Course introduction

Healthy crops don’t happen by accident

They are the result of a dynamic balance between the plant, its environment, and the pressures that surround it. The Plant Health Circle brings these elements together in one clear model.

A pest or disease only becomes a real problem when three factors align:

  • The pest or disease is present
  • The conditions allow it to thrive
  • The plant is susceptible

Modern horticulture invests heavily in the first two: exclusion, hygiene, climate control, monitoring technologies. But the third factor (the plant’s own resilience) often holds the key to long-term success.

While the Basic Principles describe the foundations of Plant Empowerment, the knowledge in this program goes a step further. It focuses specifically on plant health. An area that is not covered in depth in the book, but has become increasingly crucial in modern greenhouse production.

Want to learn more before you decide?

Understand how plant resilience, climate, root health and biology work together. Through live webinars, practical assignments and expert sessions, you’ll learn how to apply the Plant Health Circle in daily greenhouse practice.
