- Maintenance Pruning: Pinch back new shoots during summer for refined growth.
- Flower Bud Management: Since flowers form on older wood, avoid pruning heavily after summer.
- Wiring: Use aluminum or copper wire carefully during the dormant season to shape branches, but remove it within 6 months to avoid scarring.

Repot a dogwood bonsai tree every 2–3 years in early spring before new growth starts. Use well-draining bonsai soil and trim about one-third of the root system.
Steps:
- Gently remove the tree from the pot.

- Refresh with nutrient-rich bonsai soil.
- Water thoroughly after repotting.
- Place in semi-shade for 2–3 weeks to reduce transplant stress.
Dogwood Bonsai Winter Care
Dogwood bonsai winter care is crucial for survival in colder climates.
- Cold Hardiness: Most dogwood bonsai trees tolerate cold but require protection from freezing winds.
- Storage Options: Cold frames, unheated sheds, or burying pots in mulch.
- Avoid Indoor Overwintering: Unless temperatures are extreme, avoid keeping indoors for the entire winter—it may interrupt dormancy.
