When cultivating cannabis, it’s important to be aware of plants that may have a negative impact on your cannabis garden. These plants can compete for resources, attract pests, or create other unfavorable growing conditions. Below is a list of plants you should avoid planting near your cannabis:

  5. Cotton: Cotton is susceptible to various pests and diseases that can also affect cannabis plants. To minimize the risk of cross-contamination, it’s best not to plant cotton near your cannabis garden.
