What is defoliation in coffee cultivation?

Defoliation is the deliberate removal of leaves from coffee trees as a farm management practice. It's used when a canopy has become too dense - particularly on closely planted farms or heavily shaded plots - to improve airflow, sunlight penetration, and cherry ripening.

With better airflow and more direct light, cherry ripening becomes more even across the canopy, and the humid microclimate that favours fungal disease - including leaf rust - is reduced. It can also redirect the tree's energy from excessive vegetative growth towards cherry development.

Timing and intensity matter. Defoliation done too aggressively or at the wrong point in the fruiting cycle can stress the tree, reduce photosynthetic capacity, and affect the following year's yield. It's a selective tool used by experienced farm managers - not something to apply routinely without a specific reason.
