🌿 Carmona (Ehretia) microphylla Bonsai Care
☀️ Light
Bright, indirect sunlight is ideal.

Can tolerate some direct morning sun, but avoid strong midday sunlight to prevent leaf scorch.

Needs 12–16 hours of light daily for optimal growth—consider a grow light in darker climates.

💧 Watering
Keep the soil consistently moist, not soggy.

Water when the topsoil feels slightly dry.

Reduce watering in winter, but do not let it dry out completely.

Avoid cold or hard water—use room-temperature rainwater or filtered water if possible.

💨 Humidity
Prefers high humidity—at least 50–60%.

Use a humidity tray, or mist the leaves daily, especially in heated indoor environments.

🌡️ Temperature
Thrives in 15–25°C (59–77°F).

Protect from cold drafts and sudden temperature changes.

Minimum temperature: 10°C (50°F).

🌱 Soil
Use well-draining bonsai soil mix (e.g., akadama, pumice, and lava rock).

Avoid soils that retain too much moisture.

🌼 Fertilizing
Feed every 2–3 weeks during spring and summer with a balanced liquid fertilizer (e.g., 10-10-10).

Reduce feeding to once a month in autumn and winter.

Avoid fertilizing a stressed or recently repotted tree.

✂️ Pruning & Shaping
Prune regularly to maintain shape—trim new shoots after 6–8 leaves.

Wiring is possible, but branches are brittle, so be gentle.

Remove dead or weak branches.

🪴 Repotting
Repot every 2–3 years in early spring before new growth starts.

Trim roots moderately and replace old soil to prevent compaction.

🐛 Pests & Problems
Watch for aphids, spider mites, and scale insects.

Treat with neem oil or insecticidal soap.

Leaf drop can result from poor lighting, over/under-watering, or sudden environmental changes.
