Dormant/Establishment
First winter, or several months for new plantingsLeafless period in winter; newly planted trees focus on root development
Plant in fall or early spring. Water well after planting. Apply 2-3 inches of mulch around base, keeping it 6 inches from trunk. Stake if necessary in windy areas.
Spring Growth & Flowering
4-6 weeksPink-tinged white flowers emerge in clusters; new foliage develops. This stage occurs in late April-May depending on zone.
Do not fertilize; allow tree to focus on blooming. Ensure adequate moisture. Monitor for early pests. Prune only dead/damaged wood.
Fruit Development
June-AugustSmall green fruit forms after flowers fade. Fruit gradually enlarges throughout summer. Foliage is full and deep green.
Thin fruit to 4-6 inches apart if overcrowded (optional, but improves size). Water during dry periods, especially important during this stage. Apply balanced fertilizer in early summer if needed.
Fruit Maturation & Ripening
Late August-SeptemberFruit turns from green to bright red. Tree prepares for dormancy as days shorten. Fall foliage color begins.
Reduce watering as fall approaches. Allow fruit to fully ripen on tree for best flavor. Monitor for late-season pests. Do not prune.
Harvest & Dormancy
September-DecemberFruit is ready for harvest; leaves drop in fall. Tree enters dormancy for winter rest.
Harvest fruit as it fully ripens. Clean up fallen fruit and leaves to reduce pest/disease carryover. Prune during dormancy (late winter) to shape tree and remove crossing branches.
