Establishment (Year 1-2)
2 yearsYoung tree develops root system and branch structure; minimal or no flowering in first year
Remove any early flowers to encourage growth. Water regularly and stake for support if necessary. Prune to develop strong scaffold branches. Apply mulch 3-4 inches deep around base.
Flowering (Spring, Year 2-3+)
2-3 weeksTree produces abundant white to pale pink flowers in clusters along branches before leaves emerge
Ensure adequate chilling hours (800-900 hours below 45°F) for proper flowering. Thin flowers if overly abundant to prevent stress. Provide pollinator access; Reine Claude requires cross-pollination from compatible varieties like Stanley, Greengage, or Damson plums.
Fruit Development (Late Spring-Early Summer)
6-8 weeksSmall green fruit forms after petal drop; fruits swell and develop characteristic round shape
Thin fruits to 2-3 inches apart (one fruit per cluster) when marble-sized for larger fruits. Apply balanced fertilizer if growth is slow. Maintain consistent watering to prevent fruit cracking.
Ripening (Mid to Late Summer)
4-6 weeksFruits transition from green to greenish-gold with slight blush; flesh becomes sweet and juicy; sugar content increases
Reduce nitrogen fertilizer to concentrate sugars. Water consistently but not excessively to prevent cracking. Watch for pest and disease pressure; monitor for brown rot and plum curculio.
Harvest & Dormancy (Late Summer-Fall)
Harvest 2-4 weeks; dormancy 4-6 monthsMature fruits reach full sweetness and color; tree prepares for winter dormancy
Harvest fruits when fully ripe (they should yield slightly to gentle pressure). Prune in late winter to remove diseased wood and maintain open canopy structure. Apply dormant oil spray in late winter if pest pressure was high.

Common Pests
-
Install pheromone traps; prune to improve air circulation; apply spinosad or neem oil during early fruit development; remove fallen fruit promptly
-
Thin fruit for air circulation; remove mummified fruit; apply sulfur or copper fungicide in spring; prune for open canopy structure
-
Hand-pick early morning; use Japanese beetle traps; apply neem oil if infestation is severe; maintain tree vigor
-
Prune infected branches 12 inches below the knot; burn or dispose of infected wood; apply dormant oil and sulfur in spring
-
Strong water spray to dislodge; apply horticultural oil or insecticidal soap; encourage beneficial insects like ladybugs
Uses
Fresh Eating & Desserts
CulinaryReine Claude plums are exceptional for eating fresh due to their exceptional sweetness, honey-like flavor, and firm-but-tender flesh. They are prized for making jams, preserves, compotes, and elegant desserts such as plum tarts and poached plums. [source]
Pruneaux & Dried Fruit
CulinaryReine Claude fruits are traditionally dried to make premium prunes (pruneaux in French), which are sweeter and less tart than many commercial prune varieties. Dried Reine Claude prunes are considered a delicacy in European cuisine. [source]
Digestive Health
MedicinalPlums, particularly Reine Claude, are rich in sorbitol and dietary fiber, which promote healthy digestion and gut motility. Both fresh and dried fruits have been traditionally used to support digestive function and natural laxative properties. [source]
Antioxidant & Nutritional Value
HouseholdReine Claude plums contain high levels of antioxidants including phenolic compounds, vitamin C, and vitamin K, supporting overall health and immune function. The fruits are low in calories and rich in essential minerals. [source]
Pollinator & Wildlife Support
WildlifeThe abundant spring blossoms attract bees and other pollinators essential for fruit set. Ripe fruits provide valuable late-summer food for birds and wildlife, supporting ecosystem health in home orchards. [source]

Harvest Tips
Harvest fully ripe fruits in late summer (typically July-August in Northern Hemisphere) when they reach full greenish-gold color and yield slightly to gentle pressure. Fruits do not ripen significantly after picking, so wait for peak ripeness on the tree. Pick early morning when fruits are coolest. Handle gently to avoid bruising. Reine Claude keeps well in cool storage (32-40°F) for 2-4 weeks.
Fun Facts
- 🌱 Reine Claude translates to 'Queen Claude' in French and is named after Queen Claude of France (16th century), wife of King Francis I, to whom the plum was gifted for her exceptional flavor and quality.
- 🌱 This heirloom cultivar is one of the oldest cultivated plum varieties still widely grown and is considered the ancestral type for the 'Greengage' plum classification, though Reine Claude is technically distinct with its own superior flavor profile.
- 🌱 Reine Claude requires cross-pollination from compatible plum varieties to produce fruit abundantly, making it essential to plant at least two different plum varieties for successful home orchard production.
