Grow a Healthier Garden with Parsley Companion Plants

Parsley companion plants are your garden’s secret weapon! These strategic allies do more than share space with your parsley – they can boost growth, improve flavor, and even keep troublesome pests at bay. 

Think of them as your parsley’s plant posse, a green team assembled to help your herbs thrive. Let’s dive in and discover the best companion plants for parsley and how to transform your garden into a cooperative ecosystem.

What Is Companion Planting?

Companion planting is a time-tested gardening practice where different plants are intentionally grown close together for mutually beneficial reasons. It’s like creating a mini-ecosystem in your garden bed, where each plant plays a specific role to support its companions’ success.

Think of it like a team effort. While your parsley focuses on producing those delicious, leafy greens, its companion plants might be busy in attracting helpful pollinators or disguising the scent of your parsley.

You can create a more resilient and productive garden ecosystem by strategically placing these “plant friends” around your parsley. It’s a win-win situation for both your parsley and its companions!

Benefits of Parsley Companion Plants

While companion planting offers numerous advantages to a garden in general, let’s delve specifically into the benefits it brings to your parsley patch:

Enhanced Growth and Flavor: Certain companion plants, like marigolds and nasturtiums, release compounds that can improve the nutrient uptake of nearby plants. This can lead to sturdier parsley plants with more vibrant foliage and a richer flavor.

Natural Pest Control: like many herbs, Parsley can be susceptible to pests like aphids and caterpillars. Companion planting with aromatic spices like basil, oregano, and thyme can help deter these unwanted visitors. The strong scents released by these herbs can mask the attractive odors of your parsley, making it less conspicuous to pests.

Improved Pollination: although not entirely dependent on pollinators for fruiting, Parsley still benefits from their presence. Planting flowers like dill and fennel near your parsley can attract bees, butterflies, and other pollinators. These beneficial insects will not only help your parsley produce seeds but also contribute to the pollination of different flowering plants in your garden.

Increased Efficiency and Space Optimization: Companion planting allows you to maximize space in your garden. You can utilize vertical space more effectively by strategically placing shorter plants like parsley between taller companions like tomatoes or peppers.

Reduced Weed Growth: The increased plant diversity and denser planting with companion planting can help suppress weed growth. This is because weeds struggle to compete for sunlight, water, and nutrients in a closely planted bed. This translates to less time spent weeding and more time enjoying your flourishing parsley plants.

10 Companion Plants to Grow With Parsley

Now that you understand the benefits of companion planting let’s explore some specific plant partners that thrive alongside your parsley:

  • Tomatoes
  • Chives
  • Carrots
  • Corn
  • Peppers
  • Onions
  • Peas
  • Asparagus
  • Basil
  • Nasturtiums 

1. Tomatoes

This dynamic duo benefits from each other in several ways. Parsley attracts hoverflies, which prey on aphids, a common pest of tomatoes.

In return, tomatoes provide shade for the parsley during the hottest parts of the day, preventing it from drying out.

2. Chives

These delicate and flavorful herbs are perfect companions for parsley. They have similar water and sunlight needs, making it easy for them to grow together.

Chives also repel aphids, further protecting your parsley from these pesky insects.

3. Carrots

While they belong to the same family (Apiaceae), carrots and parsley can still be good companions with certain considerations. Parsley flowers attract tachinid flies, which feed on carrot pests like cutworms.

4 Plants to Keep Away From Parsley

Regarding companion planting, it’s about who thrives alongside your parsley and who might hinder its growth or attract unwanted pests. Here are four plants to keep at a distance from your parsley:

1. Mint

While mint is a beloved herb, its aggressive spreading habit can quickly overwhelm and outcompete your parsley. Its fast-growing roots can deplete the soil of water and nutrients, leaving your parsley struggling to thrive. It’s best to dedicate a separate space for mint or grow it in a container to prevent it from taking over your entire garden bed.

2. Carrots

While they belong to the same family, carrots and parsley can compete for the same resources and attract similar pests like carrot root flies. However, they can still be occasional companions with proper management. Planting them together for one season before rotating crops helps disrupt pest life cycles.

3. Lettuce

While both parsley and lettuce enjoy similar soil moisture, parsley’s presence can stress lettuce plants and cause them to bolt (go to seed prematurely) faster. This is because parsley releases volatile compounds that can affect the growth cycle of lettuce. To avoid this, plant your lettuce at a safe distance or in a separate bed from your parsley.

4. Onions

While onions can benefit some plants, their strong scent can inhibit the growth of certain herbs, like parsley. Additionally, onions can be competitive plants, hindering parsley’s access to essential resources. If you plant them together, ensure adequate spacing and monitor your parsley for signs of stunted growth.

This list is not exhaustive, and your specific soil conditions and gardening practices might influence these recommendations. Observing your plants and understanding their needs can create a thriving and harmonious garden ecosystem for your parsley and its companions.


1. What should not be planted next to parsley?

Avoid planting mint, carrots (especially for extended periods), lettuce, and onions directly next to your parsley. Mint’s aggressive roots can crowd out parsley, while carrots and parsley attract similar pests. Lettuce can bolt (flower prematurely) due to parsley’s presence, and onions’ strong scent can inhibit parsley’s growth.

2. What grows best with parsley?

Parsley thrives alongside tomatoes, chives, peppers, asparagus, corn, peas, and certain flowers like nasturtiums and marigolds. These plants offer various benefits, such as providing shade, attracting beneficial insects, deterring pests, and improving soil quality.

3. Can I plant parsley and coriander together?

Yes, parsley and coriander (cilantro) can be planted together as they have similar needs for sunlight, water, and soil. However, be mindful of spacing to avoid competition for resources.

4. Can you grow basil and parsley together?

Basil and parsley can be excellent companions as they share similar growing conditions, and both deter pests with their strong scent. However, ensure they receive adequate sunlight and drainage to thrive together.

Final Thought

Companion planting with parsley offers a fun, sustainable, and rewarding way to enhance your garden. 

By understanding the unique needs of your plants and choosing the right companions, you can create a biodiversity-rich ecosystem that promotes healthy growth, natural pest control, and, ultimately, a more productive and enjoyable gardening experience. 

So, get creative, experiment with different combinations, and watch your parsley and the entire garden flourish!
