Diseases and pests are a common concern for cannabis ruderalis growers. Some of the most common diseases to look out for include powdery mildew, downy mildew, root rot, fusarium wilt, and botrytis blight. These diseases can quickly spread throughout a crop if not properly managed. To reduce the risk of disease, it is important to practice good sanitation methods in your grow room or greenhouse. This includes regularly cleaning surfaces with an appropriate disinfectant solution and removing any infected plants immediately.
Pests can also be an issue when growing cannabis ruderalis outdoors or indoors. Common pests include aphids, spider mites, thrips, whiteflies, mealybugs, fungus gnats and caterpillars. It is important to keep an eye out for signs of infestation such as webbing on leaves or insects crawling around the plant. If you notice any pest activity early on it is best to take preventative measures such as using organic insecticides or installing yellow sticky traps before the problem becomes too severe.
