Establishment
1-2 yearsYoung tree focuses on root development and branch formation with minimal fruiting
Water regularly during first year. Support with stake if needed. Prune to establish strong central leader and scaffold branches.
Vegetative Growth
2-3 yearsTree develops full canopy structure and reaches mature size (20-25 feet tall and wide)
Prune annually in late winter to remove crossing branches and maintain form. Thin branches for air circulation. Begin light fruit thinning if desired.
Flowering
2-3 weeksSpring brings abundant clusters of white to pale pink blossoms covering the entire canopy
Flowers appear in April-May depending on zone. No special care needed; ensure pollinator access. Blossoms are self-fertile but cross-pollination improves fruit set.
Fruiting
3-4 months (June-September)Small red apples (0.75-1 inch diameter) develop from June through August, maturing to bright red
Fruit thinning to 4-6 inches apart improves size. Monitor for pests and diseases. Begin harvesting when fruit reaches full color and slight give when squeezed.
Dormancy
4-5 monthsTree loses leaves in fall after brief yellow foliage display; red fruit may persist into winter
Late winter is ideal pruning time before growth resumes. Remove diseased or dead wood. Fruits left on tree provide winter wildlife food.
