties may yield slightly more. Creating optimal growing conditions will ensure a fruitful cucumber crop throughout the summer months.

By carefully selecting companion plants and avoiding incompatible pairings, you can create a thriving cucumber garden that yields delicious fruits. Remember to consider the unique requirements and interactions between plants to maximize their mutual benefits. Enhance the health and productivity of your cucumber plants with the power of companion planting.
