How to Grow Japanese Dogwood
Japanese Dogwood
Cornus kousa
treeJapanese Dogwood is a deciduous ornamental tree native to East Asia, prized for its four-petaled white or pink flower bracts that appear in early summer, followed by strawberry-like red fruits and attractive exfoliating bark. It grows 15-30 feet tall with a spreading, layered canopy and provides stunning multi-season interest including brilliant red to purple fall foliage. Unlike flowering dogwoods, this species is more disease-resistant and heat-tolerant, making it an excellent landscape choice.

Establishment
First 12 monthsNewly planted young tree with developing root system and initial branching framework
Water consistently 2-3 times weekly during first year. Mulch around base with 2-3 inches of organic material. Avoid fertilizer first year. Plant in spring or fall.
Young Growth
Year 2-3Tree establishes characteristic tiered branching habit, grows 1-2 feet per year, begins developing thicker stems
Continue regular watering during dry periods. Prune only to remove crossing or damaged branches. Minimal fertilization needed in average soil.
Maturation
Year 4-10Tree reaches mature size and form, develops dense canopy with distinctive layered appearance
Transition to occasional deep watering during extended drought. Pruning to maintain shape can be done in late winter; avoid heavy pruning as this species has naturally excellent form.
Flowering
4-6 weeks in early summerCreamy-white (sometimes pink-tinged) flower bracts appear in early summer (June-July), creating showy display above foliage
Ensure adequate sun exposure for best flower production. Do not prune during flowering season. Mature trees at peak flowering require minimal intervention.
Fruiting & Fall Interest
August through first frostRed, strawberry-like aggregate fruits develop by late summer and persist into fall; foliage turns deep red to purple, exfoliating bark becomes more visible
Leave fruits on tree for ornamental value and wildlife food. Rake fallen leaves if desired for lawn appearance. Do not prune; enjoy the natural structure.

Fun Facts
- 🌱 Japanese Dogwood's distinctive four-petaled 'flowers' are not true petals but modified leaflike bracts surrounding inconspicuous true flowers; the showy display is actually an elegant botanical disguise.
- 🌱 The exfoliating bark becomes increasingly attractive with age, creating a mottled pattern of tan, gray, and brown that provides winter interest even after all leaves have fallen.
- 🌱 Japanese Dogwood is significantly more resistant to dogwood anthracnose disease than American flowering dogwood (Cornus florida), prompting many horticulturists to recommend it as a superior landscape replacement.
