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, and multi-season interest, suiting informal upright or semi-cascade styles — though it is a demanding subject: the 3–6 inch leaves reduce only modestly, wounds heal slowly, and branches die back readily under drought or root stress. 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.
- Type: Deciduous broadleaf; outdoor in Zone 7.
- Light: Partial shade (morning sun, afternoon shade) for best bracts.
- Watering: Every 2–3 days when topsoil dries; consistent moisture.
Skip to a season:
Spring (Mid-March – Mid-May)Summer (Mid-May – August)Fall (September – Mid-November)Winter (Mid-November – Early March)
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; do any structural pruning immediately after flowering, before next year's buds set.
- 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. Avoid early-spring cuts where possible — dogwood bleeds sap heavily then and wounds heal slowly.
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: Green fruit forms in summer and ripens red in fall.
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: Dead, diseased, or damaged wood only — next year's flower buds are already set, so structural cuts now remove next spring's bloom.
- 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: Dead or damaged wood only; no structural cuts (flower buds are already set).
- Wiring: Avoid.
- Repotting: Avoid.
- Pests/Diseases: None active; inspect for scale and overwintering eggs.
- 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.
