How to Use Pest Repelling Plants to Protect Your Cannabis Crop

If you are a cannabis grower, you know how frustrating it can be to deal with pests that can damage or destroy your plants. Whether you grow indoors or outdoors, you need to take preventive measures to keep your crop healthy and pest-free. One of the most natural and effective ways to do that is to use pest-repelling plants as companions for your cannabis plants.

Repelling plants are plants that emit strong odors or substances that deter or naturally repel parasites and bugs. Some of these plants also attract beneficial insects that prey on the pests, creating a natural balance in your garden. By planting these repellent plants around or near your cannabis plants, you can create a protective barrier that will reduce or eliminate the need for chemical pesticides.

Some of the most common pests that attack cannabis plants are spider mites, aphids, fungus gnats, caterpillars, whiteflies, thrips, and grasshoppers. These pests can cause various problems for your plants, such as sucking their sap, chewing their leaves, spreading diseases, and reducing their yield and quality. To prevent these pests from infesting your garden, you can use some of the following plants:
