The best plants to grow near zucchini and squash are companions that repel pests, attract pollinators, and don’t compete for the same nutrients.
 
If you’ve been wondering what to plant near zucchini and squash, you’re in the right place.
 
Companion planting is one of those old-school gardening tricks that actually works, and when done right, it can make a huge difference in your harvest.
 
Zucchini and squash are heavy feeders and magnet for pests like squash bugs and vine borers, so the right neighbors can help protect them naturally.
 
In this post, we’ll explore what to plant near zucchini and squash, why these companion plants work, and which ones you should keep far away.
 
Let’s dig in.
 

What to Plant Near Zucchini and Squash

Choosing what to plant near zucchini and squash comes down to three goals: pest control, pollination, and healthy soil.
 
Here are the best companion plants for zucchini and squash:
 

1. Nasturtiums

Nasturtiums are one of the best plants to grow near zucchini and squash.
 
They act as a trap crop for aphids and squash bugs, luring pests away from your squash plants.
 
Plus, their bright flowers attract pollinators that help zucchini and squash produce more fruit.
 

2. Marigolds

Marigolds are a classic companion for zucchini and squash.
 
Their strong scent repels nematodes in the soil and confuses pests looking for a meal.
 
Planting marigolds near zucchini and squash also adds a pop of color to your garden beds.
 

3. Radishes

Radishes make great neighbors for zucchini and squash because they grow quickly and mature fast.
 
They help break up compacted soil, making it easier for squash roots to spread.
 
Radishes also repel cucumber beetles, which can damage zucchini and squash vines.
 

4. Beans and Peas

Beans and peas are legumes, which means they pull nitrogen from the air and fix it into the soil.
 
Since zucchini and squash are heavy feeders, planting beans or peas nearby gives them a natural nutrient boost.
 
Just make sure the beans or peas get enough sun and don’t crowd your squash vines.
 

5. Borage

Borage is a lesser-known but powerful companion for zucchini and squash.
 
It attracts bees and other pollinators, which means more flowers get pollinated and more squash develops.
 
Borage also deters pests and can improve the flavor of nearby crops, according to some gardeners.
 

6. Corn

Corn works well near zucchini and squash in traditional Three Sisters planting.
 
The corn provides a tall stalk for beans to climb, while squash vines spread along the ground and shade out weeds.
 
Just be careful not to let squash vines climb the corn and pull it down.
 

Why These Companion Plants Work for Zucchini and Squash

Companion planting near zucchini and squash isn’t just folklore—there’s real science behind it.
 

1. Natural Pest Repellent

Many companion plants release compounds that repel squash bugs, aphids, and cucumber beetles.
 
This reduces the need for chemical pesticides and keeps your zucchini and squash healthier.
 

2. Pollinator Attraction

Zucchini and squash rely on bees and other pollinators to set fruit.
 
Flowering companions like borage and nasturtiums draw those pollinators right to your squash patch.
 

3. Soil Improvement

Legumes like beans and peas add nitrogen to the soil, which feeds hungry zucchini and squash plants.
 
Radishes and other taprooted companions break up compacted soil so squash roots can reach deeper.
 

4. Weed Suppression

Low-growing companions can shade the soil and slow weed growth around zucchini and squash.
 
Less weeding means more time enjoying your garden and less time pulling unwanted plants.
 

What NOT to Plant Near Zucchini and Squash

Just as some plants help zucchini and squash thrive, others can cause problems.
 
Avoid planting these near your squash:
 

1. Potatoes

Potatoes compete with zucchini and squash for nutrients and water.
 
They can also attract similar pests, making infestations worse.
 

2. Fennel

Fennel releases compounds that can stunt the growth of nearby plants, including zucchini and squash.
 
It’s best to keep fennel in its own corner of the garden.
 

3. Other Squash Varieties

Planting zucchini near other squash varieties can lead to cross-pollination.
 
This won’t hurt the fruit you harvest this year, but it can affect the seeds you save for next season.
 

So, What to Plant Near Zucchini and Squash?

The best plants to grow near zucchini and squash are nasturtiums, marigolds, radishes, beans, peas, borage, and corn.
 
These companions repel pests, attract pollinators, and improve the soil so your zucchini and squash can thrive.
 
Avoid planting potatoes, fennel, or other squash varieties nearby, as they can compete for resources or cause cross-pollination.
 
With the right companions, your zucchini and squash will be healthier, more productive, and easier to manage all season long.
 
Happy planting.
