If you’re growing cannabis at home, whether indoors or outdoors, you’ve likely considered ways to keep your plants healthy, avoid pests, and increase yields—all while avoiding harmful chemicals. One of the best methods to do this is by using companion plants. These are plants that grow harmoniously alongside your cannabis, offering benefits like natural pest control, improved soil health, and even enhanced growth. In this post, we’ll cover the best companion plants for cannabis, how to use them, and why they’re essential for any organic cannabis garden.

Let’s dig into how you can use nature’s best buddies to make your cannabis garden thrive!

Why Use Companion Plants with Cannabis?

Companion planting has been around for centuries, used by gardeners who want to maximize the natural interactions between plants. When it comes to growing cannabis, the benefits of companion planting go beyond just keeping your garden green. Companion plants can help:

• Repel pests naturally: Say goodbye to chemical pesticides. Some plants release strong scents that deter common cannabis pests like aphids, spider mites, and whiteflies.
• Attract beneficial insects: You’ll bring in helpful insects like ladybugs, predatory wasps, and hoverflies that snack on pests.
• Improve soil quality: Certain plants fix nitrogen or enhance the soil structure, helping your cannabis plants grow stronger without needing synthetic fertilizers.
• Enhance flavor and yield: Some companion plants can even help boost your cannabis plants’ growth and potentially improve their flavor and potency.

This method is perfect for organic cannabis growers or anyone looking to create a sustainable garden that’s healthier for plants and the environment.

Best Companion Plants for Cannabis

Here are some of the best companion plants for cannabis that will not only support the health of your garden but can also improve your cannabis growing experience.

Marigolds: The Ultimate Pest Fighter

When it comes to natural pest control, marigolds are a powerhouse. These vibrant flowers repel many pests that love to feed on cannabis, including aphids, whiteflies, and nematodes. Their strong smell confuses pests and keeps them away from your precious buds.

• How to Use: Plant marigolds around the perimeter of your garden or in pots near your cannabis plants. They’re easy to grow and will flower throughout the growing season, making them a bright, beautiful, and functional addition.
• Bonus Benefit: Marigolds attract pollinators like bees, which can improve the overall biodiversity of your garden.

Basil: A Flavorful Pest Repellent

Not only is basil great for your pesto, but it’s also a fantastic companion plant for cannabis. Basil’s strong scent repels mosquitoes, aphids, and spider mites—three common pests that can wreak havoc on your cannabis crop. Some growers even swear that basil improves the flavor and aroma of cannabis by boosting its terpene production.

• How to Use: Plant basil alongside your cannabis plants or in containers placed nearby. The fragrant oils in basil will help keep pests at bay, while its leaves make for a tasty kitchen herb.
• Bonus Benefit: Basil (potentially) enhances the taste and aroma of your cannabis plants by increasing terpene production.

Clover: The Nitrogen Fixer

Clover is a little-known secret in companion planting for cannabis. It’s is a nitrogen-fixing plant, meaning it pulls nitrogen from the air and stores it in the soil. Nitrogen is a crucial nutrient for cannabis, promoting healthy, vigorous growth. Clover also acts as a natural living mulch, helping to retain soil moisture and suppress weeds.

• How to Use: Plant clover between your cannabis plants or around their base. Clover grows low to the ground, so it won’t compete with your cannabis for sunlight, and it helps improve the soil for future plantings.
• Bonus Benefit: Clover adds organic material to the soil as it grows, improving soil structure and promoting root health for your cannabis plants.

Lavender: Aroma and Pest Control

If you want to add a soothing scent to your garden while also keeping pests away, lavender is your go-to companion plant. Lavender’s strong fragrance repels pests like fleas, moths, and whiteflies. It can also help mask the scent of cannabis, which is a bonus for discreet outdoor growers.

• How to Use: Plant lavender near the edges of your cannabis garden or in containers around your plants. Its flowers will not only brighten up the garden but will also keep pests at bay.
• Bonus Benefit: The scent of lavender can enhance your cannabis plants’ terpene profile, giving your buds a subtle hint of floral aroma.

Yarrow: The Insect Magnet

Yarrow is an excellent companion plant if you’re looking to attract beneficial insects to your garden. Yarrow’s flowers bring in pollinators like bees and butterflies while also attracting predatory insects like ladybugs and parasitic wasps that feast on pests like aphids and caterpillars.

• How to Use: Plant yarrow around your cannabis plants or in areas of the garden where pest pressure is high. Yarrow can grow in both garden beds and containers, making it a versatile addition.
• Bonus Benefit: Yarrow’s deep roots help aerate the soil and improve nutrient absorption, which can benefit your cannabis plants.

Dill: Pest Control and Pollination Helper

Dill is a dual-purpose companion plant for cannabis—it repels pests like spider mites while attracting beneficial insects that help control pest populations. Hoverflies, ladybugs, and parasitic wasps all love dill, and they’ll help keep your cannabis garden free of pests without chemicals.

• How to Use: Plant dill throughout your cannabis garden, particularly near problem areas where pests tend to congregate. It grows tall, so keep it positioned where it won’t block sunlight from your cannabis.
• Bonus Benefit: Dill is a delicious herb to have on hand for your culinary needs, and its feathery foliage adds a unique texture to your garden.

How to Plan Your Cannabis Companion Garden

Now that you know the best companion plants for cannabis, here’s how to incorporate them into your garden.

1. Identify Your Garden’s Needs: Determine what your cannabis garden needs most—whether it’s pest control, improved soil health, or added biodiversity. This will help you decide which companion plants are best for your situation.
2. Space Your Plants Wisely: Companion plants, like dill and yarrow, can grow tall and might overshadow your cannabis if planted too closely. Be sure to give your cannabis plants enough space to thrive while using companion plants to fill the gaps.
3. Use Companion Plants in Rotation: Every plant has a different growing cycle. Rotating your companion plants seasonally helps keep the soil healthy and ensures that pests don’t become resistant to any particular plant’s benefits.

Conclusion: Let Nature Work Its Magic

Companion planting for cannabis is a natural and effective way to enhance your garden’s health without using chemicals. By planting marigolds, basil, clover, lavender, yarrow, and dill alongside your cannabis, you can repel pests, improve soil quality, attract beneficial insects, and even improve the taste and smell of your buds.

Whether you’re growing cannabis indoors or outdoors, companion planting will help create a thriving, eco-friendly garden that rewards you with better yields and healthier plants. Try it out this growing season, and watch your cannabis garden flourish!
