Pruning timing
winter
Rejuvenation and framework building Only on frost-free days; strongly stimulates growth.
summer
Growth suppression and aeration After harvest or in July; reduces the risk of Monilia.
Remove
- Upright water sprouts
- Inward-growing branches
- Dead or diseased wood
- Crossing or rubbing branches
Preserve
- Short fruiting wood (fruiting spurs)
- Horizontal side shoots
- Healthy main leaders
Avoid
- Pruning during frost below -5°C
- Excessive pruning (promotes water sprouts)
- Pruning during rain (risk of infection)
Tools and hygiene
Disinfect tools with 70% alcohol after each tree to prevent the spread of bacterial canker.

FAQ
How can I tell when greengages are ripe?
The fruits yield to light pressure, smell sweet, and the color usually changes from dark green to a lighter greenish-yellow or yellow.

Introduction
The greengage, also known as Reine Claude, is widely considered the finest of all plums. With its honey-sweet, spicy aroma and succulent flesh, it is the ultimate dessert fruit for the home garden.
History
Named after Queen Claude of France (Reine Claude), this subspecies of plum spread throughout Europe starting in the 16th century. It has long been a symbol of peak culinary quality.

- gummosis
- stress
- bacterial_canker
First checks
- Check site for waterlogging
- Inspect bark for mechanical damage
Prevention strategy
Cultural
- Whitewashing trunks in winter
- Balanced fertilization
Monitoring

- Weekly aphid checks
Organic first response
- Prune out infested shoots immediately
- Apply grease bands
Notes
Hygiene is crucial for stone fruit; disinfect tools after pruning infected trees.
Diagnosis
Common misdiagnoses
Plum pox virus is often mistaken for harmless nutrient deficiency.
Phenology
Stages
- Bud swelling
- Flowering period (April/May)
- Fruit set
- Fruit development and coloring
- Fruit ripeness (August/September)
- Leaf fall and winter dormancy
Notes
Flowering occurs shortly before or simultaneously with leafing out; greengages often bloom very profusely.
