Zucchini Companion Plants

Companion planting is a great way to ensure that your zucchini plants have the best environment possible to grow. Companion planting can be a great way to increase the health and yield of your garden. Because plants can reap the benefits of each other’s traits, it is mutually beneficial to plant compatible plants close together.

Companion planting is a common strategy used by farmers and gardeners who want to preserve space, improve soil health, and prevent pests and diseases. Companion planting is a more efficient way to use your garden space while providing biodiversity, shelter, and soil health. It also acts as a living mulch that protects and feeds the soil in your garden.

Best Zucchini Companion Plants

Your garden’s productivity can be significantly improved by learning how individual plants work together. This comprehensive list of companion plants for zucchini will help you to grow the best zucchini crops possible.


This herb can double as a companion plant for zucchini plants while repelling voracious insects and attracting beneficial insects and pollinators.


Bush beans are a great way to repel garden beetles and other pests that can bore into vines and zucchini plants. As they grow, beans release nitrogen into the soil, which benefits zucchini plants and their fruit production.


Radishes are a great companion for zucchini, as they prevent squash vine beetles and borers from getting into your zucchini patch. These pests can quickly decimate your crop if not controlled.


Garlic can dissuade damaging aphids in the garden area, which cause damage to zucchini plants and their leaves.


Parsley, a fragrant herb, repels pests from the zucchini garden.


Both zucchini and spinach are mutually beneficial to each other. Zucchini offers shade and protection from the summer heat and reaps the nutritional benefits spinach gives the soil.


Like bean plants, peas release nitrogen into the soil, which helps zucchinis grow. Peas also help counter soil depletion.


Corn helps keep destructive vine borers out of your garden.


Nasturtiums are vibrant and colorful additions to any garden that attract beneficial pollinators. Aphids (a highly destructive pest) love nasturtium plants. Clever companion planting can purposely use the nasturtium plants to attract aphids and then sacrifice them to protect other plants from these pests.


You can also drive out tiny aphids, which eat zucchini and other vegetables.


Poor Zucchini Companion Plants

Some plants are great friends, while others are not. There are very few companion plants that zucchini won’t love, but they do exist.


Squash and pumpkin are members of the same family, which can cause cross-pollination, leading to poorly formed fruits.


Interplanting potatoes with zucchini plants is overall a bad idea. Both plants are susceptible to the same pests, which makes them more vulnerable to infestation. Potatoes are also heavy feeders and can take a lot of nutrients out of the soil.

Overall Garden Care

Companion planting has many benefits, but is not meant to replace proper garden preparation and maintenance. A successful garden will thrive with regular watering, periodic feeding, essential light requirements, and nutrient-rich soil. Healthy soil is essential for healthy roots. To give your companion garden the best start, amend your soil before you plant your plants. Your knowledge of companion planting can be applied to any gardening method, including container and in-ground gardening.
