How to Grow Grape Chardonnay Pommard Clone

Vines are leafless during winter. In spring, buds swell and break into new growth with emerging shoots and leaves.

Prune during dormancy to remove dead wood and establish desired canopy structure. Thin shoots at bud break to 1 shoot per spur for quality fruit.

Shoots elongate rapidly, producing leaves and lateral shoots. Flowering occurs 6-8 weeks after bud break with small, inconspicuous flower clusters (inflorescences).

Manage canopy by removing excess shoots and leaves to ensure adequate light penetration. Establish training system (cordon, cane, or trellis). Fertilize moderately—excess nitrogen promotes vegetative growth at the expense of fruit quality.

Flowers are pollinated and berries develop from successful flowers. Berries grow rapidly and change color from green to yellow-green, then to mature golden hues.

Monitor for powdery mildew and downy mildew; apply sulfur or approved fungicides as needed. Thin clusters if yields are excessive to improve fruit quality. Reduce leaf area gradually to expose ripening berries to sunlight.

Berries begin véraison (ripening phase), changing from green to golden yellow. Sugars accumulate, acids decrease, and phenolic compounds develop, creating complex flavors.

Continue disease management. Adjust irrigation to maintain consistent soil moisture without waterlogging. Harvest when desired sugar level (typically 23-24° Brix for Chardonnay) and acidity balance are achieved.

Berries reach target ripeness with concentrated sugars. After harvest, vines begin leaf senescence and prepare for dormancy.

Harvest in early morning for optimal flavor compounds. Handle berries carefully to minimize oxidation and skin damage. Allow vines to fully acclimate to dormancy before winter.
