- Cone: Small oval brown cones, 0.5–1 cm long, maturing in one growing season.
- Stem/Bark: Reddish-brown, fibrous, peeling in thin strips as the tree ages.
Care Guide
Watering
Water regularly during prolonged dry spells to maintain consistent soil moisture
Fertilization
Apply a balanced slow-release fertilizer once to support new growth. Use a low-nitrogen fertilizer to promote dense foliage without excessive leggy growth.
Eggshell powder topdress：Crush clean, dried eggshells into fine powder, sprinkle 1–2 tbsp around the tree base, and water in to release calcium slowly.Pruning
- Prune in late winter to early spring to shape hedges or remove dead, damaged branches.
- Thin dense foliage to improve airflow and reduce risk of fungal diseases.
- Avoid heavy pruning of mature trees; focus on removing crossing or overcrowded branches to maintain form.
