Keep reading to learn how to grow a healthier garden.

Key Takeaways

  • Planting parsley with tomatoes, peppers, asparagus, beans, and marigolds makes your garden healthier by controlling pests naturally and boosting plant growth.
  • Avoid planting parsley near fennel, alliums (like onions and garlic), and lettuce to prevent competition for nutrients or attracting harmful pests.
  • Parsley helps the soil by attracting good bugs like hoverflies and parasitic wasps which eat common garden pests. This means you don’t have to use chemical pesticides.

Benefits of Companion Planting with Parsley

Companion planting parsley brings benefits to your garden. It naturally controls pests, boosts the growth and health of other plants, and enriches the soil with nutrients. These benefits support a healthier garden ecosystem.

Natural Pest Management

Parsley attracts hoverflies, which eat aphids, thrips, and other pests. This helps with pest control in the garden. Marigolds and nasturtiums also keep away unwanted insects while bringing in pollinators that help plants grow strong.

By having these plants together, your garden has fewer pests naturally.

Growing parsley with these companion plants increases beneficial insects like parasitic wasps. These wasps prey on common garden pests such as caterpillars and codling moths. The result is a healthier garden without using chemical pesticides.

This method protects both your plants and the environment.

Enhanced Plant Growth and Health

Moving from keeping pests away, companion planting with parsley also makes plants grow better and healthier. Planting parsley next to certain veggies like tomatoes and asparagus can boost their growth.

This happens because parsley helps improve the soil health around them. For example, beans add nitrogen to the soil, which is like a power food for plants nearby. This means all these friends in the garden get stronger and taste better too.

Growing parsley alongside flowers such as marigolds not only adds beauty but also improves the overall well-being of your garden space. Marigolds deter bad bugs, while attracting good ones that pollinate plants, leading to more fruits and vegetables.

So, placing parsley near these companions ensures your garden is both pretty and productive without using chemical fertilizers or pesticides.

Top Companion Plants for Parsley – Parsley Companion Plant

Parsley has great companions in the garden. It grows well alongside tomatoes, peppers, asparagus, beans, and marigolds. These plants work together to create a healthier garden environment.


Tomatoes help keep away aphids and hornworms, making them great partners for parsley in the garden. Both plants need 6-8 hours of sunlight each day to grow well. Together, they also bring in helpful bugs that protect the garden.

Growing tomatoes with parsley boosts plant health and wards off pests, thanks to their mutual sun needs and ability to attract beneficial insects.


Peppers are excellent companion plants because they enhance soil health. They thrive in full sun but can tolerate some light shade, just like parsley. This makes them a great match for growing alongside each other in your garden.

Next, let’s talk about Asparagus as a companion plant for Parsley to maximize your garden’s potential!


Asparagus is a great companion plant for parsley because it helps repel asparagus beetles. Both parsley and asparagus do well in soil that drains easily, so they can thrive together in the garden.

These two plants work well together to create a healthy and thriving garden environment.

Both asparagus beetles are kept at bay by planting parsley with asparagus, preventing any harm to your crops.

Beans and Peas

Peas and Beans are excellent companion plants for parsley. Beans help the soil stay healthy by adding nitrogen, which is good for parsley’s growth. Peas thrive in USDA Hardiness Zones 2-11, needing moist, well-drained soil and full sun to partial shade to grow well.


Marigolds grow best in USDA Hardiness Zones 7-9 and thrive in loamy, sandy, well-drained soil. They act as effective pest deterrents and trap crops, making them great companion plants for parsley.

These vibrant flowers not only enhance the garden’s beauty but also contribute to its overall health and resilience.

Moving on to the next topic about “Plants to Avoid Near Parsley”.

Plants to Avoid Near Parsley – Parsley Companion Plant

Avoid planting fennel, mint, and lettuce close to your parsley. These plants can hinder each other’s growth due to competition for nutrients or may attract pests harmful to one another.


Fennel competes with parsley for nutrients, hindering its growth. This plant releases chemicals that can inhibit the growth of neighboring herbs like parsley. When grown next to fennel, parsley may not thrive as it would when planted alongside compatible companions.

Therefore, it’s advisable to avoid planting fennel in close proximity to your parsley if you want them both to flourish.

Alliums (Onions, Garlic, etc.)

Alliums like onions and garlic can negatively affect the growth and flavor of parsley. They both need well-drained soil but might compete for space. Planting them together may cause issues because they belong to the same family as parsley.

It’s best to keep these plants at a distance from each other in your garden.


Lettuce may attract pests that can harm parsley. Also, both lettuce and parsley need similar soil conditions, leading to competition for nutrients and space in the garden.
