Intro
The Cotoneaster bonsai is a charming deciduous species known for its small, glossy leaves, delicate white or pink flowers, and clusters of bright red berries in autumn. With natural ramification and a calm, arching form, it’s a favorite for informal upright and cascading styles. Bonus? Pollinators love it too!
Care Instructions
Light
- Prefers full sun to partial shade.
- Full sun encourages tighter internodes, abundant flowering, and richer berry production.
Watering
- Keep soil consistently moist but not soggy.
- In warmer months, water daily or as needed, especially if potted shallowly.
- Let soil surface dry just slightly between waterings.
Temperature & Climate
- Hardy to USDA Zone 5–9.
- Cold-hardy, but young trees or small pots may need winter protection.
- Deciduous—drops leaves in autumn and rests during winter.
Pruning
- Structural pruning in late winter or early spring, before bud burst.
- Clip new shoots back to 2–3 leaves during growing season.
- Remove any suckers or overly vigorous upright shoots.
Repotting
- Repot every 2–3 years in early spring before budding.
- Cotoneasters tolerate root pruning well but don’t be too aggressive.
- Use a well-draining mix—bonsai soil with some organic matter works well.
Seasonal Tips
- Spring: Prune and repot. Feed lightly once leaves emerge.
- Summer: Clip new shoots; watch for aphids and scale insects.
- Autumn: Enjoy the berry display! Prepare for leaf drop.
- Winter: Protect roots from deep freeze. Minimal watering needed.
Companion Moss & Plants
- Creeping thyme, low sedum, or Irish moss pair beautifully.
- Moss helps retain soil moisture but ensure airflow remains around the roots.
Display Suggestions
- Gorgeous in oval or rounded pots that emphasize flow.
- Style in semi-cascade or informal upright to showcase arching growth and berries.
- Accent the red berries with muted pot colors (gray, slate, or pale blue).
- Pairs well with a seasonal display stone or small bird figurine to echo its garden-like vibe.
