Summer Squash Companion Planting 101
Summer squash is a delightful category of squash that flourishes during the warm seasons. Among the well-known varieties, zucchini steals the show, yet there are other tasty options, such as crookneck and pattypan. Shawna Coronado, author of No-Waste Organic Gardening and 101 Organic Gardening Hacks, clarifies: "While all zucchinis are summer squashes, not all summer squashes are zucchinis. Think of zucchini as a specific player on the summer squash team."
Companion planting can be your secret weapon in fighting pests naturally. Coronado states, "Companion planting for summer squash creates a mini-ecosystem that promotes healthier, more resilient plants." By selecting plants that get along famously with summer squash, you can keep pests at bay while maximizing space and replenishing the soil with essential nutrients.
Buddy Plants For Summer Squash

Wanna reduce pests and increase pollination? Check out these 11 top-notch companion plants to create a happy, healthy squash haven:
- Beans (preferably bush beans): Sharing similar growing conditions, such as full sun and warm soil, beans are delightful companions for your summer squash. They also help fix nitrogen in the soil, which is beneficial for squash plants [1].
- Leeks: Leeks can help repel pesky carrot flies and aphids with their strong scent, creating a protective barrier around your squash plants. Plus, their vertically-growing structure won't compete with your squash for space [2].
- Lettuce: Quick-growing lettuce can be planted around young squash plants in spring, making the most of your space. Make sure to keep harvesting your lettuce regularly to clear the way for your growing squash [1].
- Peas: As a vining plant, peas typically climb a trellis vertically, avoiding competition with your sprawling summer squash. Plus, they help fix nitrogen in the soil, contributing to soil health [2].
- Radishes: Growing below ground, radishes can help break up the soil, making it easier for the squash roots to expand. Radishes can also lure pests like flea beetles away from the squash, buying your plants some time to grow strong [2].
- Spinach: Like lettuce, spinach takes up minimal space and complements summer squash. Although spinach matures quickly, it's best to plant an early-maturing, baby spinach variety to harvest in spring or early summer [1].
- Tomatoes: Both tomatoes and summer squash thrive in similar growing conditions, such as full sun and well-drained soil. The sprawling nature of squash can help suppress weeds and retain soil moisture for tomatoes [2].
- Oregano: An aromatic herb, oregano helps attract essential pollinators to boost squash pollination [2].
- Basil: Known for its delicious flavor and ability to deter mosquitoes and flies, basil also attracts beneficial insects like bees. Planting basil near summer squash can enhance the squash's flavor [2].
- Borage: Its vibrant blue flowers attract helpful pollinators like bees, while repelling unwanted pests like tomato hornworms. Plus, once autumn arrives, borage leaves can be used as mulch to enrich the soil with valuable minerals [2].
- Marigolds: By attracting pollinators and deterring pests, marigolds are a popular choice for adding color and function to your edible garden [1].
Plants To Avoid For Summer Squash Companion Planting
Not all plants play nicely with summer squash. Some will compete for the same nutrients and space or can spread diseases when planted too close. To avoid any major issues, keep these two companions at a distance:
- Potatoes: Potatoes and summer squash are not ideal companions because they have similar needs and will compete with each other for resources. Additionally, they may increase the pest risk for your squash plants [2].
- Pumpkins: Pumpkins (a type of winter squash) are not the best choice for the summer squash company. Planting winter and summer squash varieties together may lead to cross-pollination, potentially affecting fruit quality and taste. Also, pumpkins may attract similar pests and diseases, increasing your risk of an infestation [2].
By planting summer squash alongside beneficial companions like beans, corn, borage, and aromatic herbs, you can maximize growth, minimize pests, and boost overall yield, all while steering clear of incompatible plants like strawberries and cucumbers to prevent competition and plant stress [1][2][3][4]. Happy planting!

- In accordance with Shawna Coronado's advice, consider growing various types of summer squash such as zucchini, crookneck, and pattypan for a diverse harvest in your garden.
- For a happy, healthy squash garden, focus on companion plants that benefit your squash, like beans, leeks, lettuce, peas, radishes, spinach, tomatoes, oregano, basil, borage, and marigolds.
- Remember to plant the right combination of plants to maintain a thriving and pest-free garden, such as bush beans alongside summer squash to improve soil health through nitrogen fixation.
- Don't forget to avoid problematic plant pairings, including potatoes and pumpkins (winter squash), which can compete with summer squash for nutrients and resources.
- By creating a well-planned garden with companion plants that attract pollinators, repel pests, and complement each other, you'll be sure to have an abundance of fresh produce for tasty summer recipes like squash casseroles, cakes, or stews, and contribute to your overall home-and-garden and food-and-drink lifestyle.
