This section helps you identify the most common plant diseases growers encounter—powdery mildew, blight, botrytis, rust, damping off, leaf spot, and more—understand what conditions allow them to take hold, and respond in a way that supports long-term plant and soil health. Everything here is based on hands-on experience and years of observation in real growing environments, not theory alone.

We view disease as a signal of imbalance rather than a failure—often tied to airflow, moisture, nutrient cycling, or microbial disruption. These pressures are part of natural systems, and when corrected properly, they lead to stronger, more resilient plants over time. Each disease is addressed through a three-tier Integrated Disease Management (IDM) approach: direct treatments to reduce active infection, internal support to strengthen plant immunity and soil biology, and environmental or biological strategies that help restore balance and prevent recurrence. This resource exists because we care about the people using it—and we want to help you move forward with clarity, confidence, and healthier plants.
