First flush

nounStandard termFarming

The initial wave of new growth, buds, or harvestable yield produced by a plant in a single season.

This marks the earliest and often most vigorous emergence of leaves, flowers, or fruiting bodies after a period of dormancy. In specialty crops like tea or mushrooms, this initial harvest is highly prized for its distinct flavor profile and commands a premium price. Growers track this timing closely to coordinate labor for picking and to schedule subsequent pruning or nutrient applications.
