GROWTH CYCLE

From flowering to harvest

Blueberries move through a natural cycle of flowering, fruit development, ripening and harvest. At our Kotagiri farm, the plants are observed through each stage of their growth cycle.

The cycle begins with bud development and flowering, followed by fruit development and ripening before the berries reach harvest.

Across five distinct phases—dormancy release, bud elongation, uniform flowering, berry enlargement, and ripening—each row receives precise nutrient ratios through computer-monitored drip lines. This careful regimentation guarantees balanced cluster densities, high sugar concentrations, and the dense natural bloom coat that defines fresh punnets.

Bud development

The buds develop and progress through the early stages of the blueberry growth cycle.

The blueberry plants progress through several early growth stages, including dormant bud, bud swell, early green tip, bud break and late green tip before reaching tight cluster.

Flowering

Pendulous bell-shaped flowers opening in clusters.

The flowering stage progresses from early bloom to full bloom, followed by petal fall and the beginning of early green fruit development.

Fruit development

Green fruit develops following flowering and continues through the fruiting stage.

Petals detach to reveal firm, pea-sized green fruitlets. Canopy management allows filtered solar radiation to reach lower branch tiers, driving rapid cellular division and accumulation of initial carbohydrates without heat stress.

Brix level 13.5°+

Ripening

Transition from green to pink to deep midnight blue with signature natural powdery bloom.

The berry matrix shifts through delicate magenta hues before deepening into midnight blue. Cool Nilgiri night breezes stimulate natural wax epicuticular excretion, creating the intact powdery white bloom that protects flavor and shelf stability.

Immediate cold-chain transfer

Harvest

Selective manual harvest between October and December.

Trained harvesting teams select only uniformly blue fruit with dry stem scars, carefully cradling clusters to preserve the natural bloom intact. Harvested berries are promptly transferred to on-site cold storage to protect freshness and texture.
