Growth Stages

Dormancy & Chilling

November-February, depending on zone

Tree is leafless; requires 700-800 chilling hours (below 45°F) for proper flower bud development

Do not prune or fertilize during dormancy. Ensure cold requirement is met for fruiting. Thin newly planted trees to single stem if multi-branched.

Bloom & Flowering

3-4 weeks, typically March-April

White blossoms appear on spurs before leaves emerge; flowers are delicate and vulnerable to late frost

Monitor for frost damage during bloom. Provide protection if late freezes are forecast. Do not apply nitrogen fertilizer during this period. Ensure pollinator activity by maintaining bee-friendly environment.

Fruit Set & Young Fruit Development

4-6 weeks after bloom

Small green fruits develop after petal drop; natural fruit drop occurs as tree self-regulates load

Thin fruits to 1 every 2-3 inches when they reach marble size to ensure larger, higher-quality fruit. Remove diseased or damaged fruits immediately. Maintain consistent watering.

Fruit Growth & Ripening

8-10 weeks, typically June-August depending on zone

Fruits enlarge and gradually change from green to yellow-green with light spots; sugar content increases

Continue consistent watering; do not let soil dry out. Support heavy branches with props if needed. Apply balanced fertilizer in mid-summer if growth is slow. Watch for pest activity, especially Japanese beetles.

Harvest & Post-Harvest

August-September, depending on zone

Fruits reach full size and develop characteristic flavor; skin may develop slight pink or russet blush on sun-exposed side

Pick fruits when slightly soft to touch; they continue to develop flavor for 1-2 days after picking. Do not harvest too early or flavor will be lacking. Prune lightly after harvest to shape tree and remove diseased wood.

Harvest Tips

Pick fruits in late August to early September when they are slightly soft and yield gently to pressure; a mature fruit will have a fragrant aroma.

Fun Facts

🌱 Reine Claude Verte is named after Queen Claude of France (1494-1524), wife of Francis I, and is considered one of the finest greengage plums ever developed.
🌱 Despite being called a 'green' plum, at full ripeness it turns golden-yellow with a slight translucent quality, revealing the pale green flesh within.
🌱 This variety is self-fertile but produces heavier crops with cross-pollination from other European plum varieties such as Mirabelle or Italian prune plums.
