The Concept of Permaculture

While cannabis is mostly grown in a monoculture setting, many pot growers are slowly leaning towards a different approach– permaculture.

This concept of modern agriculture is where the art of companion gardening falls under. Check our our feminized seeds that are guaranteed to germinate.

Basically, permaculture is based on the idea of mimicking natural ecosystems in order for plants to grow as healthy and strong as possible without ever considering the need for harmful chemicals to boost plant growth.

Harmful chemicals can destroy the soil, as well as the natural ecosystem of bacteria and fungi that play a role in keeping the plants healthy.

Herbs for pest control

Herbs such as basil, cilantro, and dill, for example, can help prevent unwanted pests from eating away the nutrients and plants in your garden.

Yarrow and sunflower, on the other hand, do a good job attracting ladybirds as well as beneficial mites and insects which eat fungus gnats, scales, and spider mites.

More nourishment with companionship

Some companion plants offer added nourishment for growing cannabis. These include alfalfa, chickweed, borage and all varieties of clover.

They act as a soil amendment and fertilizer and can be used as a safer organic alternative to products that contain harmful active ingredients.

Some companion plants are rich in essential nutrients, such as nitrogen, that are needed for plant growth.

These minerals travel from the soil to the roots of the plant, allowing for healthier growth throughout the season.

Camouflaging your weed plants

The main challenge in growing your own cannabis is keeping your plants away from the sight of nosy neighbors and guests.

Sometimes, however, you have no other option but to grow these plants in your backyard.

By growing some tall, leafy companion plants, you can hide your cannabis plants and nourish them at the same time.

You can toss in some plants that offer added protection such as stinging nettles, willows, bamboos, and honeysuckle.

Hiding the smell of cannabis plants are already easily achievable with the help of aromatic herbs and flowers like jasmine, basil, lavender, and mint.

If you’re concerned that your cannabis plants will not be getting enough harvest without these products, you may want to plant oregano as a companion plant.

Similarly, stinging nettle, chamomile, and yarrow increase the production of oil in your cannabis plants, ensuring buds that are richer in resin content.

  1. So is the basil and cannabis in the same container (if your container planting) it isn’t really clear in the article and doesn’t seem to be an answer within comments…..does anyone know?

    • Hi Rhonda,

      Thanks for your message. This is mostly intended for outdoor grows, but the idea of companion plants is having them grow in the same soil. So if you’re using a pot that would mean to put them in the pot alongside your Cannabis. Make sure the pots you’re using are of adequate size, as you don’t want the plants really competing for resources. So use a pot slightly larger than you normally would for a single plant.

      We hope this helps!

      Kind regards,

  2. Unless I missed it you did not mention the benefits of growing legumes as a companion plant. Beans, peas, and clover take nitrogen from the air and deposit it in the soil. We all know the benefits of nitrogen.

  3. Can you please link to any evidence that “Growing basil as a companion plant increases oil production and resin content of the buds harvested”? Thanks in advance.

    • Sorry but this is so vague.. you’re just interested in getting people and not give them actual info.. please improve on this guys…
