Establishment
1-2 yearsYoung tree focuses on root and branch development with minimal fruiting. Scaffolding branches begin to form.
Stake if needed. Remove competing leaders. Water consistently. Prune to establish open center or central leader form.
Juvenile Development
1-3 yearsTree grows vigorously, reaches productive size. First significant flowers may appear.
Continue formative pruning. Thin flower buds if excessive fruiting threatened. Maintain consistent water and fertility.
Flowering
2-3 weeksAbundant white blossoms appear in early spring before or as leaves emerge. Flowers are self-fertile but benefit from cross-pollination with compatible sweet or sour cherry varieties.
Protect from late frosts if possible. Ensure adequate pollinator activity. Thin flower clusters if overcrowded.
Fruit Development & Growth
4-6 weeksFruits develop from pollinated flowers, growing from green to red over 4-6 weeks. Medium-sized fruits (0.75-1 inch diameter) reach mature color by early-mid summer.
Thin fruits to 4-6 inches apart for larger specimens. Water regularly but not excessively. Monitor for pests and diseases.
Harvest & Dormancy
Harvest period 2-3 weeks; dormancy 4-5 monthsFully ripe fruits are dark red to nearly black, juicy, and ready for harvest. After harvest, tree enters dormancy in fall/winter.
Harvest when fully colored and slightly soft. Prune in late winter while dormant. Apply dormant oil if needed for pest prevention.
