What Are the Best Companion Plants for Zucchini?


Growing zucchinis is easy, but pairing them with the right companion plants can boost your harvest, as what makes zucchinis even more remarkable is their ability to thrive when surrounded by compatible plant companions.

By strategically selecting and pairing plants that complement and support your zucchinis, you can deter pests, enhance pollination, and improve overall plant health; companion planting offers a holistic approach to gardening beyond the pursuit of growing a single crop.

Follow the tips in this article to maximize your harvest and enjoy popular zucchini dishes like zucchini bread, muffins, and noodles.

What Is Zucchini?

Zucchinis, scientifically known as Cucurbita pepo, is a popular and versatile summer squash that belongs to the Cucurbitaceae family.

These green-skinned vegetables are widely loved for their mild flavor, tender texture, and culinary versatility.

They typically have an elongated cylindrical shape with smooth, dark green skin.

However, yellow and striped varieties are also available and range in size from small to medium but can grow quite large if left on the plant for an extended period.

Zucchinis offer several health benefits, as they are low in calories, high in water content, and a good source of fiber, minerals, and vitamins.

So, consuming zucchinis can support digestion, hydration, and overall well-being.

They are also a good source of vitamins A and C, potassium, and dietary fiber and contain antioxidants.

Types of Zucchini

Some popular zucchini varieties include the classic dark green zucchini, yellow zucchini (also known as golden zucchini), and striped zucchini, such as the Cocozelle variety.

Why Is Companion Planting Important for Zucchini?

Companion planting is like playing matchmaker for your plants.

It’s all about finding suitable plant buddies to support and benefit each other in the garden. So, why is companion planting important for zucchinis?

Here are a few reasons.

Reason #1: Weed Control

Companion plants with dense foliage, such as legumes or certain groundcovers like clover, can act as living mulch, suppressing weed growth around zucchinis.

This helps reduce competition for nutrients and water, allowing your zucchinis to thrive.

Reason #2: Sun Protection

Tall plants like corn or sunflowers can create shade, preventing zucchinis from scorching during hot summer days.

On the other hand, zucchinis’ broad leaves can provide shade to more delicate companion plants, shielding them from excessive sun exposure.

Reason #3: Nutrient Sharing

Certain companion plants have deep root systems that can reach nutrients deep within the soil.

When grown alongside zucchini, these plants can help bring essential nutrients to the surface, making them more accessible to the zucchini plants and promoting overall plant health.

Reason #4: Enhanced Pollination

Some companion plants, like bee-friendly flowers or herbs like borage, attract pollinators like bees and butterflies.

These beneficial insects are crucial in pollinating zucchini flowers, resulting in better fruit sets and higher yields.

Reason #5: Pest Management

Companion planting can help repel pests that commonly affect zucchinis.

Plants such as marigolds, nasturtiums, and radishes act as natural pest deterrents, keeping harmful insects at bay and reducing the risk of infestations.

Companion Plants for Zucchini

Here are the best companion plants for zucchini.

Companion Plant #1: Marigolds


Marigolds are known for their strong scent and help ward off harmful insects and nematodes that can harm zucchinis.

Their natural pest control properties make them an excellent companion plant, keeping your zucchinis healthier and pest-free.

Companion Plant #2: Radishes


When grown alongside zucchinis, radishes serve as a deterrent against squash vine borers and cucumber beetles.

These pests are repelled by the presence of radishes, providing protection to your zucchinis and preventing potential damage.

Companion Plant #3: Borage


Borages are herbs that boast beautiful blue flowers that attract pollinators such as bees.

Planting borage near your zucchinis ensures better pollination for the zucchini flowers, leading to improved fruits and higher yields.

Companion Plant #4: Corn

Tall corn plants can shade zucchinis, shielding them from excessive sun exposure during scorching summer days.

By doing this, corn helps prevent zucchinis from wilting or getting sunburned, promoting their health and productivity.

Companion Plant #5: Nasturtiums


These colorful flowers act as a natural pest repellent, deterring aphids and squash bugs that can damage zucchinis.

Planting nasturtiums nearby creates a protective barrier for your zucchinis, reducing the risk of infestations.

Companion Plant #6: Sunflowers


Besides adding a touch of beauty to your garden, sunflowers can offer shade and protection to zucchinis.

Their towering height and broad leaves create a natural canopy, shielding zucchinis from intense sunlight and reducing moisture loss.

Companion Plant #7: Lettuce


Planting lettuce near zucchinis offers dual benefits.

Firstly, lettuce provides some shade to zucchinis, preventing direct exposure to sunlight and reducing the risk of sunburn.

Secondly, the lettuce’s shallow roots help retain soil moisture, benefiting both plants by conserving water resources.

Companion Plant #8: Dill


The feathery foliage of dill attracts beneficial insects such as wasps and ladybugs.

These insects are natural predators of zucchini pests like aphids and caterpillars, providing organic pest control and safeguarding the health of your zucchini.

Companion Plant #9: Oregano

Oregano not only adds flavor to your foods but is also a beneficial companion to zucchini.

Its aromatic properties help repel pests, while its dense foliage acts as a ground cover, minimizing weed growth and competition for resources around zucchinis.

Companion Plant #10: Beans

Legumes, such as beans, have the incredible ability to fix nitrogen in the soil.

Planting beans near zucchinis enriches the soil with nitrogen, an essential nutrient for plant growth.

This helps to improve the vigor of your zucchinis.


Your zucchinis will grow more abundantly with the right companion plants.

Apply the techniques discussed in this article during your next planting season and enjoy the benefits of increased zucchini yields.

Not only will you have more to eat, but you’ll also have plenty extra to share with friends, family, and neighbors.
