Sour Cherry
Prunus cerasus
treeSour cherry trees are small to medium-sized deciduous fruit trees that produce tart, bright red cherries ideal for cooking, baking, and preserves. Unlike sweet cherries, sour cherries are largely self-fertile and more cold-hardy, making them suitable for home gardens in cooler climates. They typically grow 15-25 feet tall and live 20-30 years with proper care.

Establishment
1-2 yearsYoung tree focuses on root and branch development with limited flowering the first 1-2 years
Remove early flower buds to encourage root establishment. Water deeply 1-2 times weekly. Stake for wind protection. Apply 2-3 inches of mulch around base.
Vegetative Growth
2-4 yearsTree develops strong scaffold branches and expands canopy; foliage is vibrant green
Prune to open center form in late winter. Remove crossing/diseased branches. Maintain regular watering schedule. Apply balanced fertilizer in early spring.
Flowering
2-3 weeks in springTrees produce abundant white to pale pink blossoms in early spring before leaves emerge
Blooms appear on year-old wood. Protect flowers from late frost with frost cloth if needed. Do not heavily prune during flowering. Ensure adequate pollinator access.
Fruit Development
6-8 weeks post-floweringSmall green cherries form and gradually enlarge, turning from green to red over 6-8 weeks
Thin fruit to 1 cherry every 2-3 inches for larger fruit and easier harvest. Water consistently during this stage. Monitor for pest damage and diseases. Avoid high-nitrogen fertilizer.
Harvest
2-4 weeks depending on variety and weatherCherries reach full red color and develop peak acidity and flavor; ready for picking
Harvest when fully red and slightly soft to touch. Pick with stems intact to reduce damage. Harvest in morning after dew dries. Cherries continue ripening on tree; pick at full color for best flavor.

Harvest Tips
Sour cherries ripen in mid to late summer (June-August depending on zone). Harvest when fully red and firm; pick in the morning for best flavor. Use pruning shears or gently twist and pull with stem attached to prevent branch damage. Cherries do not continue to ripen after picking, so ensure full color development on tree. A mature tree yields 30-50 pounds of cherries per season.
