Course Overview
Leaf curling or distortion is a symptom, not a complete diagnosis by itself.
This course teaches students to read the shape, age, distribution, and timing of distorted leaves before choosing a response.
Students compare common categories such as pests, water stress, environmental stress, recent fertilizer or spray use, handling injury, virus-like symptoms, and normal foliage variation.
The main skill is restraint: inspect first, choose one supported correction, and then observe whether new growth improves.
Course Outcomes
- Describe different distortion patterns such as curling, cupping, twisting, and puckering.
- Compare new-growth distortion with older-leaf damage.
- Separate pest evidence from cultural, environmental, spray, and timing clues.
- Inspect undersides, nodes, tender tips, and recent care changes before acting.
- Use a checklist to choose one evidence-based next step.
