Companion planting is the close planting of various plants that improve growth and protect from preying pests. Just as carrots love tomatoes, cannabis is partial to several different companion plants that will organically get rid of pests in the garden. Consider planting any of the following companion plants right in the same pots as your weed and pests will be sure to steer clear.

  • Basil: Not only is basil extremely easy to grow, but its distinct aroma will deter aphids, beetles, and flies.
  • Garlic: Garlic is a fungicide by nature and help protect your garden from getting infested with disease. It helps safeguard your plants from both pests and mold.
  • Mint: This sweet-smelling plant is a huge turn off to garden pests. They straight up abhor the smell. If using mint as a companion plant, it’s best to keep it in separate pots that are placed near your plants as it tends to spread like crazy.
  • Chili Peppers: If you’ve got pesky rabbits, mice, and deer that are trying to invade your garden, planting chili peppers with your plants will keep them far away. The root system of chili peppers also releases a chemical that can help prevent rot, which can be a lifesaver in areas with heavy rainfall.
  • Marigolds: These bright flowers have been used in gardens for years to keep away deer and rabbits. They can also help control worms and other leaf-munching insects.

Neem Oil

Pressed from the seeds and fruit of the neem tree, this oil is excellent for killing or repelling all kinds of insects and mites. Aphids, whiteflies, snails, mealy bugs, worms, flies, and more hate the bitter taste of neem and will stay far away from plants treated with it. It is also excellent at controlling fungus and mold.

To effectively use neem oil to get rid of garden pests, mix 3 capfuls of neem oil with a drop or two of liquid soap (to break up the oil), with one quart of lukewarm water. Spray this mixture on your plants and it will kill off the larvae and eggs of infesting pests.


Ants are another common garden pest that can quickly infest your cannabis plants. One of the most effective and inexpensive ways to get rid of ants that have begun to colonize in your cannabis. All you need to do is take about a tablespoon of powdered cinnamon and sprinkle it on the soil where the ants are. You can also dissolve cinnamon in water and sprinkle this over the soil. Ants can’t stand the flavor of this common spice and will soon send ants on the merry way.

These are all tried and true ways to organically get rid of garden pests that try to invade your crop. They aren’t just for using on cannabis plants either. Use these natural pesticides on any of your garden plants to ensure your harvest is exactly as nature intended. Abundant, healthy, and full of the fruits of your labor.
