Introduction to Companion Planting for Cannabis
Companion planting is an organic and sustainable method of cultivating cannabis by growing other plants alongside it. This practice provides numerous benefits, such as pest control, soil improvement, and increased biodiversity. In this article, we will delve into the world of companion planting for cannabis, discussing its benefits, the best companion plants to use, and how to implement this technique in your own garden.
The Benefits of Companion Planting for Cannabis
There are several advantages to using companion planting for cannabis cultivation:
- Natural Pest Control: Many companion plants can deter pests that are harmful to cannabis, either by emitting odors that repel insects or by attracting beneficial predators that feed on these pests.
- Soil Improvement: Certain companion plants can fix nitrogen in the soil, making it more nutrient-rich and promoting healthier cannabis growth.
- Increased Biodiversity: Introducing various companion plants increases the biodiversity in your garden, which can lead to a more balanced ecosystem and a healthier environment for your cannabis plants.
- Camouflage and Odor Control: Some companion plants can help mask the strong smell of cannabis, making your grow less detectable to nosy neighbors or potential thieves.
Top Companion Plants for Cannabis Cultivation
To optimize your cannabis companion planting, consider incorporating the following plants into your garden:
- Marigolds: These vibrant flowers are known for their ability to repel pests like aphids, whiteflies, and nematodes. They also release a substance called alpha-terthienyl, which is toxic to certain soil-dwelling pests and can help protect your cannabis plants.
- Basil: Basil is a popular culinary herb that can also repel insects like thrips, aphids, and spider mites. Its strong aroma can also help mask the smell of cannabis.
- Nasturtiums: Nasturtiums are beautiful, edible flowers that can attract beneficial insects like ladybugs and lacewings, which prey on pests such as aphids and whiteflies. They can also serve as a trap crop for pests like aphids, which prefer nasturtiums over cannabis.
- Yarrow: This medicinal herb can attract beneficial insects like ladybugs, hoverflies, and lacewings. Yarrow is also known for its ability to accumulate nutrients in the soil, providing a nutrient boost for your cannabis plants.
- Clover: Clover is a nitrogen-fixing plant that can help improve soil fertility. It can also attract beneficial insects like predatory wasps and ladybugs, which help control pests.
Implementing Companion Planting in Your Cannabis Garden
To successfully incorporate companion planting into your cannabis garden, follow these steps:
- Plan Your Garden Layout: Before planting, plan your garden layout to ensure that your cannabis plants and companion plants will coexist harmoniously. Consider factors such as sunlight requirements, growth patterns, and spacing needs.
- Choose the Right Companion Plants: Select companion plants that will provide the specific benefits you are seeking for your cannabis garden, such as pest control, soil improvement, or odor control.
- Plant Companion Plants Strategically: Place companion plants in strategic locations throughout your garden to maximize their benefits. For example, plant marigolds around the perimeter to create a natural pest barrier or plant basil close to cannabis plants to help mask their odor.
- Monitor and Maintain Your Garden: Keep a close eye on your cannabis and companion plants, and address any issues that arise promptly. Regularly prune, water, and fertilize as needed to ensure the health and success of your garden.
Additional Companion Plants to Consider

The Impact of Companion Planting on Cannabis Yield
While companion planting can offer several advantages to your cannabis garden, it’s essential to understand that the direct impact on cannabis yield can vary. Factors such as the specific companion plants chosen, the overall health of your cannabis plants, and the effectiveness of your garden management practices will all influence the success of your companion planting efforts. That said, implementing companion planting can create a healthier environment for your cannabis plants, which may indirectly lead to improved yield and overall plant vitality.
What should I not plant around cannabis?
When cultivating cannabis, it’s important to be aware of plants that may have a negative impact on your cannabis garden. These plants can compete for resources, attract pests, or create other unfavorable growing conditions. Below is a list of plants you should avoid planting near your cannabis:
- Walnut Trees: Walnut trees release a substance called juglone, which can be toxic to cannabis plants. Juglone can stunt growth and potentially kill cannabis plants, so it’s best to keep them away from walnut trees.
- Fennel: Fennel is known to inhibit the growth of other plants, including cannabis. Its allelopathic properties can negatively impact the growth and development of your cannabis plants.
- Sunflowers: While sunflowers can attract beneficial insects and pollinators, they are also known to be allelopathic, which means they can release chemicals that inhibit the growth of other plants, including cannabis.
- Mustard: Mustard plants can attract pests like aphids and whiteflies, which can then spread to your cannabis plants. To minimize the risk of attracting these pests, avoid planting mustard near your cannabis garden.
- Cotton: Cotton is susceptible to various pests and diseases that can also affect cannabis plants. To minimize the risk of cross-contamination, it’s best not to plant cotton near your cannabis garden.
- Sorghum: Similar to sunflowers, sorghum can release allelopathic chemicals that can inhibit the growth of other plants, including cannabis. To avoid any potential negative effects on your cannabis plants, keep sorghum away from your garden.
- Cucumbers: Cucumbers can attract pests like spider mites, which can infest and damage your cannabis plants. To minimize the risk of attracting these pests, it’s best to avoid planting cucumbers near your cannabis garden.
When planning your cannabis garden, it’s crucial to research the plants you intend to grow alongside your cannabis plants. This will help you avoid any potential issues related to competition, allelopathy, or pest attraction. By carefully selecting the right companion plants, you can create a harmonious and thriving cannabis garden.
