The art of using companion plants is becoming very popular in the cannabis era. The practice involves using other plants so that they defend your precious ganja. Many of them are everyday herbs and flowers that you may already be familiar with. Some of them attract beneficial insects – such as those that provide pollination. Others keep predators at bay. Again, others can help support the growth of your cannabis by enriching the soil or other beneficial aspects on the environment. Finally, there are even plants that can increase the yield of your crops.

If you plant them strategically, these plants can either do their job on their own, or together to enhance your cannabis plants. We have categorized them in 4 different types and we’ll elaborate these below.

1. Defending Plants

These companion plants are suitable for defending your growing weed seedlings in a variety of ways. They are able to keep looters away. Even better: They also attract insects that defend your cannabis.

  • Chamomile: Chamomile is used as a herb or to make tea, but it also keeps white flies and wireworms at bay. When you plant it next to your cannabis plant, it’s the best way to put up a “No Entry” sign for destructive insects. Atomizing chamomile tea on weed seedlings also keeps them from contracting fungal infections. This is a big problem for young plants. Spreading cuttings here and there around your struggling plants also helps to give them a boost.
  • Dille: This delicate herb is related to carrot and fennel. That’s why gardeners keep these plants away from dill because cross-pollination can easily occur. It is also a popular herb in the kitchen. In the garden, however, dill is also a powerful protective companion plant. It attracts honeybees, hoverflies and beneficial wasps. Caterpillars also like to nibble on dill instead of on surrounding plants. The plant also repels other invaders, including beetles, mites and aphids. Dill is easy to grow and can be sown directly around your cannabis plants without any problems.
  • Lavender: Lavandula angustifolia is one of those herbs that everyone knows. It is used in perfumes, soaps and other cosmetics. It is also an insect magnet for beneficial cannabis insects and keeps pests at bay. Insects that feed on nectar love this plant. However, mice, fleas, ticks and moths are repelled by the scent of this plant. Plant them in all corners of the garden that need to be protected.
  • Sunny Flowers: As with some of the other companion plants, you cannot go wrong with sunflowers. They are beautiful. They attract the right insects for cannabis growers and drive away the bad ones. They can also shield your plants from prying eyes if you’re growing covertly. They are also great for the soil. Their roots are so effective that they are even used to filter gray water in organic systems. They are even used in processing radioactive water in Fukushima.
  • Thursday: This cute little plant is one way to add tufts of color to your garden. Achillea millefolium is especially welcome for another thing. If you plant it around your little garden, centipede can increase the production of essential oils in nearby plants. However, they should be kept on the sides so that there is no competition from the roots among them. The insects that centipede attracts are excellent plant protectors. Including ladybugs, hoverflies, lacewings and mini wasps. All of these insects help keep your crop safe from other predatory insects and other pests.

2. Scary Plants

This assortment of companion plants literally causes panic among the “bad guys.” Most of these plants either have a strong smell or secrete oils that literally act as an insect repellent. Plant them around your cannabis plants for a colorful and also protective garden.

  • Basilicum: This lush summer-loving plant will create a beautiful foliage in your garden. This so-called “Prince of Plants” will also protect and nourish your cannabis garden. There are tomato growers who even claim that it improves the taste of their tomatoes. For the same reason, it could also increase the production of terpenes if you grow it in the company of cannabis. Terpenes are the essential oils found in cannabis. Any way you can increase that amount is a good asset to your cannabis garden. Because of this herb being so easy to grow and often used in cooking you are always on the right track with this plant. It likes a sunny spot but can be grown indoors or outdoors. While it attracts a whole host of beneficial insects, basil also repels invaders. Including aphids, crioceris, mosquitoes and white flies.
  • Kervel: This shade-loving annual plant produces white and pale magenta-colored flowers. It also provides lush growth to neighboring plants, including cannabis. Chervil is a fantastic protective plant – snails stay at a safe distance.
  • Coriander: This plant is also known to have seeds that have narcotic properties. It was also once used as an aphrodisiac. Today, growers are finding that the pungent scent of cilantro keeps aphids, spider mites and Colorado potato beetles at bay. Hoverflies and an array of parasitic wasps are also attracted to this plant. They also provide anti-aircraft defense against looters. There is another fantastic way to apply cilantro as a deterrent to pests. Grind the seeds and make tea of them. Once the liquid cools it is an excellent spray for your plants.
  • Lavender: Once again starring in one of our other packs. The scent of this lovely purple plant is the greatest weapon against intruders. Not only does this plant repel fleas, ticks and moths; it also keeps mice from nibbling on your cannabis. Ironically, lavender is used to attract people. It has long been incorporated into soaps and all kinds of other perfumes. Because of all these benefits, lavender has been planted in gardens for over three thousand years.
  • Gold flows: These beautiful yellow-orange plants were often used for garden borders. Known to both attract and repel insects, they can also improve plant growth. If you add marigolds to your compost pile you can automatically improve the soil for your cannabis. Marigolds also produce a chemical in the roots which is also a powerful insect repellent that can be effective for years.

