Basil: A Classic Food Ingredient And Cannabis Companion Plant

Basil is a great companion plant for your cannabis garden. It repels parasites and is a handy fresh ingredient for many tasty recipes. Terpenes and other compounds that comprise basil’s pleasant aroma also display therapeutic properties.

Some plants act as natural parasite repellents. Basil is a garden favourite worldwide because its strong scent is good for us and our recipes, but pests such as aphids and flies hate it. Companion planting is based on the idea that plants can form cooperative partnerships that deter pests and encourage better garden health, even without pesticides. Basil is a great companion plant for your cannabis garden too.


There are many varieties of basil hybrids. The most commonly cultivated is sweet basil, or Genovese basil, but we also have Thai basil, lemon basil, holy basil, and many others. It is one of the most used herbs in cuisines worldwide, and it’s very easy to grow. The same compounds that make basil’s aroma so pleasant also show therapeutic potential in essential oil form.


Different species of basil produce different essential oils containing terpenes and other biochemical compounds. The qualitative and quantitative composition of these essential oils can be quite diverse, however, common basil contains high concentrations of estragole and linalool, together with cineole, eugenol, and myrcene. This combination of aromatic compounds is the reason why basil leaves can make even the simplest of recipes so tasty. The same combination acts as a bug repellent, similarly to citronella or lemongrass, and research has found basil essential oil to have antioxidant, antibacterial, and antifungal properties.

Fresh basil leaves are a great way to add flavour to recipes, and some dishes rely on basil as their primary ingredient, such as pesto alla genovese. Basil leaves are most commonly used fresh and added at the last moment as cooking degrades its aromatic compounds. Basil essential oil is less suitable for cooking, for it’s much more concentrated and potent as an active principle than raw leaves, stems, and flowers.

The potential health benefits of basil essential oil range from the ability to treat nausea, motion sickness, indigestion, constipation, and respiratory problems, up to fighting inflammation and bacterial/viral infections. It can be used aromatically, topically, or internally, and you can also use basil oil to sanitise kitchens and bathrooms, prevent contamination, purify the air, and enhance your mood. You can even add basil oil to your mouthwash or toothpaste, which can also be homemade.


Members of a companion cannabis garden should be planted close together, but not so close as to cause competition for root space, air, light, and nutrients. Basil is a great companion plant for a wide variety of veggies, including pepper and chili pepper, eggplant, potato, tomato, asparagus, cabbage, beets, beans, as well as herbs like peppermint.

It’s a short-lived, mostly annual plant that grows best in moist, well-draining soil in a sunny location. It doesn’t require more than 8 hours of sunlight a day, and it benefits from some shade in the afternoon. Daytime temperatures must be above 21°C (70°F) and nighttime temperatures must be above 10°C (50°F) to avoid damage. When transplanted, basil seedlings should be spaced 30cm (12in) apart, with 45cm (18in) between rows.

The apical growth of the plant can be pinched to encourage the growth of new shoots, similarly to what happens with cannabis. Harvesting leaves regularly keeps the plants productive, and the fresh leaves can be kept for a short time in the refrigerator, or for a longer period in the freezer.

There is no way basil can steal nutrients and light from a grown-up cannabis plant, and it is said that this herb has the power to improve the flavour of veggies, cannabis included, when they grow together as companion plants. True or not, with all these advantages and few hassles, there’s no reason not to plant some basil around your ganja garden.

Cannabis Companion Planting: Basil

As well as being the main ingredient of delicious pesto, basil may be worth introducing to your outdoor garden in hopes of protecting your valuable cannabis crop and assisting them in reaching their maximum yield potential. Welcome to the world of companion planting.


What Is Companion Planting?

Just about any form of gardening requires innovation to ensure yields can be grown faster, more efficiently and provide better quality. However, the innovation present in the cannabis industry is probably the most rapidly evolving within the whole field. Growers are constantly and successfully finding new ways to boost the health of their plants and with it the output of fresh, dank buds, that act as recreational delights.

A number of techniques, pieces of equipment and methods now exist for growers to choose from to achieve these goals, though not all of them involve high-tech machinery, lights and fans, that require hefty overhead costs. In fact, some of these methods come directly from Mother Nature herself, such as the humble yet potent basil plant.

Companion planting is based on the idea that some plants can form synergistic and cooperative partnerships when planted within a certain proximity. Some plants have the ability to act as natural pesticides and repellents, that help protect your crop within its growing environment. Other plants may be used for the opposite; perhaps they are so attractive to pests, that they simply cannot resist them. In this case a plant can act as a decoy or shield, while the actual crop of interest remains healthy and defended.

There is very little strict, scientific research confirming the legitimacy of companion planting. However, this has been a trial and error process over an extended period of time and a result of direct action within the field. Common occurrences that have proven to be effective are at the root of companion planting.

Companion Planting With Basil

When it comes to basil, it seems this crop offers a number of benefits when used as a companion. There are many different types of basil, from Thai varieties to holy basil. However, the basil found commonly among Italian dishes is sweet basil. This sweetly scented herb is easy to grow and a fast find. It requires around 6 to 8 hours of sunlight a day to grow optimally with a preference for moist, yet well-drained soil.

Basil has been observed to be an effective companion for a wide variety of plants, including chillies, bell peppers, aubergine, marigold, oregano, potatoes, tomatoes, cabbage, beets, beans and asparagus. This long list of vegetation is a testament to the team spirit of the basil plant. Basil has been seen to attract beneficial life forms such as butterflies into the garden environment, whilst repelling harmful and damaging insects. Such unwanted guests include mosquitoes, tomato hornworms, whiteflies, aphids and asparagus beetles.

Another important analysis of growing basil among other crops is its apparent ability to improve the flavour of a plant and several online forum posts boast about its ability to increase oil production in cannabis plants – though this has yet to be confirmed and proven. Using basil as a companion plant for your cannabis could lead to some very interesting growing outcomes.

Companion planting uses synergy between plants to improve the health and yield of cannabis plants. Find out how weed and basil might work together in such a way
