Visual lesson 05
Leaf inspection workflow
Inspect upper and lower surfaces, new and old growth, margins, veins, petioles, pests, residue, and progression over time.
Interactive academic visual
Leaf inspection workflow
Inspect position, surfaces, structures and progression in a consistent orderCanopy position
Start by recording whether the leaf is new or old growth and upper, middle or lower canopy.
