How to Grow Greengage Plum 'Reine Claude Violette'

Young tree developing framework with vegetative growth dominating. Minimal or no fruit production expected.

Remove flower buds first year to direct energy to root and branch development. Prune to establish strong central leader or open vase form. Water regularly; apply growth-stage fertilizer (higher nitrogen).

White to pale pink blossoms appear on 1-2 year old wood in early to mid-spring. Self-fertile but cross-pollination improves set; other plum varieties aid pollination.

Protect from late frost with row covers if necessary. Do not fertilize heavily during bloom; avoid pruning during flowering. Monitor for pest activity.

Fruit begins developing rapidly after pollination. Tiny green plums enlarge; thinning is critical for quality fruit. Young fruit gradually develops characteristic violet-red blush over greenish-gold base.

Thin fruit to 3-4 inches apart (one fruit every 4-6 inches of branch) when marble-sized. Remove diseased or misshapen fruit. Reduce nitrogen fertilizer; switch to potassium/phosphorus formulation. Maintain consistent watering.

Fruit reaches full size (1.5-2 inches diameter), develops deep violet coloring with slight whitish bloom. Flesh becomes translucent greenish-gold and increasingly sweet.

Reduce watering gradually to concentrate sugars and enhance flavor, but ensure adequate moisture to prevent cracking. Monitor for splitting during heavy rain; harvest slightly early if downpours forecast. Thin any remaining overcrowded fruit.

Fruit reaches peak ripeness with soft flesh and maximum sugar content. Tree begins preparing for dormancy after harvest.

Harvest when fruit is fully soft and comes away with gentle twist. Eat fresh or process immediately. Prune lightly after harvest if needed. Resume normal watering if conditions dry. Apply winter dormancy preparations.
