Establishment
1-2 yearsYoung tree is developing root system and branch structure. Growth is upright and relatively slow.
Water regularly during first 2-3 years. Stake for support if needed. Prune only to remove dead or crossing branches. Mulch base to retain moisture.
Budding
6-8 weeksFlower buds form in late summer/early autumn on the previous season's growth. Buds remain dormant through winter.
Ensure adequate chilling hours (400-600 hours below 45°F). Avoid late nitrogen fertilization which delays dormancy. Monitor for frost damage to buds.
Flowering
2-4 weeksDouble flowers appear in early spring (January-March depending on region), with pink to deep rose petals. Highly fragrant and ornamental.
Protect young blossoms from late frosts. Provide pollinators access. Thin excessive flower clusters if desired. Deadhead spent flowers to redirect energy.
Fruiting
8-12 weeksSmall, round fruits (1-1.5 inches) develop from pollinated flowers. Green fruits mature to yellow or yellow-green by early summer.
Thin fruits when marble-sized to improve size and quality. Water consistently during fruit development. Provide light fertilizer if needed.
Harvest & Dormancy
4-6 weeks harvest window, then 5-6 months dormancyFruits ripen mid-spring to early summer. Tree prepares for dormancy in late autumn with leaf color change.
Harvest fruits when fragrant and yielding slightly to pressure. Allow tree to enter dormancy naturally. Prune in late winter after frost danger passes.
