Introduction

When I first started growing cannabis outdoors, I faced a common challenge: pest infestations. Aphids, leafhoppers, and other nuisances seemed to wreak havoc on my plants. However, a simple and effective solution came in the form of companion planting. By integrating specific plants alongside my cannabis, I not only managed to reduce pest problems but also attracted beneficial predators to my garden, creating a balanced ecosystem. This last summer I had the pleasure of meeting spiders, praying mantis, dragonflies, ladybugs, lizards, and even some frogs and toads in my garden. In this blog post, I'll discuss the benefits of companion planting for outdoor cannabis growth and introduce you to some easy-to-grow companion plants, such as basil, marigolds, nasturtium, sage, thyme, and mint. I grow many of these plants in pots and my strategy is to surround my cannabis plants with potted companion plants. These plants acted as a natural barrier preventing pests from attacking my cannabis plants.

1. Basil:

Benefits:

- Pest Repellent: Basil emits a strong aroma that naturally deters common cannabis pests like aphids, flies, and mosquitoes.

- Enhances Flavor: The fragrant basil leaves can be used in cooking and provide a tasty addition to your meals.

- Attracts Beneficial Insects: Basil's white flowers attract pollinators, such as bees.

2. Marigolds:

Benefits:

- Natural Pest Control: Marigolds release chemical compounds that repel nematodes and other soil-borne pests, reducing the risk of root damage.

- Colorful Blooms: Marigolds' vibrant flowers not only add a pop of color to your garden but also attract pollinators and beneficial insects.

- Companion for Other Plants: Marigolds can be planted as a border around your cannabis plants to create a protective barrier.

3. Nasturtium:

Benefits:

- Aphid Deterrent: Nasturtiums are a favorite among aphids, serving as a "trap" plant. Aphids are attracted to nasturtium leaves, drawing them away from your cannabis.

- Edible Flowers: Nasturtium flowers and leaves are edible and make a zesty addition to salads.

- Ground Cover: Nasturtiums can also act as a ground cover, reducing weed growth and soil erosion.

4. Sage:

Benefits:

- Repels Insects: Sage's aromatic leaves naturally repel a variety of insects, including cabbage moths, carrot flies, and more.This year my sage actually attracted all the grasshoppers and katydids. It was torn up pretty badly over the summer BUT it saved my cannabis plants from getting eaten alive by grasshoppers and katydids. 

- Culinary Use: Sage is a versatile herb for cooking and can be used to flavor various dishes.

5. Thyme:

Thyme 

Benefits:

- Insect Repellent: Thyme repels insects like cabbage worms, whiteflies, and spider mites.

- Culinary Herb: Thyme is a popular culinary herb, adding flavor to many dishes, including roasted meats and soups.

- Low-Maintenance: Thyme is easy to grow and requires minimal care, making it a hassle-free companion plant.

6. Mint:

Mint 

Benefits:

- Pest Deterrent: Mint's strong aroma repels common garden pests, including ants and rodents.

- Culinary Uses: Mint is widely used in cooking, particularly for making teas, desserts, and cocktails.

- Ground Cover: Mint spreads quickly and can act as a ground cover, suppressing weeds and retaining moisture in the soil.

*Pro Tip!!! Mint can be quite invasive if grown in the ground. It just grows and grows and grows! I highly recommend growing any kind of mint in a container. 

Fun Fact!!! We have 6 chickens and we have a trench in front of their chicken run that is full of mint! It helps deter mice from entering the chicken coop and our chickens eat the mint during the summer and it helps keep them cool in the hot weather! We love mint.
