What To Plant With Cilantro? The Ultimate Companion Planting Guide
Cilantro thrives when strategically paired with other plants that offer mutual benefits, making companion planting essential for a robust and pest-free harvest. Some of the best companions include carrots, onions, dill, basil, and mint, offering pest deterrence, improved growth, and enhanced flavor.
Understanding Cilantro and Companion Planting
Cilantro, also known as coriander (the seeds), is a fast-growing annual herb beloved for its distinctive flavor. Companion planting involves strategically placing different plants together to enhance their growth, deter pests, attract pollinators, or improve soil conditions. The benefits extend beyond simple aesthetics; it’s a form of natural pest control and a method to maximize garden space and yield. Successful companion planting hinges on understanding the needs and interactions of each plant. Cilantro can be tricky to grow, bolting quickly in hot weather, making careful planning even more vital.
The Benefits of Companion Planting with Cilantro
Choosing the right companions for cilantro can significantly impact its health and productivity. Some key benefits include:
- Pest Control: Certain companion plants, like marigolds, repel common cilantro pests.
- Improved Growth: Some plants, such as chamomile, are believed to stimulate cilantro growth.
- Shade Provision: Taller plants can provide crucial shade, preventing premature bolting in hot climates.
- Enhanced Flavor: Growing certain herbs nearby can subtly influence cilantro’s flavor profile.
- Attracting Beneficial Insects: Many companion plants attract pollinators and predatory insects that keep pests in check.
Top Companion Plants for Cilantro and Why They Work
Here are some of the most effective companion plants for cilantro, along with the reasons behind their success:
- Carrots: Cilantro repels carrot root flies, while carrots loosen the soil, benefiting cilantro’s roots.
- Onions and Garlic: These pungent plants deter aphids, which can plague cilantro.
- Dill: Dill attracts beneficial insects like lacewings and ladybugs, which prey on aphids and other cilantro pests. Dill also makes a good trap crop, drawing pests away from cilantro.
- Basil: Basil repels flies and mosquitoes and is believed to enhance cilantro’s flavor.
- Mint: Mint can deter aphids and other pests, though it’s crucial to keep it contained as it spreads aggressively.
- Marigolds: These cheerful flowers are known for their pest-repelling properties, especially against nematodes.
- Chamomile: Chamomile is believed to stimulate growth and improve the overall health of cilantro.
- Lettuce: Provides ground cover and some shade for cilantro roots.
Plants to Avoid Planting Near Cilantro
While companion planting can be incredibly beneficial, some plants can negatively impact cilantro’s growth or attract unwanted pests. These should be avoided:
- Fennel: Fennel inhibits the growth of many plants, including cilantro.
- Parsley: Both parsley and cilantro are susceptible to similar diseases, increasing the risk of infection.
- Rue: Rue has been reported to inhibit cilantro growth.

Frequently Asked Questions (FAQs)
Why does cilantro bolt so easily?
Cilantro is prone to bolting, or going to seed prematurely, due to heat stress and long daylight hours. Planting it in the spring or fall, providing afternoon shade, and regularly harvesting the leaves can help delay bolting. Consider planting bolt-resistant varieties as well.
Can I plant cilantro with tomatoes?
Yes, you can plant cilantro with tomatoes, especially in areas prone to tomato hornworms. Cilantro attracts beneficial insects that prey on hornworms. However, be mindful of the different watering needs: tomatoes prefer consistently moist soil, while cilantro benefits from slightly drier conditions.
Does cilantro attract pollinators?
Yes, cilantro attracts several pollinators, including bees and hoverflies, which are beneficial for overall garden health and the pollination of other plants.
How far apart should I plant cilantro from its companions?
Spacing depends on the specific companion plants. Generally, maintain the recommended spacing for each plant individually. As a guideline, allow at least 6-8 inches between cilantro and its companions.
What are the best soil conditions for cilantro?
Cilantro prefers well-drained soil with a pH of 6.5 to 7.0. Amend the soil with organic matter to improve drainage and fertility.
How often should I water cilantro?
Water cilantro regularly, especially during dry periods. Aim to keep the soil consistently moist, but avoid overwatering, which can lead to root rot.
Can I grow cilantro indoors with companion plants?
Yes, you can grow cilantro indoors with companion plants like basil or chamomile. Ensure they receive adequate sunlight (or use grow lights) and are planted in appropriately sized containers.
What’s the best time of year to plant cilantro?
The best time to plant cilantro is in the spring or fall, avoiding the hottest months of summer. This helps prevent premature bolting.
How do I harvest cilantro to encourage more growth?
Harvest cilantro regularly by snipping off the outer leaves, leaving the inner leaves to continue growing. This encourages bushier growth and delays bolting.
Is cilantro considered a nitrogen fixer?
No, cilantro is not a nitrogen fixer. Legumes, such as beans and peas, are known for their nitrogen-fixing abilities.
How does companion planting affect the flavor of cilantro?
Some gardeners believe that companion planting can subtly influence cilantro’s flavor. Planting it near basil or chamomile, for instance, may enhance its aroma and taste.
What are the signs that my cilantro needs a companion plant?
Signs include stunted growth, yellowing leaves, frequent pest infestations (such as aphids), and rapid bolting. These may indicate that your cilantro is struggling and could benefit from the protection and support of a companion plant.
