Plant Profile
Sour cherryPrunus cerasus
The sour cherry (Prunus cerasus) is a popular fruit tree species known for its tart fruits. It is more robust and easier to care for than the sweet cherry and is well-suited for home gardens. Harvest takes place in summer, and the fruits are versatile, used in everything from pies to liqueurs.

Not suitable for indoor cultivation.
Direct sowing is not common. Grafting is the usual propagation method.
Planting & site
Sour cherry: Planting and spacing
The best planting times are spring (March-April) and autumn (October-November).
Site & practical notes
Sour cherries are relatively undemanding and tolerate pruning well. Ensure good crown ventilation to prevent fungal diseases. Harvest is usually in summer, and the fruits are very tart, making them ideal for processing.

Overview
Most sour cherry cultivars are self-fertile, but require cross-pollination from another sour cherry cultivar or a suitable sweet cherry cultivar for good fruit set and high yields.
Notes
Although self-fertile, pollination by a compatible cultivar significantly improves yield and fruit quality. Pay attention to cultivars with similar flowering times.
Pruning & care

Pruning type
Renewal pruning and formative pruning
Notes
Pruning sour cherries is generally less severe than for sweet cherries. Excessive pruning can lead to gummosis.
Pruning timing
Main pruning for shaping, thinning, and renewal. Promoting crown structure and fruiting wood. While the tree is dormant. Avoid frost periods.
Removal of water sprouts and diseased parts. Light corrections to improve ventilation. Only if necessary, to avoid weakening the plant.
Goal
Pruning is for shaping, maintaining vitality, promoting fruit yield, and disease prevention. Sour cherries are usually trained upright or as a bush/pyramid.

Tools and hygiene
Use sharp and disinfected tools (e.g., with alcohol) to prevent diseases.

The fruit (without pits) can be offered in very small quantities as an occasional treat. However, leaves, stems, bark, and pits contain cyanogenic glycosides, which are toxic if ingested and could be consumed by geese while foraging. Therefore, the plant as a whole is not suitable as feed.

The flesh of sour cherry is suitable for sheep in small amounts as an occasional treat, but pits, leaves, and twigs contain amygdalin, which can release cyanide when chewed or when wilted material is consumed. Sheep tend to browse and may ingest leaves and twigs, posing a poisoning risk. Only pit-free flesh should be offered occasionally. Seek veterinary help immediately if poisoning is suspected.

Pests
Aphids
Small, sucking insects that colonize young shoots and leaves, feeding on plant sap. They can cause deformities and honeydew.
Cherry fruit fly
A small fly whose larvae hollow out cherries from the inside, making them inedible.
Cherry aphid
A specialized aphid species that primarily infests young shoots and leaves of cherry trees.
Scale insects
Small, sessile insects living under a shield-like covering, sucking plant sap. They leave behind honeydew, which can lead to sooty mold.
Spider mites
Tiny arachnids that colonize the underside of leaves and suck plant sap, leading to fine speckling and later yellowish or bronze-colored leaves. Fine webbing visible with heavy infestation.
Diseases
Monilia blight (brown rot)
Fungal disease affecting blossoms, shoots, and fruits. Leads to wilting, shoot dieback, and fruit rot.
Bacterial canker
Bacterial disease affecting bark, leaves, and fruits. Causes bark necrosis, gummosis, and leaf fall.
Leaf spot diseases
Various fungi can cause leaf spots, leading to premature leaf fall and impairing photosynthesis.
Powdery mildew
Fungal disease appearing as a white coating on leaves, shoots, and fruits. Affects growth and fruit quality.
Verticillium wilt
Soil-borne fungal disease that affects the plant's vascular system, leading to wilting.
Deficiencies
Iron deficiency
Lack of iron leads to chlorosis, especially in young leaves.
Magnesium deficiency
Magnesium deficiency often appears as chlorosis on older leaves.
Potassium deficiency
Potassium deficiency affects water regulation and fruit development.

Diagnostic rules
Brown, mummified fruits remaining on the tree
Possible causes: Monilia blight
- Check for gray-brown fungal growth on the fruits.
Gummosis (oozing of sap) from bark cracks
Possible causes: Bacterial canker
- Look for dark, circular spots on the bark.
White, powdery coating on leaves and shoots
Possible causes: Powdery mildew
- Check whether the coating can be wiped off.
Yellowing of leaves between veins, veins remain green
Possible causes: Iron deficiency
- Mainly affects young leaves.
FAQ
When is the best time to plant a sour cherry tree?
The best planting times are spring (March-April) and autumn (October-November), allowing the tree to establish roots before bud break or winter, respectively.
How often do I need to water my sour cherry tree?
Sour cherries require regular watering, especially during dry spells and fruit development. Ensure you avoid waterlogging.
What diseases commonly affect sour cherries?
Common diseases include Monilia blight (brown rot), bacterial canker (gummosis), and various leaf spot diseases. Prevention through good care and resistant cultivars is important.
Can I grow sour cherries in containers?
Sour cherries are generally not suitable for container cultivation as they grow too large and develop deep root systems. Dwarf varieties on weak rootstocks might theoretically be possible but are not common.