3. Nutritional Plants

The plants in this group are fantastic for improving the soil and the location of your cannabis. Some even support the plant with a root system that increases water drainage. Others literally act as natural, living mineral suppliers, starting with oxygen.

  • Alfalfa: Alfalfa is an amazing companion plant. Why? She can help with local water drainage. She is deep-rooted, which reduces evaporation. This means you don’t have to water you weed seedlings as often. It also means that they are able to drag neighboring plants through dry periods. As for the soil, there’s more good news, too. The plant regulates nitrogen; it helps keep the nitrogen level in the soil at a healthy level. It also provides iron, magnesium, phosphorus and potassium. These are all essential minerals for growing cannabis. The benefits of alfalfa as a companion plant are therefore quite rewarding. The plant also promotes the growth of dandelions which helps break down the soil and allows water to penetrate the soil better. Tea is also made from the plant itself which is then misted over cannabis to improve growth.
  • Cucumber herb: This beautiful plant produces lavender-colored flowers throughout the growing season. The leaves and flowers are edible – they have a pleasantly tangy flavor. Cucumber is also a hardy plant that does well under the same conditions as cannabis. Growing it as a companion plant can improve the health of your plants. That’s because it pumps vitamins and minerals into the soil. The minerals the plant itself contains are ideal for dry mulch. Cucumber compost can help your cannabis slowly absorb potassium and calcium for vital growth and energetic photosynthesis.
  • Horn flower: Known by its scientific name Cerastium biebersteinii, this is a type of soil clover with a short life span. It is bursting with white flowers in late spring and early summer. It’s also great for your compost pile. It is literally living mulch that also provides protection for the soil. This keeps moisture in the soil next to your plants instead of evaporating.
  • Red claver: Trifolium pratense is one of the best companion plants on the planet. Why? It “regulates” nitrogen in the root area. This allows neighboring plants to take up nitrogen. The complex root structure also allows for natural water drainage. This allows water to penetrate the soil better. Since little can go wrong with this plant, cannabis enthusiasts in training will love it too.
  • White claver: Also known as Trifolium repens. Basically living mulch that you can use as a carpet for the spaces between other plants. Because of the structure of its roots, white clover also regulates nitrogen in the atmosphere. As the plant breaks down, nitrogen is released to the soil. Cannabis plants are fond of this element. White clover is a workhorse and hard to break down. It can also substantially reduce the need for other types of fertilizer.

4. Stealthy Plants

These strategic plants each have their own advantages. They tend to be large and concealing or they nicely disguise the smell of your cannabis. Most of the time they are also beautiful, smell good or look good, sometimes they taste great too. For that reason alone you should get at least one of the plants in this group.

  • Lavender: Mentioned again because of its distinctive scent. Lavender has been used for centuries to please the nose. It keeps moths away, ticks, aphids and mites. Mice don’t like it much either. The oil from the leaves can be used to make a spray to repel mosquitoes.
  • Lemon balm: These plants are a welcome addition to any natural pharmacy. They can be used for many things besides being a good companion plant as a cover because of its concealing scent. It also attracts insects that provide pollination and chases pests out of the garden with its strong scent. For dessert, it also causes neighboring plants to have a certain citrus accent. Use that to animate your entire “herb” garden.
  • Golden flows: These plants are great boosters for neighboring plants. The roots are great to throw on your compost pile. They also repel insects. These plants produce brilliant bright orange flowers. They also keep aphids, mosquitoes, beetles, dwarf cicadas and roundworms at bay. Rabbits also prefer carrots.
  • Mint: Mint is a popular herb anyway. However, it is also a strong companion plant to cannabis. Its deliciously strong scent chases away mosquitoes, cockroaches, ants and other types of insects that sting, and helps cover up the smell of your cannabis. However, the plant does sometimes grow a little too happily on its own. Unless you maintain it carefully, it will become quite rampant.
  • Sunflowers: Sunflowers not only look beautiful, they are also very functional. They have been cultivated for over 4,000 years for their foliage, oil and protective nature. They are hardy plants that can even be used to drain water. However, when it comes to companion plants, sunflowers also do their part. They lure destructive invaders including aphids away from other plants. The power of the sunflower itself protects them from insect attacks. As an aid to stealth, sunflowers grow large and bright and thus distract attention from the green hues of cannabis.
