Flowering Dogwood (Cornus florida) Bonsai Care Timeline

Flowering Dogwood (Cornus florida) is a small deciduous tree native to eastern North America, from southern Maine to northern Florida and west to eastern Texas. It grows as an understory species in moist, acidic, well-drained woodlands and forest edges, reaching 15–30 feet tall with a horizontal, layered branching habit, bright green leaves, and showy white or pink bracts (modified leaves) surrounding small flowers in spring.

The bracts create a spectacular spring display, followed by red berries in fall that attract birds, and leaves turning deep red-purple in autumn. The bark develops blocky, alligator-like patterns with age. In bonsai, Flowering Dogwood is prized for its elegant branching, reliable bloom on short spurs, good leaf reduction, and multi-season interest, suiting informal upright or semi-cascade styles. It is popular in the USA for native yamadori and flowering bonsai. In USDA Zone 7 it is hardy outdoors and blooms profusely with partial shade and acidic soil.

Deciduous broadleaf; outdoor in Zone 7.

Spring (Mid-March – Mid-May)

Goal: Maximize bract display and new growth.

  • Light: Partial shade (morning sun, afternoon shade) for best bracts.
  • Watering: Every 2–3 days when topsoil dries; consistent moisture.
  • Fertilizing: Acidic or balanced bloom-booster as buds swell.
  • Pruning: Remove spent bracts and pinch new shoots after bloom.
  • Wiring: Late spring on new growth.
  • Repotting: Every 2–3 years early spring; acidic, well-draining mix. Trim roots lightly.
  • Pests/Diseases: Dogwood anthracnose, powdery mildew; copper fungicide preventive.
  • Notes: Prune after bloom to preserve next year's buds.

Summer (Mid-May – August)

Goal: Develop ramification and fruit set.

  • Light: Partial shade during heat.
  • Watering: Daily; high humidity preference.
  • Fertilizing: Acidic every 3–4 weeks; low-nitrogen after mid-summer.
  • Pruning: Pinch shoots to 2–3 leaves.
  • Wiring: Monthly checks.
  • Repotting: Avoid.
  • Pests/Diseases: Anthracnose, borers; improve airflow and treat early.
  • Notes: Red berries form late summer.

Fall (September – Mid-November)

Goal: Enjoy berries and fall color; structural work.

  • Light: Partial to full sun.
  • Watering: Reduce to every 3–5 days.
  • Fertilizing: Low-nitrogen early fall.
  • Pruning: Major structural after leaf drop.
  • Wiring: Good time for shaping.
  • Repotting: Avoid.
  • Pests/Diseases: Low.
  • Notes: Brilliant red-purple fall leaves and red berries.

Winter (Mid-November – Early March)

Goal: Dormancy protection.

  • Light: Bright shelter.
  • Watering: Sparingly.
  • Fertilizing: None.
  • Pruning: Dormant structural cuts.
  • Wiring: Avoid.
  • Protection: Mulch pot; cold frame below 10°F.
  • Notes: Hardy; layered branching shines in winter.

Zone 7 Tips: Acidic soil and partial shade key; outstanding for spring bract display and native elegance.
