First 1-2 yearsYoung transplant with developing root system; minimal branching
Water regularly to establish roots. Avoid deep cultivation around base. Apply 2-3 inches of mulch. Stake if tall to prevent wind damage.
Vegetative Growth
Years 2-4Plant develops branching structure and foliage; multiple stems emerging
Prune only to remove dead/crossing branches. Maintain consistent moisture. Fertilize lightly in early spring if growth is slow.
Flowering
3-4 weeks in spring (April-May, depending on zone)White, pink, or red four-petaled flowers emerge on branch tips before leaves, creating showy spring display
Do not prune during flowering. Maintain adequate moisture. No special fertilization needed for flowering.
Fruiting & Foliage
June-SeptemberSmall red drupes (berries) develop after flowers fade; dark green glossy foliage present through summer
